The Importance of Homocysteine

Homocysteine is an amino acid that is produced in the body. Although this can be a vital substance in the body, increased homocysteine levels is associated with high cholesterol and build up of materials such as white blood cells, calcium and plaque in blood vessels. The increased materials in blood vessels increase the risk of heart attack, stroke, and pulmonary embolism. Therefore, a high homocysteine level is a usual indicator of an increased risk factor of heart complications. High homocysteine can be corrected by applying proper diet and routine homocysteine testing.

Homocysteine is a marker of bad health which makes it critical for an individual to monitor their homocysteine levels. Consistent homocysteine testing is essential to people with a family history of heart diseases. Homocysteine testing is also important for people who have a history of heart diseases without a described cause. With the complication of heart diseases, homocysteine testing is an information gateway reflecting the heart conditions of a patient.

Homocysteine Blood Tests

Keeping a low homocysteine level is done through homocysteine blood tests. The application of homocysteine blood tests does not only indicate the outlook of one’s health and wellness. In addition, a homocysteine blood test is done to help determine the risk of heart disease, stroke and condition of the blood vessels.

Homocysteine levels are also an indication of vitamin B12 deficiency or folic acid deficiency. A high level of homocysteine blood test results usually indicates nutritional deficiency. However, there is also wellness panel test to measure different kinds of nutrition deficiencies.

Homocysteine testing helps identify the occurrence of homocystinuria. This rare disease causes heart complications and delayed growth in babies. A high homocysteine level is a result of enzyme deficiency caused by homocystinuria. It is evident that homocysteine testing has numerous applications aside from measuring the general health and wellness of a person.

Homocysteine Test Information

Preparing for a homocysteine blood test involves a set of guidelines to produce accurate results. For starters, one should not eat or drink anything except water for ten to twelve hours. In addition, there are different drug interactions that can modify the homocysteine test results. Your doctor should know any prescription drugs that you take before taking homocysteine tests. Finally, allow the doctor
to interpret the homocysteine test results for you, so that you are left completely satisfied with the meaning of your homocysteine levels.

If you think you are pregnant
, you may want to test yourself at home with a home pregnancy test. You can buy test kits at a drug store without a prescription
. Home use kits measure a hormone called human chorionic gonadotropin (hCG) in your urine. However, these tests are qualitative, the results are either positive or negative for pregnancy. Many home pregnancy tests claim to be 99 percent accurate on the day you miss your period. It most home pregnancy tests don’t consistently spot pregnancy this early, the tests are considered reliable when used according to package instructions one week after a missed period. The hormone is released in a pregnant woman’s urine.

Home pregnancy tests and how they work

Home pregnancy tests measure the presence of a telltale hormone in your urine called human chorionic gonadotropin (hCG). This hormone, produced by cells from the placenta, first gets into your bloodstream when the fertilized egg implants in your uterus (on average 8 to 10 days after fertilization). The amount of human chorionic gonadotropin (hCG) in your body then increases rapidly over the next few weeks, doubling in amount about every two days.

There are two main types of pregnancy tests. Both are commonly used to detect pregnancy.

Home pregnancy tests are available at your local drugstore or pharmacy and at some large department stores. Blood pregnancy tests are performed by health care professionals in an office or a clinic. Home pregnancy tests are usually about 97% accurate, but this varies from brand to brand. The amount of human chorionic gonadotropin (hCG) in your body then increases rapidly over the next few weeks, doubling in amount about every two days. HCG can also be detected in your blood, around 10 days after you conceive, and your GP may advise you to have a blood test.Pregnancy blood tests are performed health clinic. They detect pregnancy by measuring hCG levels in your blood. The most sensitive test of pregnancy is best performed by a laboratory using a sample of your blood.

Blood tests performed at your clinic have a 99% accuracy rate and can detect pregnancy earlier than most urine tests. Blood tests can be performed 7 days after you ovulate and still provide accurate results. Some urine tests can be used on the first day that your period is due, however, it is unlikely that you will achieve that 97% accuracy rate if you test so early. The quantitative blood test detects pregnancy by measuring the exact amount of hCG in your bloodstream. It can also be used to detect how far along you are in your pregnancy. It does not measure your hCG levels, and only provides a yes or no answer as to whether or not you are pregnant. Home pregnancy tests only check hCG levels, not progesterone. They are completely different hormones.

So how can all these tests claim to be accurate so early in pregnancy?

They don’t. They only claim to be “greater than 99 percent accurate” in general, and then separately, they suggest that you can use them as early as the day you miss your period. If you think you are pregnant

Hypoglycemia
happens if your blood glucose drops too low. It can come on fast. Hypoglycemia is not a disease.

Symptoms of low blood glucose include weakness, hunger, sweating, and feeling nervous or restless. If you develop these symptoms during the test, you may have your sugar level checked quickly with a glucose meter
. Symptoms of hypoglycemia may not be obvious in newborn babies. The following are the most common symptoms of hypoglycemia.

Blood glucose may be measured on a fasting basis (collected after an 8 to 10 hour fast), randomly (anytime), post prandial (after a meal), and/or as part of an oral glucose tolerance test (OGTT / GTT). An OGTT is a series of blood glucose tests.

Blood glucose monitors have been found to be accurate and reliable if correctly used, and most monitors provide results within two minutes. Some glucose monitors can also give verbal testing instructions and verbal test results for people who are visually or physically impaired. Blood insulin levels are measured before the injection, and again at 1 and 3 minutes after the injection. This test may predict the development of type 1 diabetes in some patients.

Blood insulin levels are measured before the injection, and again at 1 and 3 minutes after the injection. This test may predict the development of type 1 diabetes in some patients. Blood glucose levels that vary widely may indicate a problem. This test is also called a casual blood glucose test. Blood glucose is the body’s major fuel for the energy it needs. When insulin is absent or ineffective, the blood glucose level increases.

Diabetes and its complications are major causes of morbidity and mortality in the United States and contribute substantially to health-care costs. However, these surveys rely only on self-reports of previously diagnosed diabetes and cannot measure the prevalence of undiagnosed diabetes. Diabetes must be confirmed with a blood test. In one test, glucose is given to the patient in a beverage, after which blood samples are drawn and tested at intervals.

Glucose concentrations in sodium fluoride samples are consequently lower than in promptly separated serum samples (by approximately 7-12%). Glucose-galactose malabsorption generally becomes apparent in the first few weeks of a baby’s life. Affected infants experience severe diarrhea resulting in life-threatening dehydration, increased acidity of the blood and tissues (acidosis), and weight loss when fed breast milk or regular infant formulas.

Glucose is critical in the production of proteins and in lipid metabolism. Also, in plants and most animals, it is a precursor for vitamin C (ascorbic acid) production.

Glucose is carried to each cell through the bloodstream. Cells, however, cannot use glucose without the help of insulin . Glucose is a normal constituent of the blood of animals ( see Sugar Metabolism ).

Glucose is absorbed from the gastrointestinal tract directly and is also derived from digestion of other dietary carbohydrates. It is also produced inside cells by the processes of glycogen breakdown (glycogenolysis) and reverse glycolysis (gluconeogenesis).

Alcohol tests are conducted to know whether the person has consumed alcohol or not. Alcohol testing is conducted in different ways using urine, blood, saliva and breathe specimens. Every test has its own importance and advantages of using it. Results of some alcohol testing can be used as evidence for legal considerations.

Types of alcohol testing
Basically there are four types of alcohol tests. They are Urine alcohol test, Blood alcohol test, Alcohol breathalyzer test and Saliva alcohol test. The following are the different types of alcohol testing.

• Urine Alcohol Test:
As the name goes urine alcohol test is conducted on urine specimen of the person for whom the test is conducted. This test indicates the presence of alcohol in a person’s body, but it takes up to 2 hours for alcohol to show up in person’s urine. Urine alcohol test is less expensive when compared to other alcohol tests. This test can also be conducted at home but for accurate results lab verification is required.

• Blood Alcohol Test:
Blood alcohol test is accurate and expensive when compared to other alcohol tests. Blood alcohol test is conducted on blood specimen and helps in identifying the actual content of alcohol present in blood. Blood tests are least used method in testing for alcohol because of their high cost.

• Alcohol Breathalyzer Test:
The common form of breath alcohol testing is breathalyzer test. Blood Alcohol Content (BAC) is indirectly estimated by measuring the amount of alcohol in one’s breath. There may be inaccurate results due person’s breathing rate may change by vigorous exercise. If law enforcement personnel fail to use the breathalyzers properly or fail to maintain the device properly, then the results may not be accurate.

• Saliva Alcohol Test:
Presence of alcohol is tested through saliva specimen of the person for whom the test is conducted. This test is expensive than urine test and most commonly used test when compared to other tests. Samples are collected at the time of test and chance of tampering the sample is less. There are no nationally accepted cutoff levels for this test. Therefore, the results of saliva alcohol test are not accepted as evidence for any legal consideration.

To prevent road accidents, legislators are using these tests and making high efforts in controlling the accidents which are caused due to driving under the influence of alcohol. Testing for alcohol has become common for evaluation of employee. For avoiding accidents and evaluating employees, alcohol testing has become more important and is implemented more commonly than earlier.

Do you know if you have diabetes or not? Do you know what blood sugar normal levels are? Do you know what your numbers are? If not, take the time to have it done. Here is why this is so important.

Blood Sugar Normal Level Test

A blood sugar normal level or blood glucose level measures how well a person’s body is processing the sugar that is taken in through the diet. Test results can be obtained by a simple finger stick with a glucometer or with a traditional laboratory blood test. There are different tests that can determine blood sugar levels at various stages, such as a fasting, random, 2-hour glucose tolerance test, and glycated hemoglobin test. All of these tests measure blood sugar normal levels with a simple procedure, but the results can differentiate between normal, pre-diabetes, and type 1 or type 2 diabetes. There may also be other signs and symptoms present that are indicative of a blood sugar level being too low or too high.

Most of the time a blood sugar level is drawn randomly, unless the primary doctor has specifically requested a patient to fast before having the test done. A random test does not take into consideration the last time a person ate a meal or a snack. According to doctors, blood sugar normal levels reading should be less than 100 mg/dL; pre-diabetes is suggested if the level is greater than 100 mg/dL but less than 199 mg/dL. A level above 200 mg/dL or higher is indicative of either type 1 or type 2 diabetes. A fasting blood sugar level is drawn after an eight hour period with no food or beverages with sugar or calories.

This test is usually drawn first thing in the morning, and a blood sugar normal level is considered to be below 70 mg/dL. If diabetes is suspected after preliminary tests, then a 2-hour glucose tolerance test is ordered. Fasting is also required for this test to get accurate results. Patients first drink a sugary liquid and then have their blood drawn two hours later. A normal reading is less than 140 mg/dL, pre-diabetes is suggested if level is between 140-199 mg/dL, and type 1 or type 2 if level is 200 mg/dL or higher. The glycated hemoglobin or hemoglobin A1C test is used not to diagnose diabetes, but to manage ongoing treatment. It measures the average blood sugar level for the previous three month period, and indicates how well diabetes has been managed during that time.

It is recommended that everyone have their blood sugar level checked from time to time to make sure that glucose is within the normal range. Low and high blood sugar levels are usually accompanied by symptoms that are related to how low or high glucose is in the bloodstream. Once diabetes is diagnosed, patients are instructed on how to control the disease, cut out refined sugar from the diet, get adequate exercise on a regular basis, and follow their prescribed plan of care. If you will continue to test your blood sugar normal level, you’re more likely to live a happy and healthy life for many years to come.

An early pregnancy test can be conducted in two ways: at home through a home testing kit or at the doctor’s. When you go to the doctor, you may request for a blood or urine test. Both these tests are identical in that they look for traces of the pregnancy hormone. This hormone is unique because it is produced in the body only when the woman becomes pregnant.

Blood tests performed at the healthcare center are of two types. The qualitative hCG test is very much like a urine test, and it can simply give you a confirmation of pregnancy. For greater accuracy, it is important to go for a quantitative blood test which measures the exact amount of hormone in the blood. This test, due to its very nature, can pick up even very small traces of the hormone and is therefore very accurate. Blood tests are performed by taking a tube of blood from the vein, which is sent to the laboratory for examination. The analysis may take anywhere from a few hours to a day max.

Blood tests are generally more accurate than urine tests, and they are also quicker in offering you confirmation of pregnancy because traces of hCG appear about a week earlier in the blood than in the urine. While blood tests can determine pregnancy about a week after ovulation, urine tests take 14-16 days to come out with an accurate result. However, these days there are more sensitive urine tests that can give you a confirmation as early as a week after ovulation.

Now-a-days, many women opt for home pregnancy tests, which also test for the presence of this hormone. In this case, a strip is held to a stream of urine for a prescribed amount of time, after which the strip may develop certain color differences or markings in case the test is positive. It is generally recommended that the first urine of the day be used for the test because this is more concentrated.

Home pregnancy test kits are available in pharmacies and you do not require a doctor’s prescription to buy one. On the positive side, these tests are convenient and they ensure that your privacy is protected. On the negative side, early results may be misleading and you need to wait longer or go for an alternative blood test to be completely sure of the results. Sometimes a false negative test may say that you are not pregnant even though you have conceived. Wrong test results from home pregnancy test kits may have various reasons, including human error. In fact, they leave large room for errors caused by human carelessness. If the strip is not dipped properly or if you have not followed instructions properly, you run the risk of getting a false test result.

So it is advisable to take any negative results from a home pregnancy test with a pinch of salt. To be doubly sure, take the test again after a few days when the amount of hormone in your blood has increased, or better still, opt for a blood test.

In this day and age, we’ve all been told that STD testing is important for those who are sexually active, but there is a lot more to know about STD testing than “just do it.” Who is a candidate for STD testing? What’s involved in the process? When should you be tested for STDs? Why is it so important? Learn what everybody ought to know about STD testing and how getting tested for STDs has never been easier and more convenient.

STD Testing – The Basics

Everyone, sexually active or not, needs to have basic knowledge of STDs and STD testing.

Anyone who is sexually active should receive routine STD testing. This means anyone who participates in sexual activity of any kind, not just vaginal intercourse, is at risk. The risk of contracting a sexually transmitted disease
is increased for those who have more than one sexual partner.

STD testing can be performed at your doctor’s office or local lab. There are various types of STD tests, and not all doctors test for the same diseases. Some STDs may be tested for using blood tests, urine, or cell samples. You may need to have multiple tests depending on your sexual history and possible symptoms.

When it comes to STD testing, the sooner you have it done, the better. Like most diseases, the earlier it is caught, the easier it will be to treat. If you have symptoms of a sexually transmitted disease, the best thing to do is to have yourself and your partner tested. If you’re thinking of becoming sexually involved with a new partner, both you and your partner should be tested first. If you have more than one sexual partner, STD testing is recommended yearly.

The Importance of STD Testing

STD testing is important to protect your health and the health of your partner and future partners. The truth is that most people who transmit STDs don’t even know they have one. That knowledge can be obtained in a simple test and can help protect both you and your partner.

The spreading of STDs is preventable. Diseases such as Chlamydia, gonorrhea, and syphilis are easily curable with simple antibiotics. But in order to treat these STDs, you must be aware of them. STD testing is the first step.

You have a responsibility to receive STD testing, not only to protect your partner and to prevent the spreading of STDs, but also to yourself, your body, and your health.

A breakthrough in Celiac testing has become available to Canadians suffering from gluten intolerance symptoms.

2G Pharma Inc. is now offering the at-home test for IgA tissue transglutaminase antibodies (tTG) called the Biocard™ Celiac Test. The test is the first home Celiac test approved by Health Canada for the diagnosis of Celiac disease.

Celiac disease is a serious, lifelong, gastrointestinal disorder that can cause a wide spectrum of clinical symptoms such as diarrhea, abdominal distension, weight loss, malnutrition and skin disorders due to permanent intolerance to gluten, a complex mixture of proteins found in wheat, barley and rye.

Celiac symptoms
are numerous and varied making it difficult to diagnose. Patients often feel “lousy” for as long as 10 years while continuing to eat gluten, since they don’t know what is wrong.

Until now, Celiac testing in Canada required a physician to first consider Celiac disease as a potential cause of the symptoms, and then order Celiac blood tests which can take up to 3 weeks for results. Depending on the province and the patients’ medical plan, a fee may be required for these tests.

This simple home blood test is good news to the 1 out of 100 people who suffer from Celiac symptoms. Women are twice as likely to have Celiac disease. People most at additional risk of developing the disease are individuals with Type I diabetes or those who are relatives of Celiac patients.

If Celiac disease is left undiagnosed and untreated there is an increased risk of infertility, osteoporosis and intestinal cancer. If you are diagnosed with Celiac, early screening of your children, siblings, and parents is important, as their risk factor for the disease is 1 in 10! Celiac disease can strike at any age and approximately 97% of those affected are still undiagnosed.

The new Biocard Celiac Test can now be purchased online at www.celiachometest.com or at selected stores, for only $50. and in less than 10 minutes you can perform the test and get immediate test results!

In recent years in order to help the millions of people who suffer from mental illnesses, a variety of prescription drugs have been developed and put on the market. Seroquel (generic name quetiapine) is an antipsychotic medication manufactured by Astra Zeneca. Seroquel is prescribed for the management of symptoms of schizophrenia and manic episodes associated with bipolar disorder such as hallucinations, delusions or mental preoccupations beyond the control of a patient. Bipolar disorder is a serious mental illness that affects approximately three to four percent of the adult population and it is the sixth leading cause of disability in the world.

Like many of the “super drugs” manufactured and marketed by pharmaceutical companies, the exact mechanism that enables Seroquel to work for schizophrenic patients is not known. Seroquel targets the specific areas of the brain that secrete the neurotransmitters dopamine and serotonin. These are both chemicals that regulate the nervous system’s response to environmental stimuli. Certain mental disorders may be caused by excessive levels of these neurotransmitters. Seroquel is said to have an “antagonistic” effect on certain dopamine and serotonin receptors in the brain, allowing the chemicals to flow and function normally in the body.

The U.S. Food and Drug Administration (FDA) initially approved Seroquel in early 2004. When a drug, such as Seroquel, is prescribed as off-label, it means that the medication is prescribed beyond originally FDA approved disorders. Some of the other conditions that Seroquel is prescribed to treat include post-traumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), general anxiety disorders, sleep disorders and depressive episodes associated with bipolar disorder. Within the brain, the histamine receptor, which is the part that produces a sedative effect, is antagonisitically effected with Seroquel. For this reason Seroquel is often prescribed for insomnia and other sleep disorders, especially those associated with depression and other mental illnesses.

Psychotropics is a category of medications, under which Seroquel is categorized. While Seroquel is found to have effectively treated many patients, the negative side effects seriously outweigh the positive treatments of the drug. However, Seroquel has been known to reduce psychotic tendencies in patients as well as result in a clinical remission for a length of time, according to pre-market clinical trials for the drug.

However, there have been reports of elevated blood sugar and diabetes associated with the use of Seroquel and other drugs in its class. Individuals who have diabetes or possible risk factors such as obesity, or whose family has a history of diabetes, should speak with their doctor before taking Seroquel. Continual regulation and testing of Seroquel patients’ blood levels is important. Symptoms of elevated blood sugar or diabetes, including excessive thirst, increased urination, overeating, or weakness, are indications of serious side effects. Complications from elevated blood sugar or diabetes can be life-threatening.

Alternative treatments for Seroquel are highly advisable for patients currently taking the drug. Any individual who believes they may have been harmed or suffered adverse heath effects from the usage of Seroquel should seek the advice of an attorney who specializes in pharmaceutical litigation.
