Glucose Tolerance Test

A glucose tolerance test can show when the body can't manage blood sugar (glucose) levels well but not yet to the stage of diabetes. What is a glucose tolerance test? A glucose tolerance test checks how well the body processes blood sugar (glucose). It involves comparing the levels of glucose in the blood before and after drinking a sugary drink. The results of this test can help doctors to detect type 2 diabetes or pre-diabetes (impaired glucose tolerance). It is also used to help diagnose diabetes in pregnancy. How does a glucose tolerance test work? In most people a simple blood test is enough to detect diabetes. However, some people have 'borderline' results on routine blood tests and then a glucose tolerance test may help. Also, a glucose tolerance test can show when the body can't manage blood sugar (glucose) levels well but not yet to the stage of diabetes. This is known as pre-diabetes (impaired glucose tolerance) and is a condition that can lead to diabetes. In healthy people, glucose levels in the blood always rise after a meal but they soon return to normal as the glucose is used up or stored. A glucose tolerance test helps to distinguish between this normal pattern and Continue reading >>

What is POINT-OF-CARE TESTING? What does POINT-OF-CARE TESTING mean? POINT-OF-CARE TESTING meaning - POINT-OF-CARE TESTING definition - POINT-OF-CARE TESTING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6Uu... Point-of-care testing (POCT), or bedside testing is defined as medical diagnostic testing at or near the point of care—that is, at the time and place of patient care. This contrasts with the historical pattern in which testing was wholly or mostly confined to the medical laboratory, which entailed sending off specimens away from the point of care and then waiting hours or days to learn the results, during which time care must continue without the desired information. Point-of-care tests are simple medical tests that can be performed at the bedside. In many cases the simplicity was not achievable until technology developed not only to make a test possible at all but then also to mask its complexity. For example, various kinds of urine test strips have been available for decades, but portable ultrasonography did not reach the stage of being advanced, affordable, and widespread until the 2000s and 2010s. Today portable US is often viewed as a "simple" test, but there was nothing simple about it until the more complex technology was available. Similarly, pulse oximetry can test arterial oxygen saturation in a quick, simple, noninvasive, affordable way today, but in earlier eras this required an intraarterial needle puncture and a laboratory test; and rapid diagnostic tests such as malaria antigen detection tests rely on a state of the art in immunology that did not exist until recent decades. Thus, over decades, testing continues to move toward the point of care more than it formerly had been. A recent survey in five countries (Australia, Belgium, the Netherlands, the UK and the US) indicates that general practitioners / family doctors would like to use more POCTs. The driving notion behind POCT is to bring the test conveniently and immediately to the patient. This increases the likelihood that the patient, physician, and care team will receive the results quicker, which allows for better immediate clinical management decisions to be made. POCT includes: blood glucose testing, blood gas and electrolytes analysis, rapid coagulation testing (PT/INR, Alere, Microvisk Ltd), rapid cardiac markers diagnostics (TRIAGE, Alere), drugs of abuse screening, urine strips testing, pregnancy testing, fecal occult blood analysis, food pathogens screening, hemoglobin diagnostics (HemoCue), infectious disease testing and cholesterol screening. POCT is often accomplished through the use of transportable, portable, and handheld instruments (e.g., blood glucose meter, nerve conduction study device) and test kits (e.g., CRP, HBA1C, Homocystein, HIV salivary assay, etc.). Small bench analyzers or fixed equipment can also be used when a handheld device is not available—the goal is to collect the specimen and obtain the results in a very short period of time at or near the location of the patient so that the treatment plan can be adjusted as necessary before the patient leaves. Cheaper, faster, and smarter POCT devices have increased the use of POCT approaches by making it cost-effective for many diseases, such as diabetes, carpal tunnel syndrome (CTS) and acute coronary syndrome. Additionally, it is very desirable to measure various analytes simultaneously in the same specimen, allowing a rapid, low-cost, and reliable quantification. Therefore, multiplexed point-of-care testing (xPOCT) has become more important for medical diagnostics in the last decade. Many point-of-care test systems are realized as easy-to-use membrane-based test strips, often enclosed by a plastic test cassette. This concept often is realized in test systems for detecting pathogens. Very recently such test systems for rheumatology diagnostics have been developed, too. These tests require only a single drop of whole blood, urine or saliva, and they can be performed and interpreted by any general physician within minutes.....

Glucose Testing

Glucose Testing Glucose Testing is a important and vital part of a diabetics daily health care. Without testing, a diabetic can become sick because their glucose levels are not where they need to be. Glucose testing is done by using a glucose testing meter, which uses a glucose testing strip. Glucose Testing Meter Steps for Testing Glucose To test for glucose one must drop a sample of blood by placing on the strip. This is done by poking the skin with a needle called a lancet. The lancet pricks the finger which allows the sample of blood to flow right onto the glucose strip. Once the blood sample has made it on to the glucose strip, a device called a glucose meter is used to measure the glucose in the blood. In each test strip, there is a chemical called glucose oxidase. This glucose oxidase reacts with the glucose in the blood sample and is created into a acid called gluconic acid. This current is then able to read and determine how much glucose is in the sample of blood on the testing strip. The number is then relayed on the screen of the glucose testing meter. Blood Glucose Meters A glucose meter is used to determine the approximate concentration of glucose in the blood. The glu Continue reading >>

    For a while I was having really high morning readings. Then I figured out that my readings went up if I didn't eat for too long. So now I try to eat protein before going to bed at night and my numbers are back down to a reasonable range.
    I wish there were more options on the Diabetic Nutrition page for entering our BG range. I don't just do readings pre and post meals. I keep much closer track because I want to know what things cause spikes. I usually stay at between eighty and one hundred ten. Sometimes though I will spike up to 130 and above to 140. I need to know what causes these spikes so that I can control them. I think I need to be able to put in a time as well as the pre and post meals.

What is IMMUNE TOLERANCE? What does IMMUNE TOLERANCE mean? IMMUNE TOLERANCE meaning - IMMUNE TOLERANCE definition - IMMUNE TOLERANCE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Immune tolerance or immunological tolerance describes a state of unresponsiveness of the immune system to substances or tissue that have the capacity to elicit an immune response. It contrasts with conventional immune-mediated elimination of foreign antigens (see Immune response). Tolerance is classified into central tolerance or peripheral tolerance depending on where the state is originally inducedin the thymus and bone marrow (central) or in other tissues and lymph nodes (peripheral). The mechanisms by which these forms of tolerance are established are distinct, but the resulting effect is similar. Immune tolerance is important for normal physiology. Central tolerance is the main way the immune system learns to discriminate self from non-self. Peripheral tolerance is key to preventing over-reactivity of the immune system to various environmental entities (allergens, gut microbes, etc.). Deficits in central or peripheral tolerance also cause autoimmune disease, resulting in syndromes such as systemic lupus erythematosus, rheumatoid arthritis, type 1 diabetes, autoimmune polyendocrine syndrome type 1 (APS-1), and immunodysregulation polyendocrinopathy enteropathy X-linked syndrome (IPEX), and potentially contribute to asthma, allergy, and inflammatory bowel disease. Tolerance, however, also has its negative tradeoffs. It allows for some pathogenic microbes to successfully infect a host and avoid elimination. In addition, inducing peripheral tolerance in the local microenvironment is a common survival strategy for a number of tumors that prevents their elimination by the host immune system.

Glucose Screening And Glucose Tolerance Testing

Learn what these painless tests are, and why it's important to have them done during your second trimester. When is the test taken? Glucose screening is usually done between 24 and 28 weeks of pregnancy. If the test, which screens for gestational diabetes, reveals elevated levels of blood glucose (sugar), a glucose tolerance test is then given to confirm the gestational diabetes diagnosis. Who needs to take the test, and why? You should have a glucose screening during pregnancy if you are over 30, have a family history of diabetes, had a troubled earlier pregnancy or are obese. But even if you don't fit any of these criteria, your practitioner may still advise taking this safe and simple test, because about half of the women who develop gestational diabetes have no known risk factors. About 15 to 20 percent of women who take this screening will show abnormal levels of glucose and will be given the more involved (and more precise) glucose tolerance test. About 15 percent of the women given the second test will be diagnosed with gestational diabetes. Gestational diabetes can be controlled by diet, exercise or insulin. But if the elevated glucose levels remain undetected, the excess s Continue reading >>

    Hi everyone, I am new to the forum. I have been reading around diabeties for a litle while now and have come across articles that indicate some foods are worth investigating for the positive effects on blood sugars and hypertension. However, these articles never actually state amounts or how often they should be eaten. One presumes they are best eaten as close to their natural state as possible. But does anyone know how much cinnamon or how often you need to take it, for it to have an appreciable effect on blood sugars? Exactly how much beetroot or beetroot juice would be needed to bring your blood pressure down and thereby negate the need for medication? Has anyone got any evidence of these or any other foods that would have positive effects for diabetics?

    Don't bother with UK cinnamon, it has to be Cinnamomum Cassia which is contained in McCormicks cinnamon which I buy from the US from ebay. I put about 1 gram on my modified museli breakfast each day.

    Hello troika1 and welcome to the forum
    I take Cinnamon and other natural supplements to help lower blood sugar levels. They do seem to work reasonably well but none are a tenth as good as getting your diet sorted out. To really normalise blood sugar levels look to reduce the carbohydrates you are eating so drastically or cut out anything with sugar and then at least halve the amount of rice, pasta, potatoes, cereal, bread and any other flour based products. Replace the remaining rice, pasta and bread with the brown versions, Burgen soya bread is the best. If you do that you will be near enough following a similar diet to one the Swedish health system recommends. I followed it and normalised my levels in around 10 weeks. I did end up eating less carbohydrate than the Swedish diet recommended. You can read some more about the Swedish stuff on this thread
    and you can see the discussions we are having around Cinnamon and other things on this thread.
    Take care and keep asking questions
