What blood tests require fasting is a very broad question that can be answered on a test by test basis at www.labtestportal.com with details on fasting requirements as well as locations on where you can actually get the blood testing performed.
The question of what blood tests require fasting can go in all different directions and will be addressed with the most commonly ordered blood tests. You can always go to labtestportal.com and search on your test that you may have a question for and get a direct answer.
For the most commonly ordered blood tests we will go with the CBC. The Complete Blood Count with Differential (CBC) screens for blood abnormalities including red and white blood cells, hemoglobin and platelets. The CBC is used as a screening test to check for possible disorders such as anemia, infection, and many other diseases. With a CBC you do not need to be fasting for this blood test. To correlate what blood tests require fasting to the second most ordered group of test, we go with the comprehensive metabolic profile. The Comprehensive Metabolic Panel (CMP) is a group of 14 tests that gives you doctor information about the current status of your kidneys, liver, and electrolyte and acid/base balance as well as of your blood sugar and blood proteins. The tests measured include Glucose, Calcium, Albumin, Total Protein, Sodium, Potassium, CO2, Chloride, BUN, Creatinine, ALP, ALT, AST, and Bilirubin. What blood tests require fasting with the comprehensive profile you should use the answer of you definitely should be fasting.
As we continue on the most commonly ordered laboratory tests and what blood tests require fasting we move to the lipid profile. Lipid profile is a group of tests that are often ordered together to determine risk of coronary heart disease. The tests that make up a lipid profile are tests that have been shown to be good indicators of whether someone is likely to have a heart attack or stroke caused by blockage of blood vessels (hardening of the arteries). The measured tests are Cholesterol, total; High-Density Lipoprotein (HDL) cholesterol; Low-Density Lipoprotein (LDL) cholesterol (calculation); Triglycerides; Very Low-Density Lipoprotein (VLDL) cholesterol (calculation). With a lipid profile, you definitely should be fasting.
Along the same lines of having a healthy heart, the C-reactive protein test is commonly ordered. C-Reactive Protein (CRP) test is a blood test that measures the amount of a protein called C-reactive protein in your blood. C-reactive protein test measures general levels of inflammation in the body. High levels of CRP are caused by infections and long-term diseases. The test can help in monitoring illnesses such as cancer of the lymph nodes (lymphoma), diseases of the immune system, painful swelling of the blood vessels in the head and neck, rheumatoid arthritis, swelling and bleeding of the intestines (inflammatory bowel) or bone infection. With the C-reactive protein test, you should be fasting.
What blood tests require fasting can go on through a test directory of thousands. For men and hormones the 2 most commonly ordered hormones are Cortisol and Testosterone. Total Testosterone is a steroid hormone from the androgen group and is primarily secreted in the testes of males, although small amounts of testosterone are also secreted by the adrenal glands. Testosterone is the principal male sex hormone and an anabolic (help builds up lean tissues) steroid.
In men, testosterone plays a key role in the development of male reproductive tissues such as the testis and prostate as well as promoting secondary sexual characteristics. In addition, testosterone is essential for health and well-being as well as the prevention of osteoporosis. On average, an adult male produces about ten times more testosterone than an adult female, but females are more sensitive to the hormone. Cortisol is the primary hormone secreted by the adrenal gland which has a broad spectrum of physiological effects, ranging from supporting blood pressure and promoting normal circulation to helping the body to defend itself against outside stress. Cortisol is also important in regulating the body’s glucose and fat metabolism. It is a catabolic hormone, which in excess, promotes the breakdown of lean body mass and the accumulation of body fat. For both of these the question of what blood tests require fasting is answered by both of these do not require fasting.
I think it’s safe to say that we can go on and on with the question of what blood tests require fasting. The answer to what blood tests require fasting can go on forever and is as long as there are tests out there. The important thing to understand is that there is a resource you can turn to for an answer as well as a service that can test you on the blood test you inquired about at the online lab test service of www.labtestportal.com.
