Also known as: Fasting lipid profile (total cholesterol, HDL cholesterol, triglycerides, and LDL cholesterol).
What is it? A blood test that measures the total cholesterol, HDL and LDL cholesterol levels, and triglyceride levels in the bloodstream.
Why is this test performed? To assess the risk for the development of coronary artery disease, the leading cause of death among people with diabetes in the U.S. It is also used to diagnose dyslipidemia, a condition characterized by the high triglyceride and cholesterol levels that can be caused by diabetes, particularly poorly controlled diabetes.
How frequently should this test be performed? The ADA recommends that a fasting lipid panel be performed at diabetes diagnosis, at an initial medical evaluation and/or at age 40 years, and periodically thereafter. If you are working with your physician to control lipid levels through medication or diet, testing may be done more frequently. However, the American Association of Clinical Endocrinologists/American College of Endocrinology (AACE/ACE) recommend that a fasting lipid profile be obtained during an initial assessment, each follow-up assessment, and annually as part of the cardiac-cerebrovascular-peripheral vascular module.
What is the "normal" range for results? Cholesterol levels vary by medical history, gender, age, ethnicity, and geographic region, but the National Cholesterol Education Program recommends an average target total cholesterol of under 200 mg/dl and triglyceride values of approximately 150 mg/dl or less.
NCEP guidelines also call for HDL (or good) cholesterol of at least 40-60 mg/dl and LDL (or bad) cholesterol of 129 or less. High-risk patients, which includes those with diabetes, should keep LDL at less than 100 mg/dl. The ADA recommends that people with diabetes keep triglycerides under 200 mg/dl, HDL cholesterol over 40 mg/dl in men and 50 mg/dl in women, and LDL cholesterol under 100 mg/dl.
In 2004, the NCEP issued new guidelines for patients considered at "very high risk." Patients are considered at very high risk if they already have cardiovascular disease plus diabetes, are smokers, have poorly controlled high blood pressure, have a history of heart attack, or have the metabolic syndrome. These patients may be treated to achieve a target LDL level of 70 mg/dl or less.
What do abnormal results mean? Moderately elevated triglyceride levels can indicate diabetes, but can also be caused by a host of other problems, including kidney and liver disease and alcoholism. High serum cholesterol levels can be triggered by poor dietary habits, pancreatitis, hypothyroidism, lipid disorders, and certain kidney and liver diseases. High LDL levels reflect an increased risk of coronary artery disease. Low HDL levels are indicative of cardiovascular risk. HDL is "good" cholesterol and high levels are desired. Elevated HDL levels may point to early liver disease, but can sometimes be found in healthy individuals.

As I mentioned in an earlier post, one of the benefits that made it cost-effective for me to go with the real healthcare (HSA) plan rather than the phony (HRA) plan is that my company is now covering "preventative" medicines at $0 copay. The formulary for these, as stated by CVS/Caremark (my pharmacy benefits provider), covers all test strips, lancets, and control solutions. I dutifully get my doctor to write up prescriptions for all of my testing needs, submit...
