LDL-P (LDL Particles) test measures the number of LDL cholesterol particles in the blood rather than the concentration of LDL cholesterol (LDL-C) measured by most current tests. The results of LDL-P test should be compared with the results of LDL-C test; when the results do not match (high LDL-P/normal LDL-C or normal LDL-P/high LDL-C), then, according to some authors, the LDL-P test results are considered a better predictor of the risk of cardiovascular disease (heart attack and stroke) than LDL-C results [29,37] . According to other authors, LDL-P test does not give better information about the coronary heart disease risk than total/HDL cholesterol ratio  .
A word of caution concerning the new home cholesterol tests now available at local pharmacies and through the Internet: Home cholesterol tests, such as the CholesTrak and First Check Home Cholesterol Test, are indeed faster than visiting your health care provider, but may not be very useful. The kits, which require the user to draw blood from a prick of the skin, measure only total cholesterol (not HDL, LDL and triglycerides individually)—interesting information that doesn't provide accurate information about your cardiovascular risk or much about the impact of diet or exercise on your cholesterol.
More About Hormone Levels
It is important to remember that with all women, hormone levels can very greatly. It is also important to mention that since the “normal” ranges vary greatly for some hormones (especially since each lab sets its own “normal” values for these hormones), some women with PCOS have hormone levels that appear within the “normal” range, but still suffer from symptoms and still might have PCOS. This is especially true with Testosterone , DHEAS, and LH levels. Unfortunately, many physicians are not familiar enough with PCOS to understand that even small changes in hormone levels can cause PCOS-related symptoms. If you have a Testosterone level of >40 ng/ml, DHEAS level of >200 ug/dl or a LH level that is two or three times that of your FSH level (LH and FSH levels should be roughly equal), seek the advice of a specialist since there is still a good possibility you might have PCOS.
