Dyslipidemia
Diagnosis of Dyslipidemia
Blood tests to measure cholesterol levels Levels of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides—the lipid profile—are measured in a blood sample. Because consuming food or beverages may cause triglyceride levels to increase temporarily, people must fast at least 12 hours before the blood sample is taken. When lipid levels in the blood are very high, special blood tests are done to identify the specific underlying disorder. Specific disorders include several hereditary disorders (primary dyslipidemias), which produce different lipid abnormalities and have different risks. Margarines made primarily from liquid oil (squeeze or tub margarines) and those that contain plant stanols or sterols, unlike stick margarines, are healthier substitutes for butter for people who need to limit their butter intake.
