Lipid profile

This section does not Please help ( May 2020) ( The lipid profile typically includes: • • • • Using these values, a laboratory may also calculate: • • Cholesterol:HDL ratio The lipid profile tests are of 7 types: • Total lipids • Serum total cholesterol • serum HDL cholesterol • Total cholesterol/HDL cholesterol ratio • Serum triglycerides • Serum Phospholipids • Electrophoretic fractionation to determination percentage of • (a) Chylomicrons • (b) LDL • (c) VLDL • (d) HDL Procedure and indication [ ] Recommendations for cholesterol testing come from the Adult Treatment Panel (ATP) III guidelines, and are based on many large clinical studies, such as the [ citation needed] For healthy adults with no cardiovascular risk factors, the ATP III guidelines recommend screening once every five years. [ citation needed] In the pediatric and adolescent population, lipid testing is not routinely performed. However, the [ citation needed] Traditionally, most laboratories have required patients to fast for 9–12 hours before screening. However, studies have questioned the utility of Typically the laboratory measures only three quantities: total cholesterol; HDL; Triglycerides. From these three data LDL may be calculated. According to Friedewald's equation: • [LDL] = [Total cholesterol] − [HDL] − [Triglycerides] / 5 Other calculations of LDL from those same three data have been proposed which yield some significantly different results. VLDL can be defined as the total cholesterol that is ...
