Description: The Low-Density Lipoprotein Cholesterol (Direct) Test (LDL test) may be used to determine risk for developing heart disease. The LDL test may be used to measure LDL levels in a non-fasting specimen or when triglyceride values are too high (over 400mg/dl) to properly calculate LDL. Turnaround time for the LDL test is typically 1 business day.
Requirements: The LDL test has no fasting requirements. LDL may decrease with acute illness, accident or surgery or increase during pregnancy. It is recommended that those patients wait 6 weeks before testing.
