Do patients need to be fasting for testing on the Cholestech LDX® System?
Patients do not have to be fasting for total cholesterol and HDL cholesterol testing. Triglycerides and glucose can increase markedly after eating. For accurate triglyceride and glucose results patients should be fasting for 9-12 hours before blood is drawn for testing. The triglyceride result is used in calculating the LDL cholesterol result so for accurate LDL cholesterol results the patient should also be fasting.
