Clinical Significance. Lipid Panel with Reflex to Direct LDL - The Lipid Panel with Reflex to Direct LDL panel includes evaluation of total cholesterol, HDL-cholesterol, triglyceride (TG), LDL-cholesterol (calculated), cholesterol/HDL ratio (calculated), and non-HDL cholesterol; direct LDL-C measurement will be performed at additional cost if the TG level is >400 mg/dL.Coagulation is the formation of a blood clot (or thrombus), and is essential to haemostasis. Haemostasis is the body's physiological response to stop or prevent bleeding.The coagulation process is characterised by a cascade where one event sets off another and so on.
