Test Information
Total cholesterol, which is made up of triglycerides as well as the high-density (HDL) and low-density lipoprotein (LDL) cholesterol fractions, is shown in the fasting lipid profile. Triglycerides, HDL cholesterol, total cholesterol, and LDL cholesterol are all tested, and LDL cholesterol is estimated using a formula. Due to the requirement of this computation, LDL-cholesterol values can only be obtained in a fasting sample. According to recent research, elevated non-fasting triglyceride levels are linked to an increased risk of cardiovascular disease (CVD) and atherosclerosis. Ratios that indicate the likelihood of getting CVD are generated from these findings. Dietary restrictions or cholesterol-lowering medications may help to lower the risk of CVD. A specialist lipid clinic should be consulted in cases of complicated lipoprotein abnormalities, such as familial hypocholesterolemia.
Clinical Indications
• F/H of thrombotic events, such as CVD, CVA, or others
• Diagnosis and monitoring of primary or secondary hyperlipidaemia (caused, for example, by hypothyroidism, the nephrotic syndrome, or drug use, such as beta-blockers, anti-retroviral therapy, thiazide diuretics, and certain antipsychotic and antidepressants).
• Monitoring Hypertension, Obesity and Patients with Familial Hypercholesterolemia.
