Test Info
Lipid Panel with Ratios - This panel measures serum cholesterol and triglyceride (TG) levels. It includes evaluation of the LDL/HDL ratio (calculated) cholesterol/HDL-C ratio (calculated) HDL-C LDL-C (calculated) non-HDL-C (calculated) total cholesterol and TG. Comprehensive lipid assessment aids in evaluating cardiovascular disease (CVD) risk and the likelihood of an ischemic event. It is also useful for the prevention and management of atherosclerotic disease and diagnosis of metabolic syndrome [1]. CVD is the leading cause of death in the United States. Individuals with high LDL-C and TG levels are at elevated risk for developing CVD and having an ischemic event [23]. The American Heart Association recommends that Americans aged 20 and above have their lipid levels tested every 4 to 6 years. Children should have their cholesterol tested for the first time between ages 9 and 11 and again between ages 17 and 21. Testing should start earlier if there is a family history of high cholesterol [4]. This panel reports a calculated LDL/HDL ratio in addition to all the components included in Lipid Panel Standard (test code 7600). High LDL/HDL ratio may be a stronger predictor of coronary heart disease than LDL and HDL alone in patients with hypertriglyceridemia [5]. Treatment with N-acetyl cysteine for acetaminophen overdose may generate a falsely low result for cholesterol [6]. Venipuncture immediately after or during administration of the painkiller metamizole (dipyrone) may also lead to falsely low results for cholesterol [7]. Note: Any or all individual tests from a panel can be ordered separately. The results of this test should be interpreted in the context of pertinent clinical and family history as well as physical examination findings.
