To assess the risk of developing a heart disease and to monitor its treatment.
As a screening test when no risk factors are present and to monitoring at regular intervals when risk factors are present. When high risk levels are present in the prior results and to monitor the effectiveness of treatment.
1. What is a low-density lipoprotein (LDL) test?
The low-density lipoprotein (LDL) test is used as part of a lipid profile to assess the risk of heart diseases and to monitor its treatment. LDL is not measured directly but is calculated from the results of total cholesterol, HDL and triglycerides. This calculation is accurate in most of the cases but becomes inaccurate when triglycerides are high (i.e., > 400 mg/dL). In such cases, LDL is to measured directly.
2. What is LDL-P test?
LDL-P test measures the number of LDL particles, rather than measuring the amount of LDL-cholesterol. The number of LDL particles, and their size, is an additional factor to consider when determining the risk for cardiovascular diseases.
3. What is the plan of treatment if lipid levels are unhealthy?
Lifestyle modifications are necessary to maintain healthy lipid levels. A diet low in saturated fat and trans unsaturated fats, avoiding smoking, controlling hypertension and diabetes, and moderate exercise. Drug therapy may be initiated on the basis of the results of the lipid profile.
4. How is LDL calculated?
Often laboratories use a formula called Freidewald's formula to calculate LDL. It the results of the parameters of Lipid Profile that are measured directly. The results are accurate only if triglycerides are < 400 mg/dL.
LDL cholesterol = Total cholesterol – ( HDL + triglycerides/5)
