Lipid profile is a commonly performed lab test performed to detect abnormalities in blood cholesterol and its components. Deranged values often suggest cardiovascular (heart disease) risk.
Who should do it & how often?
- In children, this test is not routinely performed. Some organization assess it once between 9 to 11 years of age to rule out any abnormality.
- Healthy adults (without any heart diseases) should do it at-least once in 5 years.
- People with known heart diseases, lifestyle diseases or with any lipid profile abnormalities should perform it more often (at-least once in a year).
One needs to fast for minimum 10 to 14 hours before conduction of the test. Water is allowed. Alcohol consumption must be avoided a day before the test.
Components of lipid profile:
1. Total cholesterol: Components such as HDL, LDL, VLDL make up total cholesterol.
2. Triglycerides: It is again a type of fat in blood. In excess amount it increases risk of diabetes and heart diseases.
3. LDL (Low Density Lipoprotein): It is also known as ‘bad cholesterol’ as it accumulates inside the blood vessels if it exceeds beyond the limit and increases the risk of heart diseases
4. HDL (High Density Lipoprotein): It is known as ‘good cholesterol’ as it is heart friendly. It prevents excessive build up of bad cholesterol.
5. VLDL (Very Low Density Lipoprotein): It is a derived fraction and calculated based on triglyceride levels.
Normal values may vary slightly from lab to lab depending upon the reagents and the used.
|Total Cholesterol||200 mg/dL|
|Triglycerides||Less than 150 mg/dL|
|LDL||Less than 130 mg/dL|
|HDL||Males: More than 40 mg/dLFemales: More than 50 mg/dL|
|VLDL||Less than 40 mg/dL|
