Cholesterol Level Formula:
| From: | To: |
Total cholesterol (TC) is the sum of three main types of lipids in the blood: low-density lipoprotein (LDL), high-density lipoprotein (HDL), and very low-density lipoprotein (VLDL). It provides an overall measure of cholesterol levels in the body.
The calculator uses the cholesterol formula:
Where:
Explanation: This simple additive formula combines the three major cholesterol components to provide a comprehensive view of an individual's cholesterol profile.
Details: Monitoring total cholesterol levels is essential for assessing cardiovascular health risk. Elevated cholesterol levels are associated with increased risk of heart disease, stroke, and other cardiovascular conditions.
Tips: Enter LDL, HDL, and VLDL values in mg/dL. All values must be non-negative numbers. For accurate results, use recent laboratory test values.
Q1: What are optimal cholesterol levels?
A: Desirable total cholesterol is below 200 mg/dL. LDL should be below 100 mg/dL, HDL above 40 mg/dL for men and 50 mg/dL for women, and VLDL typically between 5-40 mg/dL.
Q2: How often should cholesterol be tested?
A: Adults should have cholesterol checked every 4-6 years. Those with risk factors or existing conditions may need more frequent testing.
Q3: What affects cholesterol levels?
A: Diet, exercise, weight, age, gender, genetics, and certain medications can all influence cholesterol levels.
Q4: Can I calculate TC if I don't have VLDL?
A: VLDL is often estimated as triglycerides divided by 5 when direct measurement isn't available.
Q5: What's the difference between LDL and HDL?
A: LDL is often called "bad cholesterol" as it contributes to plaque buildup, while HDL is "good cholesterol" that helps remove LDL from arteries.
