1. What is the LDL Cholesterol Formula?

The Friedewald formula estimates LDL cholesterol from total cholesterol, HDL cholesterol, and triglyceride measurements. It provides a calculated LDL value without requiring direct measurement, which is useful for routine screening.

2. How Does the Calculator Work?

The calculator uses the Friedewald formula:

\[ LDL = TC - HDL - \frac{TG}{2.2} \]

Where:

\( LDL \) — Low-density lipoprotein cholesterol (mmol/L)
\( TC \) — Total cholesterol (mmol/L)
\( HDL \) — High-density lipoprotein cholesterol (mmol/L)
\( TG \) — Triglycerides (mmol/L)

Explanation: This formula estimates LDL cholesterol by subtracting HDL and VLDL (estimated as TG/2.2) from total cholesterol.

3. Importance of LDL Calculation

Details: LDL cholesterol is a major risk factor for cardiovascular disease. Monitoring LDL levels helps assess cardiovascular risk and guide treatment decisions, with optimal levels being ≤2.6 mmol/L.

4. Using the Calculator

Tips: Enter total cholesterol, HDL cholesterol, and triglycerides in mmol/L. All values must be valid positive numbers. The calculator will estimate your LDL cholesterol level.

5. Frequently Asked Questions (FAQ)

Q1: Why is 2.6 mmol/L considered optimal?
A: LDL levels ≤2.6 mmol/L are associated with lower cardiovascular risk, especially in high-risk individuals or those with existing heart disease.

Q2: When is the Friedewald formula not accurate?
A: The formula is less accurate when triglyceride levels are high (>4.5 mmol/L) or when LDL is very low. Direct measurement is preferred in these cases.

Q3: How often should cholesterol be checked?
A: Adults should have cholesterol checked every 4-6 years, or more frequently if risk factors exist or if previous results were abnormal.

Q4: What factors affect LDL levels?
A: Diet, exercise, weight, genetics, medications, and certain medical conditions can all influence LDL cholesterol levels.

Q5: How can I lower my LDL cholesterol?
A: Lifestyle changes like a heart-healthy diet, regular exercise, and maintaining a healthy weight can help. Medications may be needed for some individuals.
