1. What is LDL Cholesterol?

LDL (Low-Density Lipoprotein) cholesterol, often called "bad cholesterol," is a type of lipoprotein that carries cholesterol to tissues and arteries. High levels of LDL cholesterol are associated with increased risk of cardiovascular disease.

2. LDL Conversion Formula

The conversion formula between mmol/L and mg/dL units:

This conversion factor is based on the molecular weight of cholesterol and is standardized for clinical use.

3. Importance of LDL Measurement

Details: LDL cholesterol measurement is crucial for assessing cardiovascular risk, guiding lipid-lowering therapy, and monitoring treatment effectiveness in patients with dyslipidemia.

4. Using the Calculator

Tips: Enter LDL cholesterol value in mmol/L units. The calculator will automatically convert it to mg/dL using the standard conversion factor of 38.67.

5. Frequently Asked Questions (FAQ)

Q1: Why are there different units for LDL measurement?
A: Different countries use different measurement systems. The United States typically uses mg/dL, while many other countries use mmol/L.

Q2: What are optimal LDL cholesterol levels?
A: Optimal LDL levels are generally below 100 mg/dL (2.6 mmol/L) for most adults, and below 70 mg/dL (1.8 mmol/L) for high-risk patients.

Q3: How often should LDL be measured?
A: Adults should have their cholesterol checked every 4-6 years. Those with risk factors or existing heart conditions may need more frequent testing.

Q4: Are there limitations to LDL measurement?
A: Direct LDL measurement is more accurate than calculated LDL, especially when triglycerides are elevated (>400 mg/dL or 4.5 mmol/L).

Q5: Can LDL levels fluctuate?
A: Yes, LDL levels can vary due to diet, exercise, medications, and other factors. Consistent fasting measurements provide the most reliable results.
