1. What is Total Cholesterol?

Total cholesterol is a measurement of the total amount of cholesterol in your blood, which includes HDL (high-density lipoprotein), LDL (low-density lipoprotein), and VLDL (very low-density lipoprotein) cholesterol. In Canada, cholesterol levels are measured in millimoles per liter (mmol/L).

2. How Does the Calculator Work?

The calculator uses the standard Canadian formula:

\[ Total\ Cholesterol\ (mmol/L) = HDL\ (mmol/L) + LDL\ (mmol/L) + (Triglycerides\ (mmol/L) / 2.2) \]

Where:

\( HDL \) — High-density lipoprotein cholesterol (mmol/L)
\( LDL \) — Low-density lipoprotein cholesterol (mmol/L)
\( Triglycerides \) — Triglyceride level (mmol/L)

Explanation: The formula calculates total cholesterol by summing HDL, LDL, and VLDL cholesterol (estimated as triglycerides divided by 2.2).

3. Importance of Cholesterol Measurement

Details: Monitoring total cholesterol levels is crucial for assessing cardiovascular health. High cholesterol levels can increase the risk of heart disease and stroke, while balanced cholesterol levels contribute to overall cardiovascular wellness.

4. Using the Calculator

Tips: Enter your HDL, LDL, and triglyceride values in mmol/L as reported on your blood test results. All values must be non-negative numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are healthy cholesterol levels in Canada?
A: Generally, total cholesterol below 5.2 mmol/L is considered desirable, 5.2-6.2 mmol/L is borderline high, and above 6.2 mmol/L is high.

Q2: Why is the formula different in Canada?
A: Canada uses the metric system and reports cholesterol levels in mmol/L rather than mg/dL used in some other countries. The conversion factor of 2.2 for triglycerides is standard in Canadian calculations.

Q3: When should cholesterol be tested?
A: Adults should have their cholesterol checked every 4-6 years, or more frequently if they have risk factors for heart disease.

Q4: How can I improve my cholesterol levels?
A: Lifestyle changes including a heart-healthy diet, regular exercise, maintaining a healthy weight, and avoiding tobacco can help improve cholesterol levels.

Q5: Should I fast before a cholesterol test?
A: For a full lipid profile including triglycerides, fasting for 9-12 hours is typically recommended. Follow your healthcare provider's instructions.
