Understanding cholesterol testing and How to Prepare for It
What Is a Cholesterol Test?
A cholesterol test is a procedure aimed at measuring cholesterol levels in the blood. The test results provide an indicator of the likelihood of developing heart diseases. If the test reveals high cholesterol levels, you can take steps to lower them, thereby reducing the risk of future heart problems.
cholesterol levels (Readings):
The table below illustrates the levels of High-Density Lipoprotein (HDL) "good" cholesterol, Low-Density Lipoprotein (LDL) "bad" cholesterol, and total cholesterol:
| Cholesterol Type | Desired Level (mg/dL) | Average Level (mg/dL) | Abnormal Level (mg/dL) |
|---|---|---|---|
| Total Cholesterol | Less than 200 | 200-240 | Over 240 |
| HDL Cholesterol | Less than 45 | 35-45 | More than 45 |
| LDL Cholesterol | Less than 130 | 130-160 | More than 160 |
| The ratio of total cholesterol to HDL | Less than 3 | More than 4 |
Cholesterol readings vary from person to person depending on their health status, medical evaluation, and influencing factors such as:
- Smoking
