What this test is
The value comes from the Friedewald equation, which works well when triglycerides are not too high. Above a certain triglyceride level the calculation becomes unreliable and a direct measurement is preferred.

LDL- Cholesterol (Calculated)
Calculated LDL uses a formula based on total cholesterol, HDL and triglycerides. It is a widely used, economical approach.
What it is used for, and who should test
- Assessing heart risk in routine lipid panels
- Tracking treatment when compared with previous results using the same method
- Initial screening before deciding whether more testing is needed
Sample and preparation
- Sample
- 2-3 mL of blood in a serum tube
- Preparation
- Fast for 8-12 hours, since food-related triglyceride spikes distort the calculated LDL.

Frequently asked questions about this test
Why can results differ between laboratories?
The calculation depends on the triglyceride value, so high triglycerides or differences in sample timing can change the result compared with a direct measurement.
Should I switch to the direct method?
Consider it if triglycerides are above the threshold or a more precise value is needed. Our staff can advise the right option for you.
How should I prepare for LDL- Cholesterol (Calculated)?
Fast for 8-12 hours, since food-related triglyceride spikes distort the calculated LDL.
How long do results take?
About 45 min, depending on the laboratory workload that day. Our staff will confirm the collection time when you are served.
