What the number means, why it moves on a protocol, and how it sits with related markers.

What it is

LDL is the cholesterol that builds plaque. On a protocol it can drift up while HDL drifts down, which is why the ratio between them is worth reading.

The range

How to read the lab range

Labs quote under 100 mg/dL (2.6 mmol/L) as optimal and up to 130 (3.4) as near optimal. Targets depend on your other risk factors, which is a conversation for your doctor.

Questions people ask

Is LDL of 130 bad on TRT?

It is borderline for anyone, and it reads worse next to a low HDL and a high hematocrit. The ratio, ApoB and the change since the last test add context.

How fast do lipids move after a dose change?

Within a few weeks, HDL usually faster than LDL.
