This test measures LDL cholesterol directly. It can be useful when the clinician wants a measured value rather than an estimate from the lipid panel.

Understanding the test
Also called Bad (LDL) Cholesterol
A direct measurement may help when a calculated LDL is difficult to interpret, including particular triglyceride patterns. Previous results can help assess response to treatment.
The clinician may choose direct LDL when the usual calculation is less reliable.
An earlier LDL measured by a comparable method helps show response across time.
Before your sample
Arrange the instructed overnight fast with plain water only. Tell the clinician about recent illness or a change in lipid treatment so direct LDL is compared under similar conditions.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.
Smart Report
24 hoursLaboratory turnaround
The laboratory reports the cholesterol carried within LDL particles. A clinician determines the significance of that concentration in the context of personal cardiovascular risk.

LDL describes the cholesterol carried by one group of particles. Triglycerides, HDL and cardiovascular history help determine what that value means for you.
Changing what you eat and being physically active can help lower LDL. Whether that is enough depends on your starting level and cardiovascular risk. Many people with inherited high cholesterol also need prescribed treatment.
Most often it means statins or other lipid-lowering treatment are working as intended. Without treatment, a low LDL can reflect an overactive thyroid, malnutrition or malabsorption, advanced liver disease, or a recent severe illness or major surgery. Rare inherited conditions can also keep LDL very low lifelong.
