What is this test?
This entry is a procedure identifier rather than a standard blood measurement. It documents that LDL apheresis was performed, a treatment in which blood passes through a machine that removes low-density lipoprotein (LDL) and then returns the treated blood to the body.
Why might I need this test?
LDL apheresis may be considered for selected people with very high LDL cholesterol, including some patients with familial hypercholesterolemia or cholesterol levels that remain elevated despite appropriate treatment. A specialist determines whether the procedure is appropriate.
How is the test performed?
During the procedure, blood is removed through a catheter and circulated through an apheresis system. The system separates the blood components, removes LDL, and returns the remaining blood through another catheter. The identifier is added to the medical record to show that the treatment was performed.
How do I prepare for the test?
Preparation depends on the apheresis center's instructions and your overall treatment plan. Do not stop prescribed medicines unless your care team tells you to. Ask whether fasting or any special medication timing is required, and tell the staff about bleeding problems, low blood pressure, allergies, or recent medication changes.
Reference range
Optimal: <100 mg/dLN/A
Fasting for 12-14 hours preferred. Water is permitted. Avoid alcohol for 24 hours before the test.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
The identifier confirms that an LDL apheresis procedure occurred; it does not provide a numerical LDL result or indicate that LDL is high or low. Response to treatment is assessed through follow-up LDL measurements and the overall clinical picture. The need for additional sessions is determined by the treating specialist.
