Lupus Anticoagulant Profile Blood Test

Also Known As

Dilute Russell Viper Venom Test, DRVVT, LA, LA Sensitive PPT, Lupus Anticoagulant Panel, Lupus Inhibitor, Modified Russell Viper Venom Test, MRVVT, PTT-LA 

The Purpose of a Lupus Anticoagulant Test

Despite the name, this anticoagulant test isn’t actually used to determine if you have lupus. The test looks for lupus antibodies (which were first found in people with the autoimmune disorder, although anyone can produce these antibodies). They disrupt normal blood cell function, raising the risk of blood clots. A lupus anticoagulant blood test helps investigate the cause of a blood clot and can evaluate a prolonged partial thromboplastin time (PTT), which means blood takes longer to clot than normal. There are other circumstances when it’s useful to take a lupus anticoagulant test. For instance, these antibodies may be a factor if a woman experiences multiple miscarriages, and testing will help her decide if she needs to see specialists while trying to conceive. A test may also diagnose an autoimmune disorder called antiphospholipid syndrome, which is responsible for blood clotting.

What Does the Lupus Anticoagulant Lab Test Measure?

This testing looks for the presence of lupus anticoagulants in the blood and measures those levels.

Who Should Take a Lupus Anticoagulant Test?

People who have issues with blood clotting, or have clots that take longer than usual to form, may need testing for lupus anticoagulants, especially if there is no known reason for the problem. Women with multiple miscarriages may also want to be tested to make sure they don’t have lupus antibodies.

Lupus Anticoagulant Panel Preparation

Ask your doctor if you should stop taking any anticoagulant medication, as that may affect the results.

Lupus Anticoagulant Blood Test Results

A positive test result means lupus anticoagulants have been detected in your blood. Generally, typical levels should fall between 20 to 39 grams per liter. Patients on heparin or heparin substitute (such as hirudin, danaparoid, or argatroban) anticoagulation therapy may have false-positive results for lupus antibodies, but those on warfarin (Coumadin®) anticoagulant therapy should not. Higher-than-normal levels may require further testing.
