It is used to help determine whether a prolonged APTT is due to a specific inhibitor an antibody against a specific coagulation factor or to a non-specific inhibitor like the lupus anticoagulant. Also high alpha-1 low albumin high alkaline phosphate crp lvl 31 high absolute neutroslymphocseosinos.

What does it mean if lupus anticoagulant is positive. Thrombosis in a vein or artery of the person Recurrent miscarriages in a woman An unexplained prolonged PTT test ie. Lupus anticoagulants were so-named because they were first found among patients with lupus but LA testing is not used to diagnose the autoimmune disorder and LA are frequently absent in people with lupus.

The time it takes in seconds for a persons blood sample to clot in a test tube after reagents are added to it.

Lupus anticoagulant is a protein that increases the risk of developing blood clots in both the veins and arteries.

Positive lupus anticoagulant test results indicate the patients blood will clot poorly excessively or in a way that causes other dangerous complications. If one screening test one mixing test and one confirmatory test are positive and there is no evidence for a factor inhibitor or.
