Lupus Anticoagulant Test on anticoagulant therapy?

[HumayunJ]

Hello all,

I am on anticoagulant therapy and intend to test for LAC. I have read over the internet that it might give false positive. If this is true, what should I do as I have an active clot under treatment.

Thanks.

HI this can be the case, however there are three tests so do the others also:

Lupus anticoagulant.

Anti-cardiolipin.

Beta-2 glycoprotein I.

Also give a clear medical history of yourself and any relatives with autoimmune disease, miscarriages/still births, or early heart attacks or strokes.

If you are on Xarelto just wait for 24 hours and it should have cleared.

This is true. I recently saw my heamotologist and he explained they couldn't test for lupus because I was on warfarin which would interfere with the results. Why are you intending to test? - surely your doctor or specialist knows you are on anticoagulants or haven't you told them? A very risky move.

If you must have the test speak to whoever is going to test as they need all your medical history to interpret the results.
