If you are taking aspirin will it affect the anticardiolipen blood test? If so how long do you need to avoid aspirin. Designer16

No, aspirin won't affect it.

[Hidden]

Aspirin will not affect any of the three blood tests which look for antiphospholipid antibodies: the anticardiolipin, the lupus anticoagulant and the anti-beta2-glycoprotein1.

The only real problem for APS patient is when you need the lupus anticoagulant blood test and you are already taking warfarin.
