Would you consider thrombophilia testing in a pregnant patient with VTE?

I would not check antiphospholipid antibodies in a pregnant woman with thrombosis unless she had a history of autoimmune disease or other concerning findings. However, if it were checked, I would make sure that it is a true positive. DOACs often cause a false positive LAC. I have had patients with false positives even up to 2 weeks after stopping.

I would request lupus anticoagulant and anticardiolipin antibody and if positive, repeat in 8-12 weeks and that will impact what to do after delivery. She will be on Lovenox during pregnancy, but she is at risk after and would need to know what to give, Warfarin vs DOACs.
