For example, a coagulation assay for the detection of LA and an ELISA for the detection of anti-phospholipid antibodies or cofactors like anti-CL or anti-b2GPI are recommended. Future testing may require a panel of tests. Physicians should interpret the results of the APS tests in light of the patient’s history, physical findings, and other diagnostic procedures.
