Each pregnancy resulted in spontaneous abortion in the second trimester. The patient has a history of joint pain, chronic migraines, and recurrent poorly defined, macular skin rashes. She also reports episodes in which her fingers become pale and cold, and then redden. She is sexually active with her husband and does not use contraceptives. The patient works as a landscape architect. Her mother has a history of endometriosis. The patient takes a daily prenatal multivitamin and occasionally sumatriptan. She appears tired. Temperature is 36.5C 97.7F, pulse is 65min, and blood pressure is 11065 mm Hg. Examination of the hands shows two ulcerations on the tip of the right index finger and multiple tiny hemorrhages under the nails. There is a purple reticular rash on both calves. Which of the following is most likely to confirm the diagnosis?? A: Test for cryoglobulins, B: Hysteroscopy, C: Factor V Leiden functional testing, D: Test for anticardiolipin antibodies, E: Blood smear for sickle cells,  <response>: This patient has a history of recurrent second trimester miscarriages, which raises suspicion for an underlying autoimmune or thrombophilic disorder. She also has symptoms suggestive of Raynauds phenomenon, skin rashes, and joint pain. The description of purple reticular rashes on the legs could indicate livedo reticularis, which is associated with antiphospholipid antibody syndrome. The presence of anticardiolipin antibodies would confirm the diagnosis of antiphospholipid antibody syndrome, which can lead to recurrent pregnancy loss. Cryoglobulins, Factor V Leiden, and sickle cell tests are less likely to be relevant in this clinical scenario. Hysteroscopy may identify uterine structural abnormalities but would not confirm the suspected diagnosis.D: Test for anticardiolipin antibodies
