A history of multiple cytopenias such as leukopenia, lymphopenia, anemia, or thrombocytopenia may suggest SLE, among other etiologies, such as medication-related cytopenias. Leukopenia and, more specifically, lymphopenia are common in SLE; this, coupled with immunosuppression, may predispose persons with SLE to frequent infections.

Anemia is occasionally overlooked in young menstruating women, and a history of lymphopenia may be overlooked. Thrombocytopenia may be mild or part of a full thrombotic thrombocytopenic purpura (TTP)–like syndrome or antiphospholipid antibody syndrome. A history of recurrent early miscarriages or a single late pregnancy loss may be clues to lupus or isolated antiphospholipid antibody syndrome. [94]
