药物引起的血小板减少症并不常见。虽然已知药物可通过多种途径使血小板减少,但仍不完全清楚。若血小板减少到2万/毫米~3以下,一般认为是严重的。正常范围是15万～40万/毫米~3如红细胞未充分沉淀或血小板发生聚集,可造成计数偏低。血小板聚集可由于温度过低,用不适当的抗凝剂或接触凝血酶、二磷酸腺 Drug-induced thrombocytopenia is uncommon. Although drugs are known to reduce platelets in a number of ways, they are not fully understood. If thrombocytopenia to 20,000 / mm ~ 3 the following, generally considered to be serious. The normal range is 150,000 ~ 400,000 / mm ~ 3, such as inadequate precipitation of red blood cells or platelet aggregation, can cause the count low. Platelet aggregation can be due to the temperature is too low, with inappropriate anticoagulants or exposure to thrombin, diphosphate gland
