The diagnosis of anemia is an important aspect of the practice of hematology. The first step is to decide whether the patient is, in fact, anemic. Unless earlier blood counts are available, and they often are not, the physician must make his or her decision on the basis of the population distribution of hemoglobin values. How likely is it that the patient's hemoglobin value lies below the normal distribution; that is, "the lower limit"?
贫血的诊断是血液学实践的一个重要方面。第一步是确定患者是否真的患有贫血。除非有更早的血常规结果（但通常没有），医生必须根据血红蛋白值的人群分布来做出判断。患者的血红蛋白值低于正常分布，即“下限”的可能性有多大？
