The literature states that asymptomatic microscopic hematuria (AMH) is a sensitive indicator of underlying pathology and deserves investigation. However, studies to date have been done on urological outpatients and, because of referral and sampling bias, the findings may not be applicable to a family practice population. The positive predictive value of AMH may be very low in a family practice. The recommended investigations are invasive, expensive, and cause morbidity and mortality. Further studies must examine the significance of AMH in the general population. Such studies would help to identify at risk patients and, perhaps, allow investigations to be tailored to these patients, while the physician maintains a high degree of suspicion and keeps a watchful eye on the others.
文献指出，无症状性镜下血尿（AMH）是潜在病理的敏感指标，值得进行调查。然而，迄今为止的研究都是针对泌尿科门诊患者进行的，由于转诊和抽样偏差，这些发现可能不适用于家庭医学人群。在家庭实践中，AMH 的阳性预测值可能非常低。推荐的检查具有侵袭性、昂贵，并且会导致发病率和死亡率。进一步的研究必须检查 AMH 在普通人群中的意义。此类研究将有助于确定高危患者，也许可以使医生根据这些患者的情况调整检查，同时保持高度警惕并密切关注其他患者。
