The implementation of a serum P less than 5.0 ng/mL is important because it resolves the differential diagnosis of EP by enabling timely uterine curettage. Curettage with examination of curettings or documentation of falling hCG can be used to prevent unnecessary laparoscopies in patients undergoing spontaneous abortions and can make possible definitive diagnosis and medical treatment of EP completely eschewing anesthesia and surgery.
血清P低于5.0 ng/mL的实施很重要，因为它通过及时进行刮宫术解决了异位妊娠（EP）的鉴别诊断问题。刮宫并检查刮出物或记录hCG下降情况，可用于防止自然流产患者进行不必要的腹腔镜检查，并有可能对EP进行明确诊断和药物治疗，从而完全避免麻醉和手术。
