常做的早产检查如下：应检查宫颈松弛试验，阴道全景四维彩超，动态数字化子宫输卵管碘油造影,必要时行溶血试验，染色体，免疫，内分泌，三D腔镜等探查。不管是原发流产还是继发流产，均可一日确诊!诊断不清，治疗不灵，诊断不全，治疗没完!

　　The preterm tests that are often done are as follows: cervical relaxation tests should be checked, vaginal panoramic four-dimensional color ultrasound, dynamic digital hysterectomy, hemolytic tests when necessary, chromosomes, immunity, endocrine, tri-D endoscope and other explorations. Whether it is a primary miscarriages or secondary miscarriages, can be diagnosed one day! The diagnosis is not clear, the treatment is not effective, the diagnosis is not complete, the treatment is not over!
