What tests are needed for habitual miscarriage?

The examination of habitual miscarriage is as follows:

1. Check for internal genital malformations

1. Hysterosalpingography (HSG): Hysterosalpingography is a sensitive and special method for diagnosing uterine malformation. Uterine malformation can be determined based on whether the shape of the uterine cavity is abnormal or filled with defects. If the cervical caliber is greater than 6mm, it is helpful to diagnose cervical insufficiency.

2. Ultrasound examination: Ultrasound is not as good as hysterosalpingography, but it is important for the diagnosis of abnormal uterine shape. If ultrasound examination and hysterosalpingography are used together, it can help identify and diagnose septate uterus and bicornuate uterus; ultrasound examination can determine the number, size and location of uterine fibroids.

3 Magnetic resonance imaging: Although it is costly, it plays a big role in determining genital malformations.

4 Laparoscopy and hysteroscopy: Both can directly observe the external morphology of the uterus and the condition of the uterine cavity, and can identify uterine malformations and their types. Hysteroscopy can also diagnose uterine adhesions and provide a certain degree of treatment. Laparoscopy can also diagnose and treat pelvic lesions, such as pelvic adhesions, endometriosis, etc.

5. Cervical dilator examination: When the No. 8 cervical dilator can be extended to the internal os of the cervix without difficulty, the cervix is ​​incompetent.

2. Examination of pathogen infection

Urine and cervical mucus culture to understand whether there is microbial infection. Pathogen infection is also the cause of recurrent miscarriage. Cervical secretion mycoplasma, chlamydia, β-hemolytic streptococcus, etc. TORCH detection of toxoplasma, rubella virus, cytomegalovirus, herpes virus immunoassay and other pathogenic microorganism antibody detection are of little significance unless the medical history indicates chronic infection. Pathological examination should be performed after miscarriage.
