How to check for ectopic pregnancy?

In order to effectively confirm whether it is an ectopic pregnancy and reduce the various threats to women's health as much as possible, it is important to understand the correct examination methods, such as hcg measurement, progesterone measurement, and ultrasound diagnosis, which are all effective methods to check whether it is an ectopic pregnancy.

1. HCG determination

It is currently an important method for early diagnosis of ectopic pregnancy.

2. Progesterone determination

The serum P level in ectopic pregnancy is low, but it is relatively stable at 5 to 10 weeks of gestation, and a single measurement has a great diagnostic value. Although there is overlap between normal and abnormal pregnancy serum P levels, making it difficult to determine the absolute critical value between them, a serum P level lower than 10 ng/m1 (radioimmunoassay) often indicates abnormal pregnancy, with an accuracy rate of about 90%.

3. Ultrasound diagnosis

Type B ultrasound examination is particularly commonly used for the diagnosis of ectopic pregnancy, and vaginal ultrasound examination is more accurate than abdominal B-type examination.

4. Diagnostic curettage

When ectopic pregnancy cannot be ruled out, a diagnostic curettage can be performed to obtain the endometrium for pathological examination. However, the endometrial changes in ectopic pregnancy are not characteristic and may be manifested as decidual tissue, highly secretory phase with or without A-S reaction, and various secretory and proliferative phases. Changes in the endometrium are related to whether the patient has vaginal bleeding and the duration of vaginal bleeding. Therefore, the diagnosis of ectopic pregnancy based solely on diagnostic curettage has great limitations.

5. Posterior fornix puncture

Posterior uterine fornix puncture is widely used to assist in the diagnosis of ectopic pregnancy. Blood can often be drawn out and does not coagulate after being placed, and contains small blood clots. If no fluid is removed, the diagnosis of ectopic pregnancy cannot be ruled out.
