What are the main methods for detecting ectopic pregnancy?

Ectopic pregnancy refers to a manifestation of pregnancy displacement. Therefore, it is not possible to detect ectopic pregnancy in time after the early stage. Therefore, we can choose some ectopic pregnancy examination methods to detect it. Next, let's learn about the knowledge of ectopic pregnancy in this regard.

1. Posterior fornix puncture: This is one of the examination methods for ectopic pregnancy. Since blood in the abdominal cavity is most likely to accumulate in the rectouterine pouch, even if the amount of blood is not large, it can be sucked out through posterior fornix puncture.

2. Pregnancy test: When the embryo survives or the trophoblast cells are viable, the syncytial cells secrete hCG, and the pregnancy test of patients with ectopic pregnancy may be positive. Since the hCG level in patients with ectopic pregnancy is lower than that in normal pregnancy, the general hCG determination method has a low positive rate. Therefore, this is also a major method for checking ectopic pregnancy.

3. Ultrasound diagnosis: In the early stage of tubal pregnancy, the B-ultrasound image of the patient with ectopic pregnancy can show an enlarged uterus, but the uterine cavity is empty, and there is a low echo area next to the uterus. This method of examination for ectopic pregnancy can see the sonographic characteristics of non-tubal pregnancy, and the possibility of corpus luteum in early ectopic pregnancy patients needs to be ruled out.

The above is a detailed description of the examination methods for ectopic pregnancy. I hope it can help everyone understand the knowledge of ectopic pregnancy and cure it in time. If you have other questions about ectopic pregnancy, you can contact our online experts to answer your questions.
