Ectopic pregnancy cannot be diagnosed by a urine test, but the measurement of HCG in urine or blood is crucial and necessary for the early diagnosis of ectopic pregnancy. The level of HCG in the body is lower in ectopic pregnancies than in intrauterine pregnancies, but more than 99% of patients with ectopic pregnancies are HCG positive, except for a very small number of stale ectopic pregnancies that can show a negative result, so a positive test through urine HCG indicates that a woman is pregnant. Ectopic pregnancy, ultrasound is indispensable to help clarify the location and size of the pregnancy, transvaginal ultrasound is more accurate than transabdominal ultrasound, ectopic pregnancy typical ultrasound sonographic characteristics of the uterine cavity did not detect the gestational sac, the uterine parietal detection of abnormal hypoechoic area, and see the yolk sac, embryonic buds and primordial cardiac tube pulsation can be determined to be an ectopic pregnancy. Ectopic pregnancy should also be highly suspected if a mixed echogenic zone is detected in the paracentral region and there is a free dark area in the uterorectal fossa, even though no embryonic buds or fetal heartbeat are seen.
