Fetal heartbeat visible on the scan; Serum hCG level ≥5000 IU/L; In cases of tubal ectopics, a laparoscopic salpingectomy is usually performed, removing both the ectopic pregnancy and the tube that it is implanted within.

Once the levels have reached at least 2,000, some type of development is expected to be seen in the uterus using high-resolution vaginal ultrasound.
