Patient's question:
Some say that Hcg being greater than 10 means pregnancy, while others say it needs to be in the thousands to confirm pregnancy. How should one interpret this? Does ectopic pregnancy cause menstruation?Doctor's answer:
Using hCG can also be configured to determine if it is an ectopic pregnancy, but it requires combining other testing methods for further careful examination to confirm. Additionally, it is necessary to continuously monitor the hCG values to make predictions. However, ectopic pregnancy does not have this characteristic that can serve as a basis for differentiation. If a woman becomes pregnant and it is an ectopic pregnancy, it is best to cooperate with an ultrasound examination to confirm the ectopic pregnancy.Can hCG values indicate ectopic pregnancy?
(1) Rate of increase: In normal early intrauterine pregnancy, the rate of increase in blood hCG is 1.4~2.2 days. In abnormal pregnancy (ectopic pregnancy, miscarriage), the rate of increase in blood hCG is 3~8 days.
(2) Comparison with other diagnostic methods: The positive predictive value of using hCG to rule out ectopic pregnancy is approximately 95%.
