Can hcg rule out ectopic pregnancy?

What is HCG?

HCG is a glycoprotein hormone secreted by the trophoblast cells of the placenta. When the fertilized egg implants, it extends branch tentacles and grabs the uterine wall. These tentacles are villi, which will form the early placenta. When the placenta is immature, these hairs will become more and attach to the membrane. Clinically, HCG levels are measured to understand embryonic development as one of the indicators for predicting pregnancy outcomes.

Can HCG rule out ectopic pregnancy?

1. The doubling time of HCG in early pregnancy is 1.4-2.2 days. We often say it is about 48 hours. Don't be nervous even if it does not double to 2 times the next day.

2. If the amount of HCG increases every two days,

3. If the pregnancy rate has not doubled or has not doubled well after reexamination, consider biochemical pregnancy or ectopic pregnancy. Ectopic pregnancy is often accompanied by obvious symptoms, such as low progesterone, abdominal pain, bleeding, etc.

The significance of HCG test:

1. Ectopic pregnancy: Irregular menstruation, positive HCG, non-reciprocal abdominal pain, vaginal bleeding, and syncope should alert you to the possibility of ectopic pregnancy, and can also be used to identify other acute abdominal diseases.

2. Threatened abortion: If HCG drops below 25000IU/L and gradually decreases, abortion may occur. During fetal protection treatment, if HCG continues to drop, it means that fetal protection is ineffective; if HCG continues to rise, it means that fetal protection is successful.

3. Incomplete abortion: If there is still placental tissue remaining in the uterus, the HCG test may still be positive; for complete abortion, the HCG test will change from positive to negative.

4. Trophoblastic cell tumor: Urine HCG 3 weeks after surgery

Through the above explanation, everyone understands that doubling of hcg on the second day can rule out ectopic pregnancy. But I think it is safest to go to the hospital for examination after pregnancy to rule out the possibility of ectopic pregnancy. Women of childbearing age with a history of ectopic pregnancy, fallopian tube inflammation, abdominal surgery, artificial abortion, etc. should be highly vigilant about ectopic pregnancy, keep in touch with the doctor, and closely observe the baby's condition.
