How does hcg rule out ectopic pregnancy?

Once women have an ectopic pregnancy, after a certain period of time, the vagina will begin to bleed irregularly and there will be obvious abdominal pain symptoms. At this time, it is necessary to go to the hospital for examination in time to rule out ectopic pregnancy. The best way is to do an ultrasound examination. Today's B-ultrasound examination function is very powerful and can usually clearly tell whether an ectopic pregnancy has occurred. Of course, there are many other ways to help rule out ectopic pregnancy.

How does hcg rule out ectopic pregnancy?

Early diagnosis of ectopic pregnancy is mainly based on the detection of blood HCG (human chorionic gonadotropin). Normally developed villi secrete a large amount of HCG, and the daily titer continues to rise rapidly, increasing by more than 66% every 48 hours. If the amount of HCG increase every two days is greater than 66%, it can be diagnosed as intrauterine pregnancy; if the increase is less than 66%, there is a high possibility of ectopic pregnancy or intrauterine pregnancy hypoplasia. For ectopic pregnancy, due to the thin muscle layer of the fallopian tube and poor blood supply, the HCG secretion is very low. The daily appreciation is less. The increase in 48 hours was less than 50%.

HCG is a specific hormone secreted during pregnancy, so HCG can be used to assist in the diagnosis of early unruptured ectopic pregnancy. When the increase in HCG is less than 66%, there is a possibility of ectopic pregnancy, which should be paid attention to.

How much progesterone can rule out ectopic pregnancy

How much progesterone is needed to rule out an ectopic pregnancy? Generally speaking, a progesterone value higher than 20 NG/ML can rule out ectopic pregnancy. However, progesterone testing alone cannot be used as a basis for excluding ectopic pregnancy. This indicator only provides an indirect judgment indicator. In the early stages of conception, when B-ultrasound cannot provide accurate detection, progesterone testing can be used to rule out ectopic pregnancy. If the progesterone level is lower than 20NG/ML, you should pay attention and wait a week or two to go to the hospital for an ultrasound examination. If a gestational sac is seen in the uterus and there is no obvious cystic object outside the uterus, the possibility of ectopic pregnancy can be ruled out.

How long does it take to rule out an ectopic pregnancy?

If you have an ectopic pregnancy, there will be some abnormal reactions, such as vaginal bleeding or lower abdominal pain around 6 to 8 weeks of pregnancy. These are all early symptoms of ectopic pregnancy. If a pregnant woman does not show these symptoms within 6 to 8 weeks, she can preliminarily judge that she has a normal pregnancy. About 45 to 60 days after amenorrhea, you can go for an ultrasound examination. If the gestational sac is in the uterine cavity, the possibility of ectopic pregnancy can be ruled out. At this time, pregnant mothers can relax, maintain a positive and healthy attitude, pay attention to their diet and nutrition, and have regular prenatal checkups.
