summary

Recently, my cousin finally conceived a baby. I was very happy, but recently I often feel abdominal pain, sometimes anemia, and my face becomes very pale. I heard that this may be ectopic pregnancy. Now let me tell you how to check ectopic pregnancy with hCG.

How does hCG check ectopic pregnancy

First: the early diagnosis of ectopic pregnancy is mainly to detect hCG (human chorionic gonadotropin). Because hCG is a specific hormone secreted during pregnancy, β - hCG can be used to assist in the diagnosis of early unruptured ectopic pregnancy. The amount of hCG secreted by normal villi was very large, and the titer of hCG increased rapidly every day, rising by more than 66% every 48 hours. If the increase of β - hCG is more than 66% every two days, it can be diagnosed as intrauterine pregnancy.

Second: if the increase is less than 66%, ectopic pregnancy or intrauterine pregnancy dysplasia is very likely. After pregnancy, the increase of β - hCG in bleeding can be measured from the 9th to 11th day, and then the amount of β - hCG can be increased by 2 times every two days (even if there is threatened abortion, the increase rate of hCG will not change). For example, it's 234 today. If it's 450 the day after tomorrow, it can be considered as normal intrauterine pregnancy.

Third: comparison of other diagnostic methods: the positive predictive value of hCG normal rise excluding ectopic pregnancy is about 95%. Comparison of ultrasound results and hCG concentration can also estimate ectopic pregnancy. When hCG reaches 1000 UL, vaginal ultrasound should be able to identify intrauterine gestational sac. When hCG reaches 6500 UL, abdominal ultrasound can identify intrauterine gestational sac. If not, ectopic pregnancy should be suspected.

matters needing attention

Blood HCG has always been the main means to check whether pregnancy or not, and it also has good effect in checking ectopic pregnancy. By checking the amount of β - hCG secreted by villi, and also need to combine with a certain period of time, we can distinguish ectopic pregnancy.
