What is the range of hcg value for ectopic pregnancy

All pregnant women need to pay attention to the occurrence of ectopic pregnancy, because if it causes rupture and heavy bleeding, it will directly threaten life. Ectopic pregnancy can actually be understood through the hcg value range. If the increase in hcg every two days is less than 66%, then the probability of ectopic pregnancy is very high.

1. Generally, the HCG radioimmunoassay value of a normal person is less than 3.1. If it exceeds 5, the possibility of conception can be considered. If it exceeds 10, pregnancy can be basically confirmed. HCG can rise to greater than 2500IU/L 35-50 days after pregnancy. Early diagnosis of ectopic pregnancy is mainly based on the detection of blood HCG (human chorionic gonadotropin). Because HCG is a specific hormone secreted during pregnancy, HCG can be used to assist in the diagnosis of early unruptured ectopic pregnancy.

2. The amount of HCG secreted by normally developed villi is very large, and the daily titer continues to rise rapidly, increasing by more than 66% every 48 hours. If it is greater than 66%, it can be diagnosed as an 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%. (If it is difficult to confirm with HCG, blood progesterone can also be used for auxiliary diagnosis. It is generally recognized that the blood progesterone level of patients with ectopic pregnancy is low. Therefore, it can be used as one of the early diagnosis methods.

3. The critical value is 63nmol/L. Further B-ultrasound examination can be performed, especially "vaginal ultrasound" examination is very helpful for diagnosing ectopic pregnancy. After a woman becomes pregnant, an increase in HCG can be detected in her blood starting from the 9th to 11th day, and the amount of β-HCG can double every two days thereafter (even if there is threatened miscarriage, the rate of HCG increase will not change). For example, if today's value is 234, if the test result the day after tomorrow is around 450, it can be considered as normal intrauterine pregnancy. If the rate of increase is slow for two consecutive times, it indicates an ectopic pregnancy or abnormal development of the embryo.

4. For example, if the HCG value is 10 today, 15 the day after tomorrow, and 17 two days later, such HCG value is definitely abnormal, and the success rate of preserving the pregnancy is extremely low. If the HCG value continues to drop significantly, it is best to perform a uterine curettage even if the fetal heart rate is detected by B-ultrasound, as this indicates that the fetus is actually brain dead.
