HCG value of 8.5U/L can not determine whether pregnancy, need to be combined with the number of days of menopause, symptoms, imaging and laboratory tests to determine.
HCG refers to human chorionic gonadotropin, which is mainly produced by gestational trophoblast cells, and can be produced by pregnancy, gestational trophoblastic diseases, germ cell tumors, and other malignant tumors such as lung, adrenal and liver tumors.
In normal pregnancy, HCG is produced when the fertilized egg is deposited, i.e., when the trophoblast layer of the fertilized egg is formed on the 6th day after ovulation, and peripheral blood HCG can be detected about 1 day later, and then it rises by 1 times every 1.7 to 2 days, reaching about 100 U/L on the 14th day after ovulation.
In non-pregnant women, the HCG value should be <3.1 U/L. Normally, a blood concentration of >25 U/L is considered positive for pregnancy. Therefore, an HCG value of 8.5 U/L cannot determine whether a woman is pregnant or not, but may be a very early pregnancy, biochemical pregnancy, ectopic pregnancy, etc. It is necessary to combine with the number of days after menopause, symptoms, imaging and laboratory tests to determine the overall situation.
If a woman’s HCG value is 8.5U/L, it is recommended that she consult a doctor in time to clarify the cause and carry out targeted treatment.
