Human chorionic gonadotropin 430 U/L may be 30-40 days pregnant.
Human chorionic gonadotropin (hcg) is produced by trophoblast cells and begins to rise on day 6 after fertilization and implantation, and can be detected in serum on day 7, with concentrations greater than 25 U/L at a positive gestation, greater than 100 U/L on day 30 of gestation, and greater than 2,000 U/L on day 40 of gestation. human chorionic gonadotropin 430 U/L may be 30 to 40 days pregnant.
It peaks at 8-10 weeks of gestation and ranges from about 50,000 to 100,000 U/L, after which it begins to decline and returns to nonpregnant levels postpartum. Serum hcg is a more sensitive indicator for determining early pregnancy, but it is generally not used to determine the specific weeks of pregnancy, and the number of days of pregnancy needs to be determined by the last menstrual period or ultrasound.
If you have regular menstrual periods, you can calculate the number of days of pregnancy according to your last menstrual period. If you have irregular menstrual periods, it is recommended that you go to the hospital for clarification.
