Human chorionic gonadotropin (hCG) is produced by trophoblastic tissue and it appears around the 8-9th day after ovulation where fertilization has occurred, or around the 4th day after conception.
In a 28 day cycle with ovulation occurring at day 14, hCG can be detected in urine or serum in minute quantities around day 23, or 5 days before the expected menstruation. Its function includes facilitation of implantation as well as maintenance and development of the corpus luteum.
The hormone concentration doubles approximately every 2 days and peaks between concentration of 50,000 mIU/ml. Concentrations as high as 100,000 mIU/ normal subjects, hCG in urine provides an early indication of pregnancy.
