The level of human chorionic gonadotropin can be detected by a blood test 10 days after intercourse without contraception. After the fertilized egg is laid, i.e. about 7 days after ovulation, the syncytial trophoblast cells start to secrete human chorionic gonadotropin, and a blood test can indicate that the value is elevated and exceeds the normal range.
