hCG (human chorionic gonadotropin) levels typically become detectable in blood and urine tests around 10-14 days after conception. This hormone is produced by the placenta shortly after the embryo attaches to the uterine lining. For most accurate results, it is advisable to take a pregnancy test at least one to two weeks after a missed period.
