As pregnancy tests, quantitative blood tests and the most sensitive urine tests usually detect hCG between 6 and 12 days after ovulation. However, it must be taken into account that total hCG levels may vary in a very wide range within the first 4 weeks of gestation, leading to false results during this period.
Doubling times for hCG are a good way to check whether a pregnancy is progressing normally until about six or seven weeks after your last menstrual period.
