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.
If you use a home pregnancy test after an hCG injection, it is advisable to wait 20 days before interpreting the test as positive or negative. The best way to detect a pregnancy after an hCG injection or shot is the hCG beta blood test. The blood test is much more sensitive than an urine pregnancy test. The blood hCG test can detect a pregnancy as early as 10 days after fertilization with one caveat. You need two tests several days apart. If you are not pregnant, then the blood hCG numbers will be zero or they will decrease. If you are pregnant then they will rise.
