PREGMATE pregnancy tests detect human pregnancy hormone (HCG) in urine. This hormone is produced by the cells of the embryo that will later form the placenta. The level of hormone starts to increase from its basal level of less than 5 miu/ml directly after implantation and doubles each 48 hours during the first weeks of pregnancy. If you want to test as early as possible, but want to make sure you’re getting the most accurate result, test the day your next period is supposed to begin - you will have a 99% chance of getting an accurate reading.
The average implantation time is 9 days past ovulation. It takes 2-3 days for the embryo to make enough hcg hormone for a home pregnancy test to detect. That means the majority of women will not get a positive result until 11 days past ovulation.
