How soon can a pregnancy test strip detect pregnancy?

Hello, A pregnancy test strip can detect pregnancy as early as 7–10 days after conception; however, accuracy improves with time. The principle underlying home pregnancy tests is the detection of human chorionic gonadotropin (hCG). hCG is produced by the placenta and begins appearing in urine shortly after implantation—typically within several days of conception—becoming reliably detectable by 7–10 days. However, because hCG levels are still relatively low at this stage, it is generally recommended to wait until 10–14 days after conception for optimal test accuracy. I hope this information is helpful. Wishing you a happy and healthy life!
