Can ovulation test strips detect early pregnancy? Generally speaking, we do not recommend using ovulation test strips to detect early pregnancy because its accuracy is very low. The principle of using ovulation test strips to test early pregnancy is that HCG has two chains, α and β. The structure of the α chain is basically similar to LH and fsh, and is prone to cross-reaction. Therefore, in medicine, β is generally used as the standard for judging whether pregnancy occurs. Because HCG and LH cross, ovulation test strips sometimes also react to early pregnancy. So before the early pregnancy test paper, the ovulation test paper had already detected early pregnancy.

In fact, ovulation test strips are not accurate in detecting early pregnancy. The absence of a weak positive result on the ovulation test strip does not mean that you are not pregnant, because cross-reaction is not inevitable. Therefore, although many women want to use ovulation test strips to detect early pregnancy, given its low accuracy, we do not recommend using ovulation test strips to detect early pregnancy.

Why can I use ovulation test strips to detect pregnancy?

Why can ovulation test strips be used to detect pregnancy? When a woman becomes pregnant, her body produces a specific hormone - human chorionic gonadotropin (hCG). hCG has two chains, α and β. The structure of the α chain is basically similar to that of luteinizing hormone (LH), and is prone to cross-reaction. When the LH detected by the ovulation test paper cross-reacts with the hCG released after the fertilized egg implants, the ovulation test paper will show a positive reaction, indicating the possibility of early pregnancy. Therefore, ovulation test strips can be used to detect pregnancy, but the accuracy rate of ovulation test strips is very low and is generally not recommended.
