Are ovulation tests accurate?

The principle of ovulation test paper is to predict whether pregnancy will occur at the optimal time by measuring the level of HCG (human chorionic gonadotropin) in a woman's body. HCG is produced by a fertilized egg, which usually combines and gradually grows in a woman's body. During ovulation, a woman’s HCG levels peak and remain there for a period of time. Therefore, by measuring HCG levels, you can predict whether you will get pregnant at the optimal time.

Its accuracy is affected by many factors, including measurement method, test time, woman's menstrual cycle, etc. In addition, some people may be allergic to or have errors in test paper. Therefore, it is recommended that when using ovulation test paper, you should use products of reliable brands as much as possible and read the instructions carefully before testing.

Overall, while an ovulation test is not 100 percent accurate, it is still a useful tool that can help women predict whether they will get pregnant at the optimal time.
