Ovulation test paper early pregnancy white board

Generally speaking, it is not recommended to use ovulation test strips to detect early pregnancy because its accuracy is very low. The principle of using ovulation test strips to detect early pregnancy is that HCG has two chains, α and β. The structure of the α chain is similar to that of LH and FSH, and it is easy to produce cross-reactions. Therefore, β is generally used as the standard for judging whether a woman is pregnant in medicine.

Because HCG and LH cross each other, sometimes ovulation test strips can also reflect the early stages of pregnancy. Therefore, before the early pregnancy test paper, the ovulation test paper has already detected the early stage of pregnancy. In fact, ovulation test strips are not accurate in detecting early pregnancy. The absence of a weak positive result on the ovulation test paper does not mean that you are not pregnant, because cross-reaction is not certain. Therefore, although many women want to use ovulation test strips to detect early pregnancy, their accuracy is not high.

What is the reason for the deviation of ovulation test strips?

1. Perhaps many women have used their real experience to confirm the fact that ovulation test strips can detect the early stages of pregnancy. However, it should be noted that a weak positive result with an ovulation test strip does not necessarily mean that you are pregnant.

2. The main reason is that ordinary people ovulate once a month, and the highest LH value only appears once before the ovulation period of each month. In addition, the LH level generally remains at the bottom for a long time without much change. Therefore, under normal circumstances, the LH rise should not be detected more than ten days after ovulation. However, some people's LH level is always high, and there is always a weak positive LH after the ovulation period. Some people sometimes have abnormal LH fluctuations when their period is approaching. Therefore, if you judge that you are pregnant based on a weak positive test on the ovulation test paper, you may make an incorrect judgment.

Therefore, pregnant women need to clearly understand the difference between early pregnancy test strips and ovulation test strips. Although ovulation test strips can sometimes detect early pregnancy conditions, the situation is not certain. Therefore, if you want to check whether you are pregnant, it is recommended to buy an early pregnancy test paper for testing, and then go to a reliable hospital for a blood test to confirm.
