The structure of the ? chain is basically similar to that of luteinizing hormone (LH), and it is easy to Cross-reaction occurs, so medical judgment of pregnancy is generally based on ? as the standard. When first pregnant, the HCG content is much lower than that of HCG. When HCG is only 50-100, HCG has often reached about one or two thousand. If you use pregnancy test paper at this time, you often cannot get the result, but if you use ovulation test paper, you can find a strong positive result. Therefore, using ovulation test paper can determine whether you are pregnant earlier than using early pregnancy test paper.

Continue to test the ovulation test paper after the strong positive of the ovulation test paper turns weak. Don’t be afraid of wasting the ovulation test paper. Keep testing until it is negative.

Cross-reaction is easy to occur, so medical judgment of pregnancy is generally based on ? as the standard. Because HCG and LH overlap, sometimes ovulation test strips also respond to early pregnancy. Therefore, before the early pregnancy test paper, the ovulation test paper had already detected early pregnancy.

2. Why is it said that early pregnancy test paper is not as early as ovulation test paper?

Because the current early pregnancy test paper basically tests HCG, and the content of HCG is far lower than that of ovulation test paper. , when HCG is only 50-100, HCG has often reached about one or two thousand. The early pregnancy test paper is determined by HCG, and the cross-reaction is determined by HCG, so the ovulation test paper will be positive earlier than the early pregnancy test paper.

3. Can pregnancy test strips also detect ovulation?

It is impossible. The manufacture of early pregnancy test strips takes this into consideration, and it eliminates the occurrence of cross-reaction. Therefore, it can only detect HCG.

4. If the ovulation test paper detects a weak yang, does it necessarily mean that you are pregnant?

If the ovulation test paper detects a weak yang, it does not necessarily mean that you are pregnant.

Many sisters have used personal experience to prove the fact that ovulation test strips can detect early pregnancy.
