I believe most mothers are familiar with pregnancy test strips. At first, when they thought they might be pregnant, they used them for testing. However, I believe that most mothers are not very clear about the principle of pregnancy test strips. Today, Baike will talk to you and share with you about pregnancy test strips.
1. What is the principle of pregnancy test strips
Pregnancy test strips determine whether a girl is pregnant by detecting the level of HCG in her urine. HCG refers to human chorionic gonadotropin, which is a protein produced by the placenta during pregnancy and can be excreted from urine. Therefore, pregnancy can be determined by detecting its presence or amount.
2. Analysis of the results of pregnancy test strips
If only the control line appears, it means that the girl is not pregnant. If the test result is weakly positive, it means that the test line is weaker than the control line, indicating a chance of pregnancy. It is necessary to have another pregnancy test the next day. If the result is positive, it means congratulations, you are a mother. If it is invalid, it means that the experiment has failed.
3. What is the accuracy of pregnancy test strips
Due to the fact that this is purchased by women themselves and tested at home without professional guidance, the accuracy rate is generally between 50% and 75%. Unless this experiment is conducted in a laboratory under the guidance of a doctor, the accuracy rate can reach 100%. For women who are nervous about pregnancy, errors are inevitable.
So although the function of pregnancy test strips is significant, the accuracy may still decrease due to different pregnancy testing conditions. To accurately determine whether you are pregnant, it is better to go to the hospital for a detailed examination.
