After having sexual intercourse, if a woman wants to know if she is pregnant, she can use early pregnancy test strips after 14 days for pregnancy testing. However, early pregnancy test strips must use morning urine in order for the test results to be accurate. Some women are very puzzled about this and wonder why morning urine is necessary for early pregnancy? Regarding this issue, the editor will discuss it with everyone below.
Early pregnancy test strips must be tested with morning urine because the principle of early pregnancy test strips is to detect the content of HCG in urine. HCG, a hormone, is formed by the combination of egg and sperm after sexual intercourse in women. After the fertilized egg returns to the uterus and implants, it is secreted by the trophoblast cells of the placenta and first appears in the blood. It is excreted into the urine as the blood increases. At first, the amount is not large, and it will not become obvious until 14 days later before testing can be carried out.
So the concentration of HCG in urine is sufficient to detect it, and morning urine is the time when the HCG concentration is the highest in a day and has not been diluted with water, so the detection result is the most accurate. The specific detection method is to prepare the morning urine, take out the early pregnancy test strip, immerse the white end into the urine, and pay attention to the urine volume not exceeding the MAX line on the strip. After holding for 5 to 10 seconds, take it out and lay it flat for one minute to know the result.
If there is only one red line in the control area C and no red line in the detection area T, it means that the woman is not pregnant. If red lines appear in both the C and T areas, it means that the woman is pregnant. If the red line in the C area is deep and the red line in the T area is shallow, it means that the woman may be pregnant. It is recommended to recheck and confirm after one week. If there is no red line in the C area, it means that the test strip may have expired or the operation method may have been incorrect.
