Pregnancy can sometimes be unexpected. Its sudden visit sometimes catches many young parents off guard, with some delighted, some worried, and some at a loss. Many careless mothers may not know they are pregnant in a timely manner, but in fact, test strips are also a good tool. So, how many days does the test strip detect pregnancy? Let's learn about it together.
How many days did the test strip test for pregnancy
1. It can be tested within 7-10 days afterwards, of course, the longer the time, the more accurate it will be. On the 6th to 7th day after fertilization, when the trophoblast layer of the fertilized egg forms, a small amount of HCG (human chorionic gonadotropin) begins to be secreted, and the secretion continues to increase until the serum concentration reaches its peak at 8-10 weeks of pregnancy. Generally, early pregnancy testing can only detect HCG at a certain concentration 7-10 days after the start of HCG secretion.
2. The most important criterion for the quality of early pregnancy test strips is their sensitivity, not their timing. The optimal testing time for early pregnancy test strips is 18 days after the meeting of sperm and egg.
How to read pregnancy test paper
1. Some people take urine into small cups for delivery, then use a straw to suck a few drops into the drip window. After a few minutes, you can see a red line on the display window, one indicating no pregnancy and two indicating pregnancy. Some people also put urine into a cup and put the bottom of the test strip into the urine. After a while, the liquid can be seen dripping, showing a red line. The same one is missing, but there are two.
2. In order to improve accuracy, on the one hand, it depends on the quality of the test paper itself. Generally, there are no problems with buying it at a pharmacy. On the other hand, during testing, use morning urine and be careful not to contaminate the display window when dripping liquids, which may affect accuracy. If it is a direct immersion test paper, be careful not to let the urine level in the cup exceed the warning line on the test paper. If it exceeds, it will also affect the results. If you are concerned about inaccurate results, you can have a follow-up examination every three to five days.
Through the previous text, I believe everyone has understood the two issues of how many days the test strip measures pregnancy and how to read the pregnancy test paper. Pregnancy is a matter that requires caution and attention, and couples should also pay more attention to their physical condition, especially girls, and protect themselves. If a girl discovers that she may be pregnant, she must immediately use test strips or go to the hospital for examination to plan for the next step.
