What does the red color on the pregnancy test stick mean?

In the past, when condoms were not yet popular, people would go to the hospital to get an IUD or a sterilization to prevent pregnancy and childbirth. However, for women, IUD insertion can easily cause gynecological diseases, and for men, sterilization can easily lead to loss of sexual function or decreased labor force, so generally speaking, men will not get sterilized. After all, men are the backbone of the family. Now, once there are signs of pregnancy, people will buy a pregnancy test stick to test it first. However, some people don’t understand what it means if there is red color?

The principle of pregnancy test stick testing: The pregnancy test stick is a type of in vitro diagnostic (IVD) product. The so-called test is to use the pregnancy test stick to detect human chorionic gonadotropin in urine. HCG is a troponin secreted by the placenta of pregnant women. It is distributed throughout the body with the blood, thereby acting on target organs. A certain concentration of HCG is also present in the urine. Currently, most pregnancy test products on the market use the colloidal gold method, which conducts qualitative or semi-quantitative detection of HCG in urine based on the double antibody sandwich principle to determine whether a woman is pregnant. It is worth noting that such pregnancy test products are not 100% accurate, and certain diseases may also cause increased HCG concentrations in the body, resulting in false positive results.

How long does it take to detect pregnancy? In fact, it just means how long it will take to know if you are pregnant and how long it will take to test it out. Experts tell us that generally from the 7th to 10th day of pregnancy, a specific hormone, referred to as HCG, can be detected in the urine of pregnant women. The early pregnancy test strips on the market can detect whether you are pregnant the fastest. Generally, it can be detected 7 days after sleeping together. You can also go to the hospital for testing, which is also through urine chorionic villus detection, usually one week after sleeping together. You can also test whether you are pregnant one week after your period is delayed next month, which is more accurate. Therefore, the correct answer to how long it takes to detect pregnancy is that it can be tested after about a week of sleeping together.

First, try to use the first urine in the morning for testing, because hormone levels are easiest to detect at this time. Do not drink too much water to increase urine production, as this will dilute hormone levels. Some medications may affect the results of the test, so be sure to read the label instructions carefully.

If there are two red lines on the pregnancy test stick, it means you are pregnant. If there is one line, then you are not pregnant. The color represents the concentration of hCG. Light color means low hCG concentration. Generally, the first urine in the morning 10-14 days after intercourse is the most accurate. Darker colors are more accurate. Generally, vomiting will start after about one month or two months of pregnancy, and it varies from person to person. Some people may not vomit at all during their entire pregnancy.

It is recommended that if menstruation does not resume on schedule, you can use a test strip to check whether you are pregnant and observe carefully.

So when using a pregnancy test stick, you should pay attention to a few points: first, use the first urine when you wake up in the morning, take out the test paper and wait for five minutes to roughly know whether you are pregnant. If there is only one red line, you are not pregnant; if both lines are red (one of them may be lighter in color), you are pregnant. If you are still worried, you can go to the hospital for a check-up.
