Does a line on area C mean pregnancy?

It is very important to take contraceptive measures during sexual intercourse, otherwise an unexpected pregnancy may occur. The typical feature of an unexpected pregnancy is the delay of regular menstruation. At this time, you can use a pregnancy test stick or a pregnancy test paper for testing, but many people cannot correctly judge the displayed results. So, does a line in area C mean pregnancy? Let’s take a look below.

You have sex, your period is delayed, and if it is dry, then you are not pregnant. Pregnancy test sticks generally have the following results:

1. There are two red lines on the pregnancy test stick: one is located in the test area (T) and the other is in the quality control area (C). It is a positive result, indicating pregnancy.

2. A red line on the pregnancy test stick: Only a purple-red strip appears in the quality control area (C), and no purple-red strip appears in the test area (T). A negative result indicates that you are not pregnant.

3. One line on the pregnancy test stick is dark and the other is light: one line is in the test area (T) and is relatively light, while the other line is in the quality control area (C) and is darker. This is a weak positive result, indicating the possibility of pregnancy.

4. There is no red line on the pregnancy test stick: No purple-red strip appears in the quality control area (C), indicating an incorrect operation process or the reagent strip has deteriorated and damaged.

The results of pregnancy test sticks after pregnancy are not 100% accurate. If you want to confirm whether you are pregnant, it is recommended to go to a local hospital for blood tests, B-ultrasound and other auxiliary examinations to confirm. When looking at a pregnancy test stick, you must clearly identify the control line and the test line. If the control line does not appear, it means that the test is invalid or has failed.

How to check pregnancy with pregnancy test stick

The pregnancy (positive) result can be read after 1 minute (30 seconds at the fastest), which means that if two lines are clearly shown after 1 minute of testing, it indicates a pregnancy (positive) result and there is no need to wait for 3 minutes before reading.

The result of not being pregnant must be confirmed after 3 minutes. This is because in the early stages of pregnancy, the HCG hormone content in the urine is very low, and a weakly positive result may appear during the test. The weakly positive result may not be displayed after 1 minute. As the reaction time increases, it will take 3 minutes for two lines to appear. At this time, the appearance of two lines should still be interpreted as a pregnancy (positive) result. If there is still only one control line after 3 minutes, it can be judged as a not being pregnant (negative) result.

The results read after more than 5 minutes will have errors. This is because the reading within 5 minutes is used as the experimental basis for designing the product. The results read after more than 5 minutes or even longer are not clear. Some people may have false positive results. This result does not represent the actual situation.
