The reason why the pregnancy test stick shows a line

Nowadays, most people will doubt whether they are pregnant if their menstruation is delayed for a long time. Under normal circumstances, they will not go to the hospital for examination first. Basically, everyone will test it at home with a pregnancy test stick to see if there is one line or two lines. But some people have never used a pregnancy test stick, so they don’t know how to look at it. So let’s study how to use the pregnancy test stick correctly and what it means when a line appears on the pregnancy test stick.

The main principle of the pregnancy test stick is to detect the HCG value, which is the value of human chorionic gonadotropin one month after pregnancy. It is a hormone secreted by pregnant women and exists in urine and blood. It usually appears in urine a few days after pregnancy, but due to the small amount, it is not easy to test it at the beginning, and it will not become increasingly obvious until 10 to 14 days. Therefore, it is recommended to test 10-14 days after the menstrual period is delayed, and try to use the first urine in the morning for testing.

Test results:

Two red lines appear at the same time. If two purple-red lines appear on the stick at the same time, and the test area is clearly visible. A positive result indicates pregnancy.

There is only one red line. Only a purple-red strip appears at the control line C, and there is no purple-red strip at the test area T, which is negative, indicating that you are not pregnant: one dark and one light color appear. The marking in the test area T is lighter, and the color of the control line C is darker, which is a weak positive phenomenon, indicating the possibility of pregnancy: there is no red line on the pregnancy test stick. If you use a new pregnancy test stick, even if you use a relatively poor quality 2 yuan one, there will generally be no problem. If no purple-red band appears, it may be that you are incorrect or there may be a problem with the pregnancy test stick. In another case, if only the test area T is displayed and the control line C is not displayed, it also means that the result is invalid. Invalid: The test result will be checked in about 5 minutes, so you must check it at any time within 5 minutes. It will be extremely inaccurate if you exceed the time. If the display exceeds 5 minutes, the test may be invalid or failed.

How to use: Tear open the aluminum foil bag along the notch before use and take out the pregnancy test stick:

Put on the disposable plastic film gloves included in the box, hold the handle of the pregnancy test stick tightly with your thumb, and tilt the urine suction hole downward. Note that the observation side of the pregnancy test stick should be facing downward. Please refer to the instructions for details:

Aim at the urine suction hole on the side of the pregnancy test stick and urinate, allowing the urine to pass through the urine suction hole and maintain the urine collection time for 1 to 2 seconds.

The accuracy of pregnancy test sticks is still very high. If your menstruation is delayed, you can use a pregnancy test stick to test. If the pregnancy test stick shows a single line within 8-10 days after the delayed menstruation, then you don’t need to worry too much. Just pay attention to regulating your endocrine system. If two lines are detected using the pregnancy test stick after delaying, you need to go to the hospital for a definitive examination. If one line is dark and the other is light, you need to do another test after two days.
