What does it mean when there is a red line on the pregnancy test stick?

If there is only one red line on the pregnancy test stick, it usually means you are not pregnant. If you want to use a pregnancy test stick to confirm whether you are pregnant, you need to use two bars on the pregnancy test stick to indicate a symptom of pregnancy. If your menstrual cycle is normal, you can use the pregnancy test stick to check whether you are pregnant about ten days after having sex. However, pregnancy test sticks have errors. It is best to go to the hospital for a blood test, as the test results are more accurate.

There is a red line in the C area of ​​the pregnancy test stick

A red line in zone C of the pregnancy test stick may mean you are not pregnant, or it may mean that the hormone concentration does not meet the requirements of the test paper. You can use different brands of early pregnancy test strips to test your morning urine at the same time, such as Tyencon, David, etc. to see whether the results displayed by different test strips are consistent. This will help to determine whether you are pregnant.

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 (HCG) 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.

Although pregnancy test sticks can detect whether you are pregnant, I still want to give female friends who need to take pregnancy tests a few tips to improve the accuracy of pregnancy test sticks. 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.

How to use pregnancy test stick

1. Tear open the aluminum foil bag along the notch and take out the pregnancy test stick when using.

2. Put on the disposable plastic film gloves included in the box, hold one end of the handle of the pregnancy test stick tightly with your thumb, and tilt the end with the urine suction hole downward. Note that the observation side of the pregnancy test stick should face downward and the plum blossom pattern should face upward.

3. Urine towards the urine suction hole on the side of the pregnancy test stick, allow the urine to pass through the urine suction hole, and maintain the urine collection time for 1 to 2 seconds (please note that urine should not wet the observation window when collecting urine! Otherwise, the pregnancy test stick will become invalid).

4. Then turn the pregnancy test stick over so that the observation window is facing upwards, and continue to hold the pregnancy test stick at an angle. When you see purple-red liquid crawling across the observation window, purple-red lines will appear on the observation window within 1 minute. The pregnancy result can be read after 1 minute, and the non-pregnancy result must be confirmed after 3 minutes. Results read after 5 minutes are invalid. Urine samples collected at any time are suitable for pregnancy test kits. If you are in early pregnancy, morning urine is best. Results read after 5 minutes are invalid. This is because the interpretation within 5 minutes is used as the experimental basis for designing products. The results of interpretation after more than 5 minutes or even longer are not clear. Some people may have false positive results, and this result does not represent the actual situation.
