There is no line on the pregnancy test stick_Nothing shows on the pregnancy test stick

If there is no line on the pregnancy test stick, it is likely that the pregnancy test stick has expired. At this time, you can go to the pharmacy and buy another one. Generally speaking, the accuracy rate of pregnancy test sticks is relatively high, unless there is a problem with the pregnancy test stick itself. Pregnancy is a big deal. The sooner you know it, the better. At least you can prepare earlier. You can go to the hospital for a blood test at this time.

1. What if the pregnancy test stick does not show any result?

Although pregnancy test sticks can detect whether you are pregnant, I still want to give some tips to female friends who need to take pregnancy tests 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. If no control line appears within 5 minutes, it means the test is invalid or failed.

2. Do pregnancy test sticks have watermark lines?

The vast majority of pregnancy test products on the market use the colloidal gold method, which uses the double antibody sandwich principle to conduct qualitative or semi-quantitative testing of HCG in urine 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.

The watermark refers to the second line, the first line is just a reference line. The pregnancy test stick has one dark and one light color. You can vaguely see a little bit of red at the position of the second antenna, which is the watermark.

The pregnancy test stick will usually give results within five minutes. If it is left for half an hour, it will be inaccurate and meaningless. Besides, the pregnancy test stick will not be able to detect pregnancy twelve days after intercourse. Generally, the pregnancy test stick needs to wait five days after the menstruation is delayed to detect pregnancy.

You must master the correct method of using the pregnancy test stick. This is the prerequisite for everyone to use the pregnancy test stick. At the same time, you must correctly understand the measurement of the pregnancy test stick. Of course, it is generally recommended that you test in the morning, so that the accuracy rate will be improved. Sometimes the pregnancy test stick does not show pregnancy, it is very likely that you are not pregnant. Don't be discouraged, relax and it will be easier to conceive.
