Pregnancy tests are used by dipping the side with the arrow in the urine and observing the results displayed on the other side. It is generally used as a way to test whether a woman who has stopped menstruating is pregnant or not. First of all, pregnancy test strips are used to detect HCG levels in urine. Before using it, you should look at the outer packaging,and use it only if the outer packaging is intact and undamaged. It also depends on the expiration date, if the expiration date is exceeded, the accuracy of the test will be discounted. In addition, a clean container should be prepared to hold the urine. The pregnancy test paper is divided into two parts, the part indicated by the arrows, which should be soaked in urine, and the display area, which is used to view the results. Place the pregnancy test in the urine in the direction of the arrow and wait for 5 to 6 minutes to see how the display area changes. If the display area is one bar, it means that you are not pregnant. If it is two bars, it depends on the depth of the color. If it is two dark red marks, you are pregnant. If it is one dark and one light, it is weakly positive in two ways. One is that the test is too early and the HCG level is not high enough. The other is a false positive. If a false positive is suspected, the test should be repeated in 2 to 3 days. If a woman checks for pregnancy, she should seek medical attention and have her blood HCG tested to improve accuracy.
