The price of the pregnancy test stick has no uniform standard, because different manufacturers, different types of products and different ways in the use of the process, as well as the difference between hardcover and simple packaging, the price varies, generally ranging from a few dollars to several dozen dollars. The pregnancy test stick does not have much to do with the price in the usual testing process, and its main function is the same. Generally, you can detect whether you are pregnant through pregnancy test paper 14 days after having intercourse during ovulation, and generally observe the test result within 5 minutes. If two red lines of equal color appear on both the control line and the test line, it is positive, indicating a higher possibility of pregnancy; if there is only a red line on the control line and no reaction on the test line, it is negative and the possibility of pregnancy is small; if there is a positive test line and no reaction on the control line, it is a sign of test failure. If the test paper shows a positive result, it is recommended to go to the hospital to confirm whether you are pregnant and to exclude the possibility of ectopic pregnancy and other diseases. In addition, it is recommended to choose a pregnancy test from a regular manufacturer within the production period and to avoid moisture in the pregnancy test because moisture will cause the chemical reagents to fail and affect the accuracy of the test results.
