Pregnancy tests are relatively accurate. Under the premise of correct use, the accuracy rate of the pregnancy test stick is generally above 90%, which is also related to the quality and operation time of the pregnancy test stick. If you want to achieve a higher accuracy rate, it is recommended to buy a pregnancy test stick from a regular drugstore and use it when your period is delayed for about one to two weeks, using the middle part of the morning urine and using it according to the instructions, the test results will be more accurate. If the pregnancy test stick is outdated or damp, operated at the wrong time or not according to the instructions, all these will cause inaccurate results of the pregnancy test stick. If you drink a lot of water before the test in order to increase the amount of urine, this will also cause inaccurate test results. Generally speaking, the results of pregnancy tests are still relatively accurate, if you are not sure, you can also go to a regular hospital to take blood to test pregnancy.
