How many days pregnant can be tested with test paper

Pregnancy test can be used to detect 10-14 days.

After conception, fertilized eggs need a period of time to implant in the endometrium, which usually takes 6-7 days, after implantation begins to secrete human chorionic gonadotropin. As pregnancy progresses, human chorionic gonadotropin levels will gradually increase. Early pregnancy test is to determine whether pregnancy by detecting human chorionic gonadotropin in urine. However, in the early stages of pregnancy, hCG levels may be low and may not be accurately detected. about 10-14 days of pregnancy, hCG levels in urine may reach levels that can be detected by dipsticks.

Although dipstick testing is more convenient, there is a certain false positive or false negative rate. To improve accuracy, it is recommended to use morning urine for testing and strictly follow the instructions. If there are doubts about the test results, multiple tests or further tests such as blood tests can be performed at the hospital for a more reliable diagnosis.
