Early pregnancy test strip is a convenient reagent for women to test whether they are pregnant, but it can only be used as a preliminary screening test because sometimes false positive or false negative test results may occur. Generally, after about 40 days of amenorrhea, the levels of chorionic gonadotropin in the serum or urine of pregnant women can be measured to assist in diagnosing early pregnancy. So if the test strip is negative, is she pregnant?
1. If a woman's urine pregnancy test is negative after half a month of intercourse without confirming ovulation, and the quality of the test strips used is satisfactory and the testing procedure is accurate, the possibility of pregnancy can be basically ruled out because the probability of false negatives on the test strips is not high. You can determine if you are really pregnant by going to the hospital for a check-up.
2. If the patient's urine pregnancy test is conducted for a short period of time, or if there are issues with the quality of the test strips used or the testing procedure, and the urine pregnancy test is negative, the possibility of pregnancy cannot be ruled out. Patients can also go to the hospital for ultrasound examination, which can not only detect whether they are really pregnant, but also determine the length of pregnancy.
3. In addition, the use of early pregnancy test strips is to insert the test end of the early pregnancy test strip into the urine without exceeding the control line, ensuring that the strip is effective and not damp. After 4 to 5 seconds, take it out and place it flat. Then observe the results within 4 to 5 minutes. If the time is too long, the test results may not be accurate.
