Are test strips accurate?

With the development of medical technology in my country, many female friends will use test strips as the only tool to detect pregnancy when they are testing for pregnancy. In addition to the fact that test strips are convenient, quick, and can be purchased anywhere, the accuracy of test strips is generally quite high, and the actual results are very close. However, if mistakes occur during the testing process, it may also lead to inaccurate results. So are early pregnancy tests accurate?

Experts tell us that the accuracy of early pregnancy test strips is actually about 50% to 75%, and you need to pay attention to the correct use of the early pregnancy test strips when operating them. Also, if you detect pregnancy, you need to go to a regular obstetrics and gynecology hospital for a detailed examination in time to determine the accuracy of the results. So are the test strips accurate?

Are test strips accurate?

The earliest pregnancy test can be used is about 33 days after menopause. If the test cannot determine whether you are pregnant, you can do another test about 37 days after menopause. Although early pregnancy test strips are said to have a 99% accuracy rate, in reality the correct testing rate of early pregnancy test strips varies greatly, ranging from 50% to 75%. Early pregnancy test strips are easily affected by external factors such as temperature and humidity, resulting in differences in test results.

Generally, if you want to improve the accuracy of early pregnancy test strips, you must master the correct use of early pregnancy test strips. In addition, pay attention to the following points when using early pregnancy test strips:

1. If the pregnancy test paper you purchased is stored for more than one year, or if it is exposed to moisture and is not stored at normal room temperature, it may become invalid and result in a false negative test result.

2. If the pregnancy has just begun, or there is a possibility of ectopic pregnancy, the HCG level in the body is generally low. The test sample needs to be left to stand for more than 3 minutes, and must be carefully identified for weak positive results - the color band in the test area only appears faintly.

3. In extreme cases, such as hydatidiform mole and choriocarcinoma, the HCG level in the body will be too high and the urine test will not show a positive result.

4. A positive result does not mean 100% pregnancy. There are a number of non-pregnancy factors that can cause a positive test result.

5. After 3 months of pregnancy, HCG levels decrease and urine tests may sometimes be negative or weakly positive.

As for whether early pregnancy test strips are accurate, the answer is no. In fact, it is generally better to use early pregnancy test strips 33 days after menopause. In addition, the results should be retested 37 days after menopause. In addition, if the purchased test strips are stored for too long, it is easy to cause errors in the results. Therefore, if you want to know whether you are pregnant, it is best to go to a regular hospital for a series of examinations.
