Is the pregnancy test expired?

Pregnancy test paper expired is usually inaccurate.

After the pregnancy test paper expired, the chemical substances on the test paper may deteriorate, and the sensitivity and accuracy of the reaction will be seriously affected, resulting in deviation of the test results, which may lead to false positives or false negatives. In addition, expired pregnancy test paper may not effectively react with relevant components in urine, and may not accurately show whether pregnancy is true.

If expired pregnancy test paper is used, it is recommended to purchase a new, unexpired test paper for testing to ensure the accuracy of the results. At the same time, it is also necessary to strictly follow the instructions for use of the test paper to improve the accuracy of the test.
