Normally, pregnancy tests can be used for between 20 and 26 months, provided that their original packaging is sealed.
It is true. According to the health advice of the Winnie Palmer Hospital for Women and Babies, pregnancy tests do expire. It is also important to understand that if they are used after the expiration date that is on the package, their results may not be accurate as the chemical in pregnancy tests is sensitive and can become less effective over time.
Pregnancy tests help detect whether the urine contains a hormone called human chorionic gonadotropin (HCG). This hormone is produced just after a fertilized egg attaches to the uterine wall and is a positive indicator of pregnancy.
Highlight// When you purchase a pregnancy test, check the label to verify that it has not expired.
Keep in mind that the accuracy of a pregnancy test may be questionable if the woman has ovarian cysts or if she is having an ectopic pregnancy. In both situations, it is common for women to experience bleeding. In any case, if the test is positive, it is best to see a physician to get a checkup.
