If you’ve ever taken a pregnancy test, you know that it’s nerve-wracking.
So, when you see two lines, it can be tempting to take the same test over and over again just to make sure the result is accurate.
But before you do that, here’s why re-using a pregnancy test isn’t recommended.
How Pregnancy Tests Work
Pregnancy tests detect the presence of human chorionic gonadotropin (hCG) in your urine. HCG is released by the placenta shortly after implantation occurs—which is usually 6-12 days after ovulation and conception.
If hCG is detected in your urine sample, then it will trigger an immunoassay reaction on the pregnancy test strip, causing it to show a positive result.
Why You Shouldn’t Re-use a Test
Pregnancy tests are designed to be used once and then discarded.
The reason for this is that the sensitive antibodies on the testing strip can break down if they are exposed to too much liquid or humidity—which can happen if you try to use them more than once.
This means that if you use a test more than once, it may give an inaccurate reading or no reading at all!
So, if you want an accurate result from your pregnancy test, only use each one once and discard them immediately afterward.
Taking a pregnancy test can be nerve-wracking enough as it is without having to worry about whether or not the results are accurate.
That’s why it’s so important not to re-use them!
Remember—if you want an accurate result from your pregnancy test then make sure that each one is only used once! Good luck!
