Did you know that if you use an expired or damaged pregnancy test, you can get a inaccurate test reading? I just did a little research before I purchased some expired tests. I found that the reason for this is because of the hormones and molecules that are used in creating the test break down over a period of time. Therefore it's best to buy one not-expired or as close to the expiration date as possible.

*Side Note* It's also common to get a "false-positive" reading if you have traces of blood or protein in your urine. Various prescription drugs — including diuretics and promethazine (used to treat allergy symptoms and nausea) — also can cause a false-positive result.

Just thought someone else might consider this helpful before buying expired tests on Ebay.
