How accurate is an expired pregnancy test (2 years old)? I used it and got a positive test. Is this accurate?

I have not confirmed this with the makers of pregnancy tests, but usually tests become less sensitive over time, then stop working all together. This means there is a greater chance for a false negative test as opposed to a false positive test. Best to have it confirmed at your doctors office. ...Read more

I would start with determining what type of surgery you had and see a physician as soon as possible. ...Read more
