Issues with pregnancy tests
| Thu, 03-10-2005 - 10:55pm |
Haven't been here in a while!
Has anyone ever had an issue with false positives for home pregnancy tests because of the thyroid medications we take? I have taken 3 tests (2 positive, one negative) and am wondering if I am really pregnant or if there is an issue with this because of my meds (I am on synthroid and armour thryoid).

I really dont know.
Here's a site that has some reasons for false postives:http://www.babyhopes.com/articles/falsepositive.html
Thyroid medication wasn't one of the reasons.
Here's some other info from babycenter.com:
Is it possible to get a false positive result?
False positives — when the test says you're pregnant but you're not — do happen. The New Mexico study found two brands that gave occasional false positive results. If you get an early positive result and then get your period soon after, you may also have had what's called a "chemical pregnancy." That means a fertilized egg implanted in your uterus and developed just enough to start producing hCG but then stopped developing for some reason. This happens with about 30 to 50 percent of all fertilized eggs because they're abnormal or otherwise incapable of developing into and surviving as an embryo. If this is the case, you'll go on to get your period (though it may be a little heavier and a few days later than usual). When pregnancy tests were less sensitive than they are today, these so-called "chemical pregnancies" were never identified. Many practitioners think that's another good reason to wait until a week after your period is due to perform a home pregnancy test.
Note: An ectopic pregnancy can give you either a positive or negative result on a pregnancy test. Call your practitioner right away if you have any abdominal pain or abnormal bleeding, no matter what a pregnancy test tells you.
I hope this helps and that all is ok with you! Cathy :)
