Pregnency tests

Caped Crusader

Any one know if pregnency tests can be wrong? My fiance is late and she has taken a test that says she is not pregnant. We still think that she may be so she has set up an apointment at the doctors later in the week to check it out. Are these tests usually pretty accurate or are they sometimes wrong?

Read the information that came with the test.

1000 people could tell you that they're always right but it could still turn out wrong.
Just be patient and go to the doctor.
Or else get another brand of test and give it a go, but I'm telling you, she can p!ss on sticks til the cows come home and you'll still end up going to the doctor at the end of the week!

Best of luck, whichever way.

(Come back and update us though.)

The tests are usually pretty accurate. There are however different possible reasons for both false negatives and false positives.

False negatives are particularly common up to three weeks after the act of intercourse that caused a pregnancy.

They're pretty accurate. I would assume it is correct until you hear otherwise from a doctor.

They are usually pretty accurate but like with anything they can be wrong sometimes. Going to the doctor will set your mind at ease. Hope you get the result you hope for.

I thought since the newer ones are looking for the presence of a particular hormone (hCG), they cannot give false positives? It's either there or it isn't. Sometimes it isn't there in high enough quantitites to register, and thus gives a 'false negative', but once it's there in quanitities enough to register, it's a positive.

With correct use (because a lot of them will have evaporation lines that look like a positive in any case if left way too long, but that isn't correct use) you can still get a false positive; there are a few reasons apart from pregnancy that can cause an elevated hCG. Since some of the reasons are medical conditions - and some of those quite serious - that would be a case where one should definitely see a doctor.

However, the OPs issue is with the chances of false negatives which as you say can happen (but is generally unlikely).

I pee'd on 13 yes 13 tests when I got a scare years back, it went 50/50 between positives and negatives, turned out positive when I took a trip to the Doctor, she advised that once you get one positive you can take it as a cert...'
