how accurate are pregnancy tests?

Question

my housemate just got a positive result, two days after her period was due. what sort of things might give her a false positive result? what are the chances that she is pregnant?

Answer 1

I ve heard that they are only 98% true...

Answer 2

It all depends on the test, but usually they give false negatives, not false positives. They test changes to the red, or positive sign, when it finds a certain hormone in the urine, so is usually unlikely to give false information. Hope this helps!

Answer 3

False Positives are Very Rare.
Unless she is on some type of Hcg hormone shot then I would say she is Definitely Pregnant.

Answer 4

I would tell her to take one more just to be sure, but you cant have a false positive unless she is on fertility drugs with the HcG hormone. Best of luck to her and be there and help her through this.

Answer 5

depends on the brand - most are 99% accurate

check with your GP if you want it confirmed

false positives can be caused by certain meds / incorrectly doing the test / leaving the test too long b4 reading the result

Answer 6

possitives are very accurate its the negative results that can be wrong. Do two to double check then book in to see the doctor

good luck x

Answer 7

Pegnancy tests are in my personal opinion 98% accurate well it depends on which one you use theres a high posibility she could be but also stress can cause an inbalance also to your body. so the best thing to do would be to go to a doctor to be 100% accurate

Answer 8

the ones that i used were 99.9% accurate. If your friend is worried, tell her to visit a doc and they can tell her for sure if she is preg. or not.

Answer 9
