I am wondering how soon the breath test turns positive after possible infection. I am anxious to have the test, but i dont want to do it too soon, as i dont want a false negative. I understand it takes 3 weeks for blood tests to turn positive for antibodies , but I am pretty sure it would be less for the breath test to turn positive. Does anyone know the answer to this? i cant not find any info on the internet regarding this question. thanks

it only takes 10 minutes for UBT to show result. However, depending on the laboratory testing time, it'll probably take a week or 2 before you receive the test result.

there is no such thing as "doing it too soon", unless you had taken antibiotics or any acid reducing agents.

in order for UBT to work, you'll need to have a acidic stomach. to further reduce the false negative result, you have to stop antibiotic for at least 2 weeks.

thank you, i was actually wondering how long from the time of possible infection-to the time of breath testing is it necessary to wait. is 2 weeks long enough,from the date of possible infection (if you havent taken any meds) to have a sufficient bacterial load to have a positive reponse to the test > i guess that was what i am asking? thanks

oh.. tricky... but I would assume 2 weeks is more than enough for the infection to be detectable. However, it not easy to be infected in adult-hood.
