How long should I wait for H pylori breath test C13

[MatildaUK]

Hello there,
I have been referred for a C13 breath test. Because the doctor originally thought that my abdo pain may have been caused by an infected gallbladder, he prescribed Co-amoxiclav 250/125mg tablets. Had upper abdo scan 2 days later that ruled out any g-bladder problem. However, I had taken 3 antibiotics tabs by then. Doctor said I would then need to wait for C-13 test. He said wait 2 weeks. At the moment it is 18 days since the last antibiotic and I am booked in for a test on the 22nd day after. Do you suggest that I wait 6 more days until the 28th day, or should 22days be acceptable as I had only taken 3 antibiotic tablets?

the recommended waiting period is 3 weeks without antibiotic and acid reducing drug. however, i think 18 days should be enough for the breath test.
