How Long Does Recovery From H.pylori Infection Take?

4 weeks is what is recommended
Detailed Answer:
Hello and thanks for the question,
It somewhat depends upon the type of test being done but generally it is recommended that you wait 4 weeks before retesting is done.
A positive urea breath test, culture or rapid urea test any time after treatment is evidence of failure.
The reason for the recommendation to delay testing for 4 weeks is that it is felt that it may take that long for an incomplete treatment to allow bacteria to build up to a sufficient quantity that the test is negative. So you could have a negative test right after treatment, but still be positive it tested again in 4 weeks with an ineffective treatment.
The only exception to the 4 weeks if you are being tested with a stool antigen test, then you should probably wait 6-8 weeks before retesting.
Regards,
Dr. Robinson
