Serology for H pylori not so sensitive.I was H. Pylori positive, diagnosed with biopsy when doing scopes. Then antibiotic and cleared.
So when my girl had company's med check, I asked her to add on H.P. in her blood test (remember at $35). Her result turned out -ve.
My son going for his med check soon and I also asked him to do the add-on.
*though my girl is -ve, I am still not sure about the blood test accuracy coz 'logically', I would have infected her with all these years of living together (but we do practise very good food/meal hygiene at home).

You may get your wife to add on H.P. test in her med check.
Urea Breath Test better.
Breath Test (Carbon Isotope-urea Breath Test, or UBT)
- Up to 2 weeks before the test, you need to stop taking antibiotics, bismuth medicines such as Pepto-Bismol, and proton pump inhibitors (PPIs).
- During the test, you swallow a special substance that has urea. Urea is a waste product the body produces as it breaks down protein. The urea used in the test has been made harmlessly radioactive.
- If H pylori are present, the bacteria convert the urea into carbon dioxide, which is detected and recorded in your exhaled breath after 10 minutes.
- This test can identify almost all people who have H pylori. It can also be used to check that the infection has been fully treated.
- Blood tests are used to measure antibodies to H pylori. Antibodies are proteins made by the body's immune system when it detects harmful substances such as bacteria.
- Blood tests for H pylori can only tell if your body has H pylori antibodies. It cannot tell if you have a current infection or how long you have had it. This is because the test can be positive for years, even if the infection is cured. As a result, blood tests cannot be used to see if the infection has been cured after treatment.
