Blood Test Positive and Stool Test Negative -redo?

Blood tests (for antibody) are used to screen for H.pylori. They remain positive for many months after treatment so can only be used as the initial test. Urine antibody is a "pregnanacy style" urine test. Accuracy is slightly less than blood tests. A negative blood test is good evidence that Hp is NOT present. Use it to exclude the diagnosis (but no test is 100% perfect remember).

Thank you, Helico expert! I appreciate your taking the time to comment. I am definitely going to use the pepto bismul 4 times per day. My doctor agreed, as well, as it is over the counter. :)
