Once negative after treatment

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).
