A member asked:

Can you still have h pylori after having a negative blood test for it ?

Dr. Gerald Mandell answered

Specializes in Nuclear Medicine

Early in infection: When a blood antibody test is done early in an h. Pylori infection, the results may be falsely negative because the level of antibodies is too low to measure.
