Why normal White Blood Cell Count & H. pylori



I was tested for the stomach bacteria H. pyloir and the test was abnormal, at 2.93. The doctor gave me Prevpac.

My question is: How did I have an active H. pylori infection when my levels of white blood cells (WBC) were normal?

Does infection always make the white blood cell count go up? Can the WBC count be normal when there is an active infection in the body?


H. pylori is not an infection which causes your WBC count to rise. Infections in which you feel "sick with fevers" are usually the ones that rise the wbc. H. pylori stays in stomach/small bowel and does not enter blood stream per se.
