WBC count is normal in most cases of Enteric fever. Leukocytosis makes diagnosis less likely. Leukopenia perceived to be an important feature of typhoid fever has been reported in only 20 - 25% cases. The differential count is usually unremarkable except for eosinopenia. Eosinopenia, often absolute, may be present in 70 - 80% cases. Presence of absolute eosinopenia offers a clue to diagnosis but does not differentiate enteric fever from other acute bacterial or viral infections. Conversely, a normal eosinophil count does make typhoid fever a less likely possibility.
