Western blot tests appear to have greater specificity. The DNA of various Bartonella species can also be amplified by polymerase chain reaction (PCR) in blood, spinal fluid, and tissue; given the cross-reactivity of the Bartonellaantibody tests, PCR may be the most reliable and useful test for Bartonella infection.
Can Bartonella be chronic?
It is possible to be chronically infected with Bartonella and not have disease symptoms. The extent to which persistent infection in outwardly healthy individuals ultimately contributes to organ system pathology is unknown.
