Interpretive Data

A low positive result suggests past exposure or infection, while a high positive result may indicate recent or current infection, but is inconclusive for diagnosis. Seroconversion between acute and convalescent sera is considered strong evidence of recent infection. The best evidence for infection is significant change on two appropriately timed specimens where both tests are done in the same laboratory at the same time.


Component Interpretation
Bartonella henselae Antibody, IgG with Reflex to Endpoint Titer Negative - No significant level of Bartonella henselae IgG antibody detected.
Equivocal - Questionable presence of Bartonella henselae IgG antibody detected.  Repeat testing in 10-14 days may be helpful.
Positive - Presence of IgG antibody to Bartonella henselae detected, suggestive of current or past infection.
