Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.




<1:1 Antibody Not Detected

> or = 1:1 Antibody Detected


Infection with Bartonella henselae has been associated with cat

scratch disease, bacillary angiomatosis, peliosis hepatis and

febrile bacteremia syndrome. Infection with Bartonella quintana

has been associated with trench fever and bacillary angiomatosis

in both HIV positive and negative individuals.


IgG crossreactivity between B. henselae and B. Quintana may

occur at any titer; however, the infecting species will typically

have the higher IgG titer. Crossreactivity of IgM between

the two species is limited and typically is not seen.


Diagnosis of infections of the central nervous system can be

accomplished by demonstrating the presence of intrathecally-

produced specific antibody. However, interpreting results is

complicated by low antibody levels found in CSF, passive

transfer of antibody from blood, and contamination via bloody
