This test is intended to be used as an aid in the diagnosis of infections caused by Bartonella henselae or Bartonella quintana.

Cross-reactivity with other potentially pathogenic Bartonella spp (eg, B vinsonii) may occur. Alternate approaches, such as serological testing, may be necessary to confirm infection caused by Bartonella spp, other than Bartonella henselae and Bartonella quintana.
