Bartonella henselae & B. quintana Antibodies, IgG & IgM
Also known as: BARTONELLA
Use
This test may confirm a current or past exposure to Bartonella henselae or Bartonella quintana in a patient with typical signs, symptoms, and a compatible exposure history. It can help differentiate between B. henselae and B. quintana infection through the presence of specific IgG and IgM antibodies, thereby guiding appropriate clinical management.
Special Instructions
Not provided.
Limitations
This test was developed by ARUP Laboratories and its performance characteristics determined; it has not been cleared or approved by the US Food and Drug Administration. IgM antibodies may occasionally persist for more than 12 months post-infection. High positive IgG indicates recent or current infection but is inconclusive for diagnosis without seroconversion evidence between acute and convalescent sera. The best evidence for infection is significant change on two appropriately timed specimens processed in the same laboratory.
