Bartonella, Molecular Detection, PCR, Varies
Use
Aiding in the diagnosis of Bartonella infection, which can cause conditions like cat scratch disease, bacillary angiomatosis, peliosis hepatitis, and endocarditis. The test uses PCR to detect Bartonella species by amplifying a specific sequence of the citrate synthase gene. This real-time PCR test provides rapid identification and is more sensitive than culture, which has limitations due to Bartonella's fastidious growth requirements.
Special Instructions
Not provided.
Limitations
This test does not differentiate between Bartonella henselae and Bartonella quintana. A negative result does not rule out the presence of the organism or active disease due to potential PCR inhibition, sequence variability, or low DNA quantities. Inhibition has been noted in formalin-fixed, paraffin-embedded tissues. Results should be correlated with clinical presentation.
