Specimen Required
Patient Preparation
  
Collect
Serum separator tube.  
Specimen Preparation
Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.15 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as acute or convalescent.  
Storage/Transport Temperature
Refrigerated.  
Unacceptable Conditions
Contaminated, hemolyzed, or severely lipemic specimens.  
Remarks
  
Stability
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)  
Reference Interval
<1:64  Negative - No significant level of Bartonella henselae IgG antibody detected.
1:64-1:128  Equivocal - Questionable presence of Bartonella henselae IgG antibody detected.  Repeat testing in 10-14 days may be helpful.
≥1:256  Positive - Presence of IgG antibody to Bartonella henselae detected, suggestive of current or past infection.  
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.
