Reference Range:

Francisella tularensis Antibody, IgG
9 U/mL or less
  Negative - No significant level of IgG antibody to Francisella
  tularensis detected.

10-15 U/mL 
  Equivocal Questionable presence of IgG antibody to Francisella
  tularensis. Repeat testing in 10-14 days may be helpful.

16 U/mL or greater
  Positive - Presence of IgG antibody to Francisella tularensis
  detected, suggestive of current or past exposure/immunization. 


Francisella tularensis Antibody, IgM
9 U/mL or less
  Negative - No significant level of IgM antibody to Francisella
  tularensis detected. 

10-15 U/mL
  Equivocal - Questionable presence of IgM antibody to Francisella
  tularensis. Repeat testing in 10-14 days may be helpful. 

16 U/mL or greater
  Positive - Presence of IgM antibody to Francisella tularensis
  detected, suggestive of current or recent exposure/immunization.

Interpretive Data:

Cross reactivity with Brucella and Yersinia antibodies may occur. Therefore, results should be interpreted with caution and correlated with clinical information. The best evidence for current infection is a significant change on two appropriately timed specimens, where both tests are performed in the same laboratory at the same time.

Comments:

NOTE: If the ELISA testing is equivocal or positive for IgG and/or IgM, then Francisella tularensis Antibodies by Agglutination will be added. Additional charges apply.

Methodology:

Semi-Quantitative Enzyme-Linked Immunosorbent Assay
