Interpretive

Reference Range:
Francisella tularnensis, Antibody, IgG with Reflex to Agglutination:  
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 with Reflex to Agglutination:
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 past exposure/immunization.

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

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.
