Reference Interval
Effective May 9, 2011
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.
