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

10-15 U/mL

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.
Methodology:
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
