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.
Methodology:
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
