Reference Range:

Components	Reference Interval
Influenza A Virus Antibody, IgG	0.89 IV or less: Negative -? No significant level of influenza A virus IgG antibody detected. 0.90-?1.10 IV: Equivocal -? Questionable presence of influenza A virus IgG antibody detected. Repeat testing in 10-?14 days may be helpful. 1.11 IV or greater: Positive -? IgG antibodies to influenza A virus detected, which may suggest current or past infection.
Influenza A Virus Antibody, IgM	0.89 IV or less: Negative -? No significant level of influenza A virus IgM antibody detected. 0.90-?1.10 IV: Equivocal -? Questionable presence of influenza A virus IgM antibody detected. Repeat testing in 10-?14 days may be helpful. 1.11 IV or greater: Positive -? IgM antibodies to influenza A virus detected, which may suggest current or recent infection.
Influenza B Virus Antibody, IgG	0.89 IV or less: Negative -? No significant level of influenza B virus IgG antibody detected. 0.90-?1.10 IV: Equivocal -? Questionable presence of influenza B virus IgG antibody detected. Repeat testing in 10-?14 days may be helpful. 1.11 IV or greater: Positive -? IgG antibodies to influenza B virus detected, which may suggest current or past infection.
Influenza B Virus Antibody, IgM	0.89 IV or less: Negative -? No significant level of influenza B virus IgM antibody detected. 0.90-?1.10 IV: Equivocal -? Questionable presence of influenza B virus IgM antibody detected. Repeat testing in 10-?14 days may be helpful. 1.11 IV or greater: Positive -?
