Component Interpretation
Rickettsia rickettsii (Rocky Mountain Spotted Fever) Antibody, IgG Less than 1:64  Negative - No significant level of IgG antibody detected.
1:64 - 1:128  Low Positive - Presence of IgG antibody detected, suggestive of current or past infection.
1:256 or greater  Positive - Presence of IgG antibody suggestive of recent or current infection.
Rickettsia rickettsii (Rocky Mountain Spotted Fever) Antibody, IgM Less than 1:64  Negative - No significant level of IgM antibody detected.
1:64 or greater  Positive - Presence of IgM antibody detected, which may indicate a current or recent infection; however, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection.
Rickettsia typhi (Typhus Fever) Antibody, IgG by IFA Less than 1:64  Negative - No significant level of IgG antibody detected.
1:64-1:128  Equivocal - Questionable presence of IgG antibody detected.  Repeat testing in 10-14 days may be helpful.
1:256 or greater  Positive - Presence of IgG antibody detected, suggestive of current or past infection.
Rickettsia typhi (Typhus Fever) Antibody, IgM by IFA Less than 1:64  Negative - No significant level of IgM antibody detected.
1:64 or greater  Positive - Presence of IgM antibody to detected, which may indicate a current or recent infection; however, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection
