Reference Range

Less than 1:64: Negative - No significant level of Rickettsia rickettsii IgG Antibody detected.
1:64 - 1:128: Low Positive - Presence of Rickettsia rickettsii IgG Antibody detected, suggestive of current or past infection.

Clinical Significance

This test is for antibodies to Rickettsia rickettsii. Any antibody reactivity to Rickettsia rickettsii should, however, also be considered group reactive for the Spotted Fever group (Rickettsia conorii, Rickettsia australis and Rickettsia sibirica).

This test is for antibodies to Rickettsia rickettsii. Any antibody reactivity to Rickettsia rickettsii should, however, also be considered group reactive for the Spotted Fever group (Rickettsia conorii, Rickettsia australis and Rickettsia sibirica). A low positive suggests past exposure or infection, while high positive results may indicate recent or current infection, but are inconclusive for diagnosis. Seroconversion between acute and convalescent sera is considered strong evidence of recent infection. The best evidence for infection is a significant change on two appropriately timed specimens where both tests are done in the same laboratory at the same time.Analyte Specific Reagents (ASRs) are used in many laboratory tests necessary for standard medical care and generally do not require FDA approval.
