Rickettsia rickettsii IgG Antibody Test
Confirm past exposure to Rocky Mountain spotted fever.
The Rickettsia rickettsii IgG Antibody Test is a blood test used to detect antibodies against Rickettsia rickettsii, the bacterium that causes Rocky Mountain spotted fever (RMSF). This test is primarily used to determine whether a person has been previously infected with this tick-borne pathogen. It is helpful for individuals who have had a tick bite or have experienced symptoms consistent with RMSF, and for those who may have been exposed in endemic areas. IgG antibodies typically appear later in the course of infection and can persist for months to years, making this test useful for confirming past exposure rather than acute infection.

- Rickettsia rickettsii IgG Antibody: Detects the presence of IgG antibodies specifically directed against Rickettsia rickettsii, indicating past infection or exposure.
Why it matters
Rocky Mountain spotted fever can be a severe and potentially life-threatening illness if not treated promptly. Identifying past exposure through IgG antibodies helps in understanding a patient's history of tick-borne infections, which can inform clinical management and public health surveillance. This test is particularly valuable for individuals with a history of tick bites or those living in or traveling to endemic regions.
