    The standard serologic test for diagnosis of RMSF is the indirect immunofluorescence antibody (IFA) assay for immunoglobulin G (IgG) using R. rickettsiiantigen.
    IgG IFA assays should be performed on paired acute and convalescent serum samples collected 2–4 weeks apart to demonstrate evidence of a fourfold seroconversion.
    Antibody titers are frequently negative in the first week of illness. RMSF cannot be confirmed using single acute antibody results.
    Immunoglobulin M (IgM) IFA assays are available through some reference laboratories, however results might be less specific than IgG IFA assays for diagnosing a recent infection.

    Antibodies to R. rickettsiimight remain elevated for many months after the disease has resolved.
    In certain people, high titers of antibodies against R. rickettsiihave been observed up to four years after the acute illness.
    Ten percent or more of healthy people in some areas might have elevated antibody titers due to past exposure to R. rickettsiior other SFGR.
    Comparison of paired, and appropriately timed, serologic assays provides the best evidence of recent infection.

    Polymerase chain reaction (PCR) amplification is performed on DNA extracted from whole blood.
    R. rickettsii infect the endothelial cells that line blood vessels and may not circulate in large numbers in the blood until the disease has progressed to a severe phase of infection.
    Although a positive PCR result is helpful, a negative result does not rule out the diagnosis, and treatment should not be withheld due to a negative result.
    PCR might also be used to amplify DNA from a skin biopsy of a rash lesion, or in post-mortem tissue specimens. See instructions for the collection of a skin biopsy pdf icon[PDF – 1 page].

    Culture and immunohistochemistry (IHC) assays can also be performed on skin biopsies of a rash lesion, or post-mortem tissue specimens.
    Culture isolation and IHC assays of R. rickettsiiare only available at specialized laboratories; routine hospital blood cultures cannot detect the organism.

    Apr 5, 2023 · Rocky Mountain spotted fever (RMSF) is a systemic vasculitis caused by infection with Rickettsia rickettsii, a tick-borne, gram-negative, intracellular bacterium. [1] . Rickettsia rickettsii is one of the spotted fever group rickettsiae and is closely related to the other group members by genetic and antigenic characteristics.
