Rickettsia rickettsii IgM Antibodies IFA  < 1:64  titer 

PRIMARY
1 Serum 1 (0.5) mL   Frozen - 2 Month(s)/Refrigerated - 5 Day(s)  
ALTERNATE

Helps establish the diagnosis of infection due to Rickettsia in the Rocky Mountain spotted fever group or in the typhus group. The presence of R, rickettsii specific IgM is diagnostic for current or recent infection; however, its absence does not rule out RMSF. Both R. rickettsii IgM and IgG are usually detectable within 1 week after onset of symptoms. R. rickettsii IgM concentrations peak after 3 weeks and decline rapidly but can remain detectable for about 1 year. Reactivity to R. typhi antigen should be considered "group-reactive" because the R. prowazekii infection also induces antibodies reactive with R. typhi.
