| Components: | Rickettsia typhi IgG/IgM / Rickettsia rickettsii IgG/IgM | ||||||||
| Performed: | Tuesday, Thursday | ||||||||

| Specimen Collection Details | |||||||||
| Collection: | One 7.5 mL serum separator tube (SST). | ||||||||
| Handling: | Allow to clot, centrifuge and separate serum from cells and pour into a plastic vial. | ||||||||
| Stability: | 1 hour ambient, 5 days refrigerated, or 2 months frozen. | ||||||||
| Standard Volume: | 1 mL serum. | ||||||||
| Minimum Volume: | 0.5 mL serum. | ||||||||
| Transport: | Refrigerated. | ||||||||
| Comments: | Paired testing of acute and convalescent specimens is recommended. Helps establish the diagnosis of infection due to Rickettsia in the Rocky Mountain spotted fever group or in the typhus group. Reactivity to R. typhi antigen should be considered ‘group-reactive’ because the R. prowazekii infection also induces antibodies reactive with R. typhi. |
