Recommended Uses: | To determine the presence or absence of rabies virus in an animal that has bitten or otherwise exposed a person or domestic animal to saliva, nervous tissue or cerebrospinal fluid. |
Contraindications: | Test not suitable for an animal exposed, just the animal suspected of carrying rabies virus. Not suitable for small rodents (especially pets) without consultation with the county's designated public health official. Not suitable for diagnosis in humans. |
Additional Tests Performed: |
Patient Preparations: | Patient (in cases where a human has been exposed) should consult with physician. Bite wounds or other skin breaks or mucous membrane exposure should be treated as any comparable wound. In extremely high risk cases, rabies post-exposure prophylaxis may be started. Owners of exposed domestic animals should consult with a veterinarian. |
Specimen Requirements: | The entire brain including the cerebellum and brain stem, or the whole head or the entire animal if squirrel-sized or smaller. Tissue must be fresh (not chemically fixed) and not decomposed. |
Specimen Handling & Transport: | Package the specimen so that NO leakage will occur in transit. Specimens are preferred refrigerated but not frozen. Specimens must be packaged in compliance with applicable transportation safety regulations. |
Collection Kit/Container: |
