Brief Description

Rabies Fluorescent Antibody

Rabies testing is available at the State Public Health Laboratory on a daily basis. The laboratory does more than 2000 specimens annually from across the state of Missouri. Animals suspected of having rabies infection may be submitted for testing through a veterinarian, local or county health department office, district health representative, or other health care provider.

Specimen Collection

Avoid damage to the brain.  Do not shoot or crush the skull.

Have a qualified individual remove the animal head from the body.  Do not ship whole animals except for bats and small rodents.

Package the animal head so that it does not leak. Allow excess blood to drain before placing the head in the shipping container.

Use ONLY freeze packs as refrigerant in the shipping container. Never put ice in a rabies mailing container.

Fill out the laboratory form and return it to the enclosed envelope. Please include your phone number and mailing address.

Do not use staples on the laboratory form or envelope.

If submitting only tissue samples, please ensure that an adequate specimen is collected. The laboratory must receive a full cross-section of the brain stem and either the cerebellum or hippocampus. Contact the laboratory before collecting tissue samples. Rabies samples should be kept refrigerated until submitted for testing. Freezing is not recommended, but will NOT affect the test results. Repeated freeze-thaw cycles should be avoided.

Storage/Transport

Refrigerated

Rabies specimens should be submitted for testing through a veterinarian, local or county health department office, district health representative, or other health care provider. Shipping containers and instructions are supplied by the laboratory. Do not ship animal heads without obtaining proper shipping containers and instructions.

Shipping containers are provided by the laboratory for the transport of animal specimens. A free courier service is provided for the transportation of specimens to the laboratory. Do not ship animal heads without obtaining proper shipping containers and instructions. Do not ship rabies boxes by UPS or the U.S. Postal Service. Specimens may be delivered directly to the laboratory if courier delivery is unavailable.

The State Public Health Laboratory is supplying a certified rabies mailer that meets the Infectious Disease regulations required by the Department of Transportation. It is very important that this mailer be used in its entirety, including the enclosed documentation and labeling. Please to not alter or discard any component of the mailer. This mailer is provided for the protection of your staff, the courier service, and laboratory employees. The submitting facility is responsible for any fines that could be incurred because of failure to follow shipping guidelines as detailed in the mailer.

Packaging Instructions

The Missouri State Public Health Laboratory (MSPHL) performs rabies-specific laboratory testing on animal specimens submitted for rabies examination. Animal specimens are not tested for any other disease or pathogen by the MSPHL.

Because the MSPHL cannot ensure that remaining animal tissue does not pose a risk of disease transmission, any unneeded material is incinerated or destroyed after rabies testing is completed. Animal material may be transferred for additional testing or examination only to another laboratory or veterinary facility. Under no circumstances will any animal remains be transferred to any individual other than a laboratory or veterinary medical facility.
