When submitting samples for diagnostic evaluation, the importance of a clearly written, detailed history cannot be overemphasized. Please provide relevant patient signalment, clinical history, physical exam findings, and laboratory results. When submitting a biopsy, please provide a detailed description of the lesion including the site from which the biopsy was taken.
- Submitting samples in syringes, with or without needles, is NEVER appropriate.
- Specimens submitted to the MU VMDL, including carcasses, tissues and agents isolated from samples, become the property of the MU VMDL.
- Specimens for rabies testing should be sent to the State Public Health Laboratory in Jefferson City, MO. Contact your local health department regarding proper submission of specimens or go to http://health.mo.gov/lab/rabies.php for additional information. Samples submitted to the VMDL for rabies testing will incur a fee for sample collection plus an additional fee for disposal of remains, if needed.
The Tests and Fees section provides a quick guide for the type of sample needed and special submission requirements, if any, for a specific test.
Please call the VMDL (1-800-862-8635) for guidance on tests or types of samples that are not listed in the Tests and Fees section. Testing human specimens for diagnostic purposes is outside the VMDL scope of work and is strictly prohibited.
- Samples must be labeled correctly to ensure accurate results.
- Use a pen or marker that will not smear if label gets wet.
- Label the primary container (blood tube, culturette, specimen jar, etc.) with the following information:
- Animal name or ID number
- Owner’s last name
- Veterinarian’s name
- Date sample collected if sending paired samples
- Time and date the sample was put in formalin if submitting for histopathology
- A printable template for labels, using Avery 8160, is available. These labels can be used for both the primary receptacle and secondary packaging.
- Check that the information on the specimen label matches the information on the submission form.
- Label the sample and submission form “Human Risk” if the sample may contain infectious agents hazardous to humans such as rabies virus, Francisella tularensis, Bacillus anthracis, Brucella, Leptospira, systemic mycoses, etc.
Appropriate packaging of samples submitted to the VMDL is extremely important. Leakage of samples or breakage of containers poses a hazard to all individuals handling the packages. Following the steps outlined below will facilitate safe delivery of samples to the lab.
1. Proper packaging requires the use of 3 components: a primary receptacle, secondary packaging, and tertiary packaging.
2. The primary receptacle is the blood tube, culturette, formalin-containing jar, etc. that the sample is placed in.
- Close the container completely.
- Label it. See Sample Labeling.
3. Place the primary receptacle in the secondary packaging.
- The secondary packaging may be a Ziploc bag, box, or other sealable container. For liquids, the secondary packaging must be leakproof; for solids, the secondary packaging must be siftproof.
- Primary receptacles must be packed in secondary packaging in such a way that, under normal conditions of transport, they cannot break, be punctured, or leak their contents into the secondary packaging.
- Place sufficient absorbent material between the primary receptacle and the secondary packaging to absorb all liquids in the primary receptacle(s) if breakage should occur.
- Seal the secondary packaging.
- Label the secondary packaging. If there is more than 1 secondary package, it is helpful to VMDL personnel if you label these “1 of 2” or whatever is appropriate.
- Formalin-containing samples require special care.
- If using the VMDL prefilled formalin containers, the primary receptacle, secondary packaging, absorbent material, and shipping box are all included. The prefilled formalin container is the primary receptacle. Seal the lid of this container with tape. The sealable, leak-proof bag serves as the secondary packaging. Please place all of the provided absorbent material inside of this leak-proof bag, wrapping it around the formalin container.
4. Place the secondary packaging(s) in the tertiary packaging (shipping container). This is usually a sturdy box which may contain a Styrofoam insert if shipping items with cold packs.
5. With the exception of fixed tissue, slides, and Tritrichomonas pouches, most samples require shipment with cold packs.
- Include sufficient cooling material for the volume of sample being sent, the length of shipping time, and the time of year.
- Put the cold packs in Ziploc bags to prevent condensation in the package.
- Please do not attach samples to the cold packs.
6. Add sufficient packing material (newspaper, packing peanuts, etc.) to fill the tertiary packaging.
7. Put the submission form in a Ziploc bag and place this inside the tertiary packaging.
8. Securely close the tertiary packaging.
These are general packaging guidelines. Refer to the links below for carrier-specific shipping requirements.
