Shipping Requirements

To avoid hemolysis, serum should be removed from the clot and aliquoted to another tube prior to shipping. Hemolysis affects serologic testing and may cause a sample to be rejected. Samples should be kept cold during transport. Avoid freeze-thaw cycles.

Additional Instructions

APHIS-approved lab for Import/Export. Official Federal EIA Report form required with all submissions. Submitting veterinarians must accurately and fully complete the official form and uniquely identify the animal, including narrative descriptions. Please visit our Resources page for more information regarding completion of the EIA form.

An accession fee of $10 per case will be charged for EIA submissions received with a paper EIA Form 10-11.  The accession fee will be waived for electronic submissions (i.e., VSPS or Global Vetlink  – please send the printed lab submittal form with the samples). Original paper reports are no longer mailed to veterinarians or owners.  All Coggins test results and invoices will be emailed after testing has been completed.  An original paper copy of the results may be requested, however, the request must be indicated on/with the original submission form and an additional $5 handling/mailing fee will be applied.

Note: Samples for serologic testing must be received during business hours the day before scheduled testing to ensure inclusion in the test run. If not, the sample will be tested on the following scheduled test day. STAT testing may be available, contact the lab for more information.
