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.

The accession fee is waived for EIA submissions unless original paper copy is requested. As of February 1, 2018, original paper copies will no longer be mailed to veterinarians or owners. All Coggins test results and invoices will be emailed or faxed after testing has been completed. If you prefer an original paper copy and it is indicated on the submission form, we will continue to provide this option, but a $10 accession fee will apply.

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.
