Approved OFA Thyroid Laboratories

The laboratory certification process will include quality control, quality assurance and reagent certification. Laboratories may apply and, if successful, will be approved to perform analysis for OFA thyroid certification. A site visit by a qualified veterinary endocrinologist chosen by the OFA will be required and continued quality assurance and quality control will be necessary to maintain certification. Fully certified status can be obtained by passing the site visit and passing the results of the first OFA quality assurance assay result test. The approved laboratory must be contacted for the appropriate submission forms, sample handling procedures, and laboratory service fee before collecting the sample.
