The MSU VDL is committed to providing accurate and reliable results and has a robust quality system in place to identify potential problems with assays. Through routine quality control checks, we’ve identified an issue with the reagents used to measure free T4 by equilibrium dialysis. We are working with the manufacturer to find a solution. Until we can demonstrate that it meets quality control requirements, we are unable to release results for free T4 by equilibrium dialysis. This affects the following assays:

• Free T4 by Dialysis (20021)
• OFA Canine Thyroid Profile (20014)
• Premium Canine Thyroid Profile (20011)
• Premium Non-Canine Thyroid Profile (20016)
• Premium Therapeutic Monitoring (20013)

In the interim, we will release partial reports for profiles. Updated reports, that include the free T4 by equilibrium by dialysis, will be released after we ensure the assay passes quality control. Interpretations will be released upon completion of the entire profile. Samples will be stored appropriately and processed in the order they were received.
