The MSU VDL's thyroid testing will no longer include measurement of free T3. We will implement this change in late May/early June after our supply of reagent is depleted. The MSU VDL Endocrinology Laboratory will continue to assess T3, the active form of thyroid hormone, as total T3. This change will reduce the number of samples with insufficient volume for a complete thyroid profile and will contribute to our efforts to reduce radioactive waste generated by the laboratory. In anticipation of this adjustment to our thyroid profiles, the prices for those assays were minimally impacted by our fee increase in January.
