November 20, 2024 - The MSU VDL is temporarily unable to perform our 25-hydroxyvitamin D assay (20001) which will cause a short-term delay in 25-hydroxyvitamin D testing. Samples will be stored appropriately until testing can be completed.

For samples submitted for ionized calcium and PTH in addition to 25-hydroxyvitamin D, ionized calcium and PTH assays will be performed and results provided. The remaining sample will be held, and 25-hydroxyvitamin D results will be provided as testing is completed. Thank you for your patience and understanding.
