About CLASS

The Central Ligand Assay Satellite Services (CLASS) laboratory is a unit of The University of Michigan, School of Public Health, The Department of Epidemiology. Founded in 1985 as part of the Reproductive Sciences Program as its central facility for analysis of reproductive hormones, our 1,700 square feet of off-campus University Laboratory space is devoted to handling samples and assays. We also have an additional 1,000 square feet of space fitted with heavy duty power outlets, additional air-conditioning, natural gas-powered back-up generator, and alarm systems for 45 large, ultra-low temperature (-80°C) chest freezers and 1 Liquid Nitrogen freezer for extended sample storage. Our facility also houses our Administrative and Information Technology offices and database and server clusters.

The CLASS Laboratory routinely performs more than 40 different assay types (primarily serum and urine reproductive hormones, cytokines and growth factors) and over the past 10 years has performed more than 850,000 individual assays, tracked more than 600,000 samples, and produced more than 50,000 collection kits.
