Overview

The Central Ligand Assay Satellite Services (CLASS) laboratory, housed within the University of Michigan’s Department of Epidemiology, offers comprehensive, end-to-end support for clinical research. We streamline the research pipeline by providing custom-designed collection kits with barcoded, uniquely identified components, followed by secure processing and 24/7-monitored ultra-low or liquid nitrogen storage. With capabilities spanning over 40 routine assays—including ELISA, open-channel chemistry, and coagulation analysis—CLASS is a proven leader in data generation. Over the past 20 years, we have successfully managed more than 1 million samples, produced 100,000 kits, and executed 1.25 million assays, ensuring the highest standards of safety and accuracy for your study.

Goals and Philosophy

The CLASS Laboratory uses state-of-the-science, reliable, precise, and cost-effective analytical methods that minimize variability, provide long-term sample and assay stability, and maximize assay reliability. We incorporate internal quality assurance procedures that minimize error and variability as assessed by rigorous quality control procedures.

We have developed, and employ, electronic data handling systems and analysis procedures that provide increased efficiencies, reduce labor costs, eliminate manual operations to reduce the possibility of errors, and preserve assay and analysis data.

We use sample labeling and handling systems that ensure positive identification of sample and result while maintaining the integrity of the sample. Samples are handled in ways that maximize preservation of all residual sample; and aliquots of unused samples destined for storage are handled in ways that maximize their value to future studies. We ensure that the confidentiality of samples submitted to the laboratory is maintained.
