Research Summary
The Clinical Pathology Group provides technical, collaborative and consultative clinical pathology support for investigators at NIEHS and the Division of Translational Toxicology (DTT). The laboratory provides basic services in hematology, clinical chemistry, urinalysis and cytology with capabilities to analyze both animal and human specimens. Special assays also have been performed including the determination of hormone, growth factor, prostaglandin and chemokine/cytokine concentrations; bone marrow cytology; methemoglobin concentration; and cholinesterase and isoenzyme evaluations. Over time, considerable efforts regarding acquisition of equipment, upgrading standard operating procedures, implementing appropriate data management, quality control, quality assurance, and proficiency testing programs have been made to ensure that these laboratories continue to provide high quality clinical pathology services. For over two decades, the Clinical Pathology Group has been a valuable resource for the Institute.
Michelle Cora, D.V.M., D.A.C.V.P., leads the Clinical Pathology Group within the Comparative and Molecular Pathogenesis Branch (CMPB). She earned her Doctor of Veterinary Medicine (DVM) degree from University of Illinois; residency training in veterinary clinical pathology from North Carolina State University, College of Veterinary Medicine (NCSU-CVM) and training in toxicological clinical pathology as a DTT toxicological clinical pathology research fellow. She has been a Diplomate of the American College of Veterinary Pathologists since 2011.
