Much of the work carried out by DTT is in support of the National Toxicology Program (NTP), an interagency partnership of the Food and Drug Administration, National Institute for Occupational Safety and Health, and NIEHS.
Hematology & Clinical Chemistry
The Clinical Pathology Group provides collaborative and consultative clinical pathology support for investigators at NIEHS. The laboratory provides basic services in hematology, clinical chemistry, and urinalysis. Special assays also have been performed including the determination of hormone, growth factor, prostaglandin and chemokine/cytokine concentrations, bone marrow cellularity and differential counts, methemoglobin concentration, b-hydroxybutyrate concentration, cholinesterase and isoenzyme evaluations.
The Clinical Pathology Group consists of the hematology and clinical chemistry laboratories and is currently staffed by two full-time NIEHS medical technologists and one on-site contract employee. Over time, considerable efforts regarding acquisition of equipment, upgrading standard operating procedures, developing historical data bases for control animals and 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 hematology and clinical chemistry analyses. For almost two decades, the Clinical Pathology Group has been a valuable resource for the institute.
