Core Assay Facility (CAF)

The Department of Psychology at the University of Michigan, Ann Arbor, houses a Core Assay Facility (CAF) dedicated to the assessment of hormones in humans and animals in research studies. A particular focus of the CAF is on the measurement of steroid hormones (e.g., cortisol, testosterone, progesterone, and estradiol) in saliva samples with radioimmunoassay methods. Other hormones can also be assessed (e.g., prolactin), other substrates can be accommodated (e.g. serum, urine or feces), and other methods can be employed (e.g. enzymimmunoassays).

Who can use the CAF?

The CAF’s assay services are available to researchers from within the University of Michigan. The CAF employs a lab technician who supervises all activity in the lab and can perform hormone assays. Researchers may send samples directly to the lab to be assayed by our laboratory technician on a recharge basis. In addition to assay services, the CAF also serves as a training facility for faculty and students who are interested in including measures of hormones and immune system functioning in their research. We anticipate offering one training session each semester with CAF Director Jacinta Beehner and the laboratory technician. Customers with sufficient training in hormone assessment and general laboratory techniques can also run their own assays in the CAF for a lower recharge rate. The CAF is not licensed for clinical assessment of endocrine status. As such, results generated by the CAF neither substitute proper clinical assessment of endocrine status nor should they be interpreted clinically.
