NEW in 2021: We are now accepting samples from outside the VMC, including primary care and referral clinic samples!
Flow cytometry is a highly specialized diagnostic technique, critical for diagnosis and immunophenotyping of hematopoietic malignancies such as leukemias and lymphomas. This can provide key prognostic information as well as inform therapeutic decisions. Flow cytometry can also be instrumental in the diagnosis of other neoplasms (ex: thymoma, plasma cell tumors, histiocytic neoplasms) or immunodeficiency disorders (ex: canine leukocyte adhesion disorder, FIV-related immunodeficiency, and others). The OSU VCFCS is the first veterinary diagnostic laboratory to utilize a spectral flow cytometer, the next generation of flow cytometry technology, which allows for high-parameter multiplexing in a single assay. This enables us to better distinguish complex cellular populations, even with deceased patient sample volume requirements.
We routinely analyze peripheral blood, lymph node aspirates, and other solid organ aspirates for canine and feline patients. The cost of flow cytometry for all canine or feline samples is $120, which can be paid using the OSU rDVM portal. For submission of peripheral blood samples, a concurrent CBC (within 48 hours) is required. If a recent CBC is not available, we can perform this testing at OSU on the same whole blood sample. The turn-around time for this assay is 1 to 3 business days; we understand that clinicians and clients rely on this information for initiating therapy.
The director of the new OSU VCFCS is Dr. Samantha Evans, a board-certified clinical pathologist who completed her residency training at Colorado State University and continues to work closely with the CSU Clinical Immunology Laboratory. That expertise, along with Dr. Evans’ PhD dissertation work on FIV using flow cytometry at the University of California Davis, have prepared her to lead this new service for OSU. If you have any questions about the VCFCS, please contact Dr. Evans, at email@example.com or 614-292-9706. We look forward to serving you and your patients!
