Clinical Pathology is the branch of pathology directed to the diagnosis and monitoring of diseases via examination of blood, bodily fluids, secretions, and biopsy specimens. The Clinical Pathology section evaluates these specimens for chemical, morphologic, and immunologic abnormalities. A variety of test procedures and microscopic examinations are performed to confirm a clinical impression, establish or exclude a diagnosis, monitor therapy, and help establish a prognosis.
The Clinical Pathology Laboratory of the MSU VDL offers a full range of veterinary diagnostic testing in the areas of clinical biochemistry, hematology, hemostasis, urinalysis, and cytology. The laboratory is staffed by four ACVP board-certified veterinary clinical pathologists. Our highly qualified technical staff consists of certified Medical Technologists and Medical Laboratory Technicians with extensive experience in veterinary testing and knowledge of species differences. Careful attention to quality assurance ensures the accuracy of results. Laboratory-specific reference intervals are available for dogs, cats, cows, and horses.

Turnaround Time for Results
The majority of testing is performed with results reported on the same day samples are received. Due to the labor, time and cost involved, a few low-volume, specialty tests are completed once a week. These include:
- ANAs (performed on Tuesdays with results available Wednesday)
- Protein electrophoresis (performed on Wednesdays with results available on Thursday)
If data are critical to your patient, you may request that a test be performed stat for an additional fee. All submissions are considered important and samples are analyzed as rapidly as possible in the order in which they are received in the laboratory. A designation of stat means that testing on that sample will be performed prior to testing of all pending routine samples.
Cytology samples that arrive at the Clinical Pathology Laboratory before mid-afternoon will be reported the same day if at all possible. A clinical pathologist will complete cytology and hematology review as expeditiously as possible each day.
Equipment and Instruments

Canceling a Test
A specimen that arrives at the Clinical Pathology Laboratory and has not been processed may be canceled. If the ordered tests have already been performed when the cancellation notice is received, the routine fee for the test performed as originally ordered will be billed.
Repeating a Test
Clinical Pathology Laboratory tests will be repeated at no charge when the submitting veterinarian has good reason to question the validity of a test result. Please contact the laboratory and talk to the clinical pathologist on duty if you have questions about a possible erroneous test result.
