Our Laboratory Services Department is responsible for all blood and body fluid testing ordered by your provider. Because approximately 70% of all medical decisions are based on laboratory results, we are committed to providing the highest degree of accuracy in our lab testing.

The McKenzie Health System Laboratory Services Department has been accredited by the College of American Pathologists (CAP) since 1996. This accreditation is the gold standard in laboratory accreditation. Compliance with CAP regulations assures accuracy in patient results, giving your provider the confidence to prescribe the correct treatment.
