Medical laboratory staff examining specimens in test tubes

We provide  an extensive range of diagnostic laboratory testing for inpatients and hospital outpatients. Our medical laboratory technologists and technicians perform and/or prepare sophisticated laboratory tests on blood, body fluids and body tissue. Our laboratory physicians facilitate diagnoses.

Your physician’s decisions regarding diagnosis and treatment are often based on laboratory test results.

We are committed to providing quality, timely and reliable service to our community. We pursue excellence in providing diagnostic information and services and act as a resource and facilitator by educating our customers in the appropriate testing strategies and utilization of our services.
