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.
