Clinical Labs in Ravalli County

Welcome to the Marcus Daly Laboratory Department. Our primary lab has been conveniently relocated to a central location within the hospital to allow for better communication and faster turnaround. We also manage many multiple satellite locations throughout Ravalli County so local residents can have access to a convenient location close to home.

The Marcus Daly Laboratory Team is comprised of ten scientists, each having their Bachelor of Science degree, as well as a support team highly-skilled in customer service, specimen processing, and phlebotomy. The Laboratory’s Medical Director is a Pathologist who provides bi-monthly onsite reviews, is available for consultation, and assists the Imaging Department with fine needle aspirations. Collectively, the Marcus Daly Laboratory team has over 200 years of experience. Each clinical team member has a National Registry certification by either the American Society of Clinical Pathology (ASCP) or the American Medical Technologists (AMT).

What Does a Clinical Lab Do?

Where did the blood sample go that I gave in the doctor's office? How did my doctor diagnose my disease? How did my doctor confirm that my cholesterol was high or my thyroid was not working or that I was having a baby? These are just a few of the issues addressed by the Marcus Daly Memorial Hospital laboratory.

The Laboratory team works together while operating sophisticated technology and instruments to determine confirm, rule out, or aid in a diagnosis. They also provide specimen testing and can help monitor treatment to ensure it is working as expected.

Our lab technicians are medical professionals who work quickly and precisely. The information they give to the medical provider influences 70% of the medical treatment a patient receives. They are vital members of the health care team, and play a critical role in collecting the information needed to give the best care to a sick or injured patient.
