St. Peter's Health's Laboratory System

The laboratory is a full-service Joint Commission accredited laboratory consisting of two major services: clinical laboratory and anatomic pathology. The laboratory is staffed with accredited pathologists, licensed clinical laboratory scientists, phlebotomists, and support staff.

St. Peter's Health's Laboratory System offers a broad range of testing services including anatomic pathology, clinical chemistry, hematology, microbiology, blood bank, serology, and molecular diagnostics. It provides laboratory services for both inpatients at St. Peter's Health and outpatients in the greater Helena area.

Tests not performed at St. Peter's Health's Laboratory are sent to reference laboratories that are both approved by St. Peter’s Hospital Medical Staff and accredited through HCFA (CLIA) certification.
