Leonardtown, Maryland – Patients who arrive at MedStar St. Mary’s Hospital for outpatient lab work will now report to the Outpatient Pavilion on campus instead of the current laboratory located in the main hospital.

A private registration office for the Outpatient Pavilion Laboratory Center is located on the ground floor of the Pavilion adjacent to the Imaging Suite, with a lab draw area on the second floor across from the elevators. Appointments are not necessary for general blood testing, however, an appointment is required for glucose tolerance tests, semen analysis and DNA testing.

For LabCorp and Quest Diagnostics services, patients may visit the hospital’s three satellite laboratory locations throughout the county: the St. Mary’s Medical Center in Charlotte Hall, the Chesapeake Charter School in Great Mills, or the Belmont Building in Leonardtown.

Outpatient Pavilion Laboratory Center hours are 7 a.m. to 6 p.m., Monday through Friday, and 7 a.m. to noon on Saturdays. For more information, visit MedStarStMarys.org or call 301-475-6133 or 240-434-7497.
