Did you know that under normal
conditions, your body makes about 35ml
of blood each day? When we take a
blood draw, each test tube holds about 4 ml.

Mary Greeley Medical Center offers a full-service laboratory for tests. Our lab professionals do everything from simple wellness screenings to complex orders from specialty physicians in oncology, endocrinology, obstetrics and other medical disciplines. Our laboratory serves Mary Greeley Medical Center, our dialysis centers and McFarland Clinic.

The laboratory provides physician-ordered testing for both inpatients and outpatients at the hospital. Professionally accredited personnel are on duty around-the-clock to collect blood and conduct tests that are requested on an emergency basis.

Our laboratory offers a variety of tests to the public on a walk-in basis. The tests are confidential, offered for a small fee and do not require a physician referral. Get answers to other common questions about your lab tests at Mary Greeley Medical Center. 


We are easily accessible for outpatients with our first floor location near the front entrance and free valet parking. Please register at the reception desk of Laboratory Services.
