Laboratory Services

A simple blood test can check for the presence (or absence) of vital elements in your body, and it can let a doctor know if you’re fighting a disease. At Mary Greeley Medical Center, our full-service laboratory performs a variety of tests and screenings to help evaluate your health.

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.

Laboratory Services provides:

  • physician-ordered testing for both inpatients and outpatients at the hospital

When are blood tests done?

Most lab tests are collected between 4:30 and 6 a.m., although some patients need only a couple of blood tests during their stay. A patient being closely monitored may require a blood test two, three or four times a day. Most tests will take about an hour. For those tests that are sent to a reference lab, they may take 24, 48 hours or longer, depending on the test.

Who collects and tests my blood?

Your blood is collected and tested by professionally accredited members of the laboratory staff, overseen by a medical doctor specializing in the area of laboratory medicine.

When will results of my blood tests be available?

Your blood test results will be immediately available electronically to your physician as soon as they are finished. If your physician is not connected through our laboratory’s electronic medical record, the results can be faxed or mailed. Most tests that are performed at Mary Greeley Medical Center will take about an hour. For those tests that are sent to a reference lab, they may take 24 hours, 48 hours or longer, depending on the test. Your physician will share results of your blood tests.
