Laboratory Services

The Laboratory offers comprehensive services to inpatients, outpatients and emergency patients of all ages and is staffed 24 hours a day. Laboratory tests are analyzed using state-of-the-art instrumentation which is updated regularly. The Medical Director is certified by the American Board of Pathologists and, when not on site, is available on an on-call basis during off hours, weekends and holidays. Services provided include: chemistry, hematology, transfusion services, microbiology, urinalysis, histology, cytology and specimen collection.

Patient Ordered Tests:

The laboratory has a menu of specific tests that patients may order for themselves (direct access testing). These tests are general health screening tests that would be found at a health fair. Health panels, Liver, Kidney and Thyroid function panels, as well as Lipid, Iron and Diabetes assessment profiles are among the tests offered. Like health fair tests, these tests are offered at a considerable discount, but must be paid for prior to blood draw. Print off a copy of the order form or pick up a form at the Outpatient Registration desk at the hospital. The results of these tests will be reported back to you.
