After-Hours STAT Specimen

The Clinical Laboratories provides 24/7 service for many tests to meet the clinical needs of our providers. Days performed and turnaround time is noted for each test in the UW Hospital and Clinics Lab Test Directory.


There may be exceptional circumstances when there is a clinical need for testing to be completed outside of the routine schedule. For clinicians requesting STAT services after hours, pathologist approval must be obtained before testing will proceed. The pathology resident will confer with the clinician to confirm the testing is needed stat because the test result will impact the clinical care provided the patient.


Testing that requires pathologist approval after hours is noted in the Lab Test Directory. For example, in the entry for Pentobarbital (PENT) see the note "Pathology Resident approval is required after hours" in the Days Performed field.
