Question: I ordered a test as STAT for collection but it was not processed STAT. Why?
Context: STAT testing can be requested when results are urgently required for immediate patient care or a true medical emergency. However, STAT collection and STAT processing are not the same thing in acute care facilities. While any test can be ordered as STAT for collection, only tests on the Acute Care Facility STAT Testing List are automatically processed STAT without additional approval. This list was standardized provincially in 2025 (see lab bulletin New Provincial Stat List for Acute Care Facilities). There are no departmental exceptions to this rule, e.g., specimens from Emergency Departments are not processed STAT unless they are both ordered as STAT and the test is on the approved list.
In addition, for tests on the STAT List, final turnaround time will depend on where the test is performed:
- On-site testing: Collected and performed STAT, with an expected turnaround time of 90 minutes.
- Off-site testing: STAT collection occurs, and STAT transport may be arranged depending on clinical urgency, test type, location, and prior arrangements with the laboratory.
- Performing departments and testing locations are listed in the APL Test Directory.
Answer: If a test ordered as STAT for collection is on the STAT List, it will be automatically processed STAT without additional approval. If a test ordered as STAT for collection is not on the STAT List:
- STAT collection will occur; however, STAT processing is not automatic.
- Approval for STAT processing must come from the laboratory medical/scientific staff (e.g., General Pathologist, Microbiologist, Chemist) at the performing department (listed in the APL Test Directory).
- To obtain approval for STAT processing, the prescriber must call the appropriate laboratory medical/scientific staff via:
- Calgary & Edmonton Zones: Use the Regional On Call Application (ROCA).
- Central, North & South Zones: Call via the facility switchboard.
