All Duty Biochemists or shift duty Medical Technologists shall follow this procedure.  \n2. The test (s) requested for reporting location equipped with the Critical Result Alarm System (CRAS) will be automatically alerted ofall critical laboratory results listed in Table 1.  \n3. If the CRAS alert is not acknowledged within 10 minutes, the alert will be bounced back to PWH Chemical Pathology Laboratory. For reporting location without CRAS, bounce-back alert will be triggered to PWH Chemical Pathology Laboratory. The critical laboratory result(s) will then be phoned through by the Rapid Response Laboratory staff to either clinician or nurse.  \n4. Identify the patient with name, HKID, bed number and collection time of specimen before phoning the critical result(s) .  \n5. Ensure that the results are correctly recorded and advise clinician / nurse to retrieve the result via electronic patient record.  \n6.
