What action should a phlebotomist take if blood test results are critical?

When a phlebotomist encounters critical blood test results, the priority is to ensure that healthcare providers are informed without delay. This is crucial because critical results often indicate potentially life-threatening conditions that require immediate attention. Prompt notification allows for timely interventions, which can significantly impact patient outcomes.

While rechecking test results may seem important to confirm accuracy, it does not address the immediate need for patient care and could delay necessary medical actions. Waiting for the next scheduled check-up would be unacceptable, as critical results necessitate urgent communication. Documenting and filing results is also essential but should follow the immediate notification to ensure that the healthcare team can respond swiftly to the patient's needs.

Thus, notifying the healthcare provider immediately stands out as the most urgent and appropriate action. This helps to facilitate rapid treatment or further diagnostic steps needed to manage the patient’s condition effectively.
