Question 1 of 30

A medical laboratory receives a request for a specific biochemical assay accompanied by a blood sample. Upon visual inspection, the phlebotomist notes that the sample appears to have been collected into an incorrect anticoagulant tube, which is not validated for the requested assay. The sample also exhibits signs of hemolysis. Considering the laboratory\'s commitment to quality and the requirements of ISO 15189:2022, what is the most appropriate immediate action to ensure the integrity of the testing process and patient safety?

Reject the sample, document the reasons for rejection (incorrect anticoagulant and hemolysis), and inform the requesting healthcare professional.

Proceed with the testing but add a disclaimer to the report indicating potential issues due to sample quality.

Attempt to re-collect the sample from the patient without informing the requesting professional.

Process the sample for the requested assay, assuming the incorrect anticoagulant will not significantly impact the results.
