Pre-analytical errors

Hemolysis

The corrective action

The sample must be rejected and another sample be obtained.

Post-analytical errors

reports were sent to the incorrect patient

If the patient’s gender is written wrong in the report, the reference range was written incorrectly

The corrective action

communication with patient, apologising for the error, and providing him

with the correct report

If the report is not delivered to the patient and this error is discovered, fix it, but if the report is delivered to the patient, apologise to him, tell him that an error has occurred, and replace it with the correct report.

And next time, be careful when you write down the gender and reference range
