Abstract

Background: Unqualified samples directly affect the accuracy of test results in clinical laboratory. Timely and accurate identification of unqualified specimens can avoid the occurrence of medical adverse events.
Methods: This study reported a case of abnormal results caused by urine carrying contamination in serum during detection.
Results: During the testing process, improper operation of laboratory staff led to serum contamination with urine, which affected the accuracy of the test results.
Conclusions: In addition to the pre-inspection stage, all laboratories should also pay attention to the quality control of sample during the inspection, so as to ensure the accuracy of the results and medical safety.
