Abstract

Background: Unqualified samples directly affect the accuracy of laboratory test results. Some links in the preanalysis stage are prone to produce unqualified samples that are difficult to identify, leading to inaccurate test results and affecting clinical diagnosis and treatment.
Methods: This paper reports a case of pseudo-lowering of blood routine results caused by improper blood collection operation.
Results: The blood routine samples caused by improper blood collection operation by nurses were diluted by the sealing solution of the indwelling needle, which resulted in inaccurate test results.
Conclusions: The laboratory should pay attention to the quality control in the preanalysis stage and identify unqualified samples in time, provide reliable diagnostic basis for clinical practice, and avoid the occurrence of adverse events.
