Abstract
Background: On an initial urine screening test for illegal substances, if the concentration of a substance is at or above the determined legislative threshold, it is reported as positive. Repeating testing with the same sample to verify it before reporting is a common practice in clinical laboratories. This study aimed to determine whether measurement uncertainty (MU) results can be used to detect a grey zone to reduce repeat testing.
Methods: A retrospective study was conducted using data from the laboratory information system between January 1, 2020, and July 1, 2022. Samples studied twice within one hour before reporting for the same urine sample were analyzed. The MU values for urinary amphetamine, cannabinoid, cocaine, and opioid parameters were calculated using ADVIA Chemistry reagents on a Siemens ADVIA 1800 chemical analyzer. The grey zone was defined as the cut-off value ± MU.

clinical and medical biochemistry,
molecular medicine,
clinical hematology and coagulation,
clinical immunology and autoimmunity,
clinical microbiology,
virology,
clinical genomics and molecular biology,
genetic epidemiology,
drug measurement,
evaluation of diagnostic markers,
new reagents and laboratory equipment,
reference materials and methods,
reference values,
laboratory organization,
automation,
quality control,
clinical metrology,
all related scientific disciplines where chemistry, biochemistry, molecular biology and immunochemistry deal with the study of normal and pathologic processes in human beings.
