The first is the minimization of human error and other pre-analytical errors. As these controls are ready-to-go out of the box, there is no chance of reconstitution errors, which can result in deviations from the target values and contamination, which could lead to problematic cross-reactions. Smart QCs reduce the risk of stability issues resulting from aliquoting or the repetitive opening of vials, and eliminate the possibility of mislabelled controls, while freeing up more cold-storage space.

Smart controls also offer the possibility of improvements in other areas of the laboratory. The reduced preparation required for these controls allows laboratories to use this time improving other elements of their QC practices, such as QC analysis and process improvement. Fewer steps in the QC process not only means time saved in the process itself, but also less paperwork for the laboratory staff, further freeing up time for more useful practices. Workflow efficiency can also be improved through consolidation of analytes. Smart controls that effectively consolidate many analytes, while maintaining suitable stability, reduce the number of controls required.

Immunoassay smart QCs provide laboratories with an effective QC solution, which aids in the optimization of workflows and the reduction of test turnaround times and the risk of human error throughout the QC process. However, if considering a smart QC for your laboratory, it is important to remember the other factors too, which make a good QC including matrix, stability, and clinically relevant concentrations.
