Quality assurance is the tool that enables the clinical analysis laboratory to provide reliable, appropriately and correctly interpreted results. Calibrators are used in the routine of these laboratories, which are known standards with determinated quantitative and / or qualitative characteristics used to calibrate, calibrate, or adjust a measurement procedure. Control are used for multiparameter calibration at the same time and should be used in accordance with manufacturer's recommendations. Calibrator performance may be affected by reconstitution, homogenization, improper storage, water contamination, or glassmaking errors. Thus, this work evaluated the stability of commercial control submitted to different temperatures in real laboratory situations, such as refrigeration between 4-8 ºC, exposure under a working bench, at room temperature, and stored inside a car, at temperatures of 60-80 ºC, for periods of 1 to 12 days. Both the time and the temperature at which the aliquots are stored did not cause changes in this product (except for creatinine, which was unstable on the 12th day of the study), presenting values within the estimated ranges, and possibly the aliquots outside the estimated ranges follow a systematic error.
