CueSee Glucose from Eurotrol is a real blood control for validating the precision and accuracy of glucose meters. Its real blood matrix makes the control highly commutable and compatible with all glucose devices with minimal matrix effects and precision similar to human whole blood. The dual-chambered ACU-Drop II packaging device keeps the various fractions separated to prevent reactions between components of the desired matrix. Users simply push a button, the fractions combine, and the mix and the sample are ready to use either from the built-in dropper or by attaching a syringe. The control can be used for QC, calibration verification, proficiency testing, competency assessment, method validations, and lot comparisons.
