Getein Quality Control (QC) Solutions are designed to monitor and evaluate the analytical and clinical performance of diagnostic devices. They provide both internal quality control (IQC) for daily laboratory monitoring and external quality assessment (EQA) for cross-laboratory comparison. QC solutions are formulated to closely match patient sample matrices, ensuring uniformity and stability. These solutions are essential for improving laboratory quality management, detecting systematic issues, and identifying training needs. The QC methods follow Westgard rules, including L-J QC and X-B QC for precise monitoring of fluctuations within ±2 SD.
