Quality control is a cornerstone of credibility in diagnostic laboratories and healthcare environments. The reliability of laboratory results directly influences clinical decisions, patient safety, and the overall trust placed in diagnostic services by hospitals, clinicians, and research institutions. Well-structured quality control systems ensure that laboratory processes operate consistently, accurately, and in alignment with established quality frameworks. Through internal

Internal Quality Control (IQC) is a fundamental component of reliable diagnostic laboratory operations. It plays a critical role in ensuring that analytical processes remain stable, consistent, and capable of producing accurate results on a daily basis. Internal quality control processes ensure stability, accuracy, and consistency in daily diagnostic laboratory operations. Through structured internal quality control procedures, laboratories continuously monitor the performanc

External Quality Assessment (EQA) is a critical element of quality assurance in diagnostic laboratories, providing independent verification of analytical performance. While internal quality control ensures daily process stability, external quality assessment confirms that laboratory results remain accurate and comparable within a broader diagnostic framework. Through participation in external quality assessment schemes, laboratories evaluate their performance against predefin
