Introduction

Standard Operating Procedures (SOPs) are detailed, written instructions that describe how to perform specific tasks or processes consistently and correctly. SOPs are essential for ensuring quality, accuracy, and reproducibility in various settings, particularly in regulated environments such as clinical laboratories.

Internal audits are systematic, independent evaluations of an organisation’s processes, procedures, and systems to ensure compliance with established standards and identify areas for improvement. Internal audits play a crucial role in maintaining quality management systems and achieving accreditation under standards such as ISO 15189 and ISO 17025.
