Welcome to this lecture on sterile technique in the lab, providing an overview of the principles and importance of sterile or aseptic technique in laboratory settings to prevent contamination. We will discuss essential practices such as hand hygiene, use of personal protective equipment, and validated sterilization methods. Techniques for maintaining a sterile environment, including use of biosafety cabinets and environmental monitoring will be outlined. Additionally, we will address the critical role of the pre analytical phase in ensuring reliable diagnostic results and minimizing errors. Sterile or aseptic technique is the cornerstone of laboratory practice where contamination risks must be rigorously controlled. In settings such as cell culture work, biopharmaceutical production, and diagnostic sample preparation, the main goal is to prevent unwanted microorganisms. This is essential for valid reproducible results and for ensuring the safety of staff and patients. Rigorous sterile technique requires understanding hand hygiene, proper personal protective equipment use, and adherence to validated procedures. Sterile technique relies on universal precautions and habits that limit contamination. Hand hygiene is essential. Thorough washing before and after procedures and using suitable disinfectants like alcohol based rubs minimizes microbial transfer. Gloves must be changed between processes or if contamination is suspected, personal protective equipment such as lab coats,
