Standard Operating Procedures (SOPs) provide detailed step-by-step instructions for carrying out a laboratory activity in a manner that obtains accurate and reliable results and ensures biosafety. SOPs are used in the laboratory and written copies should be available (preferably displayed) at the work area or bench. They are important for the standardization of procedures, ensuring that every laboratory at each level of care performs national standard procedures and produces high quality results.
