So that collection and storage before examination are safe, accurate and suited to the clinical need, instructions shall be issued by the laboratory covering: confirming who the patient is; checking and recording that preparation requirements are satisfied (for example fasting, when medication was taken, timed collections); how primary samples are taken, including containers, additives and draw order; labelling so that each sample links to its patient without ambiguity; recording who collected the sample, on what date and, where it matters, at what time; separating or splitting the sample; stabilising and storing it until it is delivered; and disposing safely of collection materials.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
