Countries may run risk-based lot verification of Class D IVDs, before distribution, after distribution or before use, through a designated national reference or other competent laboratory, to confirm that each lot satisfies the requirements set for it on safety, quality and performance, and that shipping and storage have not affected performance. The need depends on the other controls in place, such as stringent transport and storage control and effective quality control in the receiving laboratory.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
