Where no suitable external program exists, internal quality assurance fills the gap across all three phases: high-risk areas of collection and testing are compared with other accredited laboratories; result validity is shown by testing reference material or by comparing across laboratories, for instance through sample exchange; and diagnoses are compared through peer review, whether by swapping slides under a formal scheme or by seeking a second opinion, formal or informal.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
