A CAP inspection feels different from a CMS survey — and labs that understand the difference walk in calmer. Here's what inspectors are actually doing.

They work from checklists. CAP publishes detailed checklists by discipline. Inspectors verify each applicable requirement — and they expect you to know which checklist items apply to your lab. Doing a self-inspection against the current checklists is the single best preparation.

They use tracer methodology. Instead of only reviewing documents, inspectors trace real specimens through your entire process — from order to result reporting — interviewing staff along the way. If the people doing the work can't describe the process the way your SOPs do, that's a deficiency.

Proficiency testing gets scrutinized. PT enrollment, performance, and — critically — what you did about any failures. A PT failure with a documented root-cause investigation and corrective action is manageable. A PT failure nobody investigated is not.

Personnel qualifications matter. Inspectors verify that everyone performing high-complexity testing meets the personnel requirements, and that competency assessments are current and meaningful — not just signed forms.

They expect a culture of quality. The unifying theme: CAP inspectors look for a lab that finds its own problems. Robust internal audits, real corrective actions, and management review all signal a lab that's inspection-ready every day, not just on inspection day.
