What the regulation sets, and what it leaves to you

Task	Interval	Source
Calibration verification	At least once every six months, and after the events the regulation lists	42 CFR 493.1255(b)(3)
Accuracy check for tests with no required proficiency testing	At least twice a year	42 CFR 493.1236(c)(1)
Laboratory director on-site visit (moderate and high complexity)	At least once every six months, at least four months apart	42 CFR 493.1407(c), 493.1445(c)
Competency assessment	Twice in the first year a person tests patient specimens, then yearly	42 CFR 493.1413(b)(9), 493.1451(b)(9)
Proficiency testing	On your program's event schedule	42 CFR 493.801
Quality assessment review	Ongoing. No interval is set, so your plan sets one	42 CFR 493.1239, 493.1249, 493.1289, 493.1299
Review of procedures	No interval is set. Approval by the current director is required before use and after any change	42 CFR 493.1251(d)

The proposed rule published in October 2026 would remove the director's on-site visit requirement. It is not final, so the visit is still required. See the 2026 proposed rule.

These are federal minimums. Your state, your accreditation organization or your own policy may set shorter intervals. Maintenance and quality control follow each manufacturer's schedule and are not included here.

The forms for these tasks are in the kits: calibration verification, proficiency testing and accuracy checks, monthly quality assessment review and competency assessment.
