Maryland COMAR 10.10 Changes: What Clinical Laboratories Need to Know

Effective March 1, 2026, Maryland updated COMAR 10.10.01 through 10.10.08 and 10.10.12 — the state regulations governing clinical laboratories. If your lab operates in Maryland, these changes affect how you handle waived testing, quality control, and state-level compliance documentation.
The Biggest Change: CLIA-Waived Tests Are Now Automatically 'Excepted'
Under the updated COMAR 10.10, tests that CMS classifies as CLIA-waived are now automatically categorized as 'excepted' at the state level. This eliminates what had been a confusing dual-classification system where labs sometimes needed separate state approval for tests that were already federally waived.
For most labs, this simplification is welcome. But it also means your QC requirements for waived tests now default to manufacturer IFU (instructions for use) only — no additional state-mandated QC beyond what the manufacturer specifies.
QC for Waived Tests: Follow the Manufacturer
The updated regulations clarify that quality control for waived tests must follow the manufacturer's instructions for use — no more, no less. This aligns Maryland with the federal CLIA framework under 42 CFR Part 493 and eliminates any ambiguity about whether state rules required additional QC beyond what the manufacturer specified.
What this means in practice: if your rapid strep test manufacturer says to run a positive and negative control once per new kit lot and once per new shipment, that is your QC requirement. You do not need to run daily controls unless the manufacturer specifies it.
What Didn't Change
Maryland's regulations for moderate and high-complexity testing remain largely unchanged. Personnel qualifications, proficiency testing requirements, and quality assessment standards under COMAR 10.10 continue to mirror the federal CLIA framework. If your lab only performs moderate or high-complexity testing, the March 2026 updates have minimal operational impact.
Action Items for Maryland Labs
Review your waived test menu and confirm that your QC practices match the manufacturer's IFU — not an outdated internal policy that may have been more conservative than required.
Update any SOPs that reference the old COMAR 10.10 classifications or impose state-specific QC requirements beyond the manufacturer's IFU for waived tests.
Verify your Maryland OHCQ documentation reflects the current 'excepted' designation for all CLIA-waived tests you perform.
Brief your point-of-care testing coordinators on the change — they manage the bulk of waived testing in most health systems.
The Bigger Picture
This COMAR update is part of a broader trend: states aligning their laboratory regulations with the federal CLIA framework rather than maintaining separate, sometimes conflicting requirements. For multi-state laboratory networks and reference labs serving the DMV region, this simplification reduces the compliance burden.
But simplification does not mean you can ignore it. If your SOPs and QC documentation still reference the old COMAR language, you have a documentation gap — and documentation gaps are exactly what surveyors look for.
