Verification Toolkit Bundle – Precision, Accuracy, Reportable Range, Reference Interval, Includes SOP Template for New Method Verification

Running a small or independent lab means you're responsible for full regulatory compliance — without a team of quality managers to back you up. Before you report a single patient result on any non-waived test, CLIA (42 CFR §493.1253), CAP, and COLA require you to verify that your method actually performs the way the manufacturer claims. Miss any one of those verifications and you're out of compliance on day one.

Most labs solve this by paying for EP Evaluator or similar software — a recurring cost that doesn't make sense for a lab running a handful of assays. This toolkit gives you everything you need in Excel and Word, ready to fill in and file.

What's Included (5 Documents)

1. Precision Verification — CLSI EP15-A3 Verifies that your instrument's repeatability and intermediate precision meet the manufacturer's published claims. Supports 3 control levels, a proper 5-day × 2-run × 2-replicate study design, and calculates both within-run SD and total precision SD automatically. Includes the rigorous EP15-A3 chi-square verification method alongside the simpler CV% comparison — satisfying even the most thorough CAP inspector.

2. Method Comparison & Bias Estimation — CLSI EP09-A3 Demonstrates that your new method agrees with a reference method across the full reportable range. Supports 40 paired patient samples, calculates mean bias, SD of bias, 95% confidence intervals, and regression statistics (slope, intercept, R²) automatically. The 95% CI — not just the mean — is used as the pass/fail criterion, which is the statistically correct approach per CLSI.

3. Analytical Measuring Range (AMR) Verification — CLSI EP06 Confirms your instrument can accurately measure and report patient values across the full manufacturer-claimed reportable range. Evaluates both linearity (slope, R²) and percent recovery at up to 8 concentration levels. Includes an AMR Span Coverage Check that documents how close your lowest and highest linearity materials come to the actual AMR limits — a detail often flagged during CAP surveys.

4. Reference Interval Verification — CLSI EP28-A3c Verifies that the manufacturer's stated reference interval is appropriate for your patient population. Applies the EP28-A3c simplified 10% rule — the standard CLIA/CAP-accepted approach for FDA-cleared assays — using a minimum of 20 reference individuals. Automatically flags results outside the interval, counts outliers, and delivers a clear verified / not verified conclusion.

5. Generic Laboratory SOP Template A fully structured, CLIA-formatted Standard Operating Procedure template covering every required section: purpose, principle, specimen, equipment, reagents, calibration, quality control, step-by-step procedure, calculations, results interpretation, reference range, reporting, limitations, and related documents. Pre-linked to the verification templates in the Related Documents section. Works for both analytical test methods and non-analytical laboratory processes.

Every Template Includes:

• CAP · COLA · CLIA §493.1253 compliance statement

• Configurable acceptance criteria sourced from the manufacturer package insert

• Automatic Pass / Fail determination at each step

• Lab director attestation and signature section

• Detailed instructions explaining when to use it, how to design the study, and how to interpret results — written for the person actually doing the work, not just the inspector

Designed For: Small and independent clinical laboratories, physician office labs (POLs), and urgent care labs performing non-waived, moderate complexity testing who need to demonstrate compliance without expensive software subscriptions.

All templates are provided as unlocked Excel (.xlsx) and Word (.docx) files. Compatible with Microsoft Excel 2016 and later, and Microsoft Word. Not intended for high-complexity or laboratory-developed test (LDT) validation — these are verification templates for FDA-cleared assays only.
