The laboratory result is 6.0 mg/dL above the peer consensus.
The lab value is 1.5 standard deviations above the peer mean.
An SDI of +1.50 falls comfortably within the acceptable analytical range (|SDI| < 2.0), reflecting normal interlaboratory variation.
| Input Scale | Standard Output Range | Variance Band | Recommendation |
|---|---|---|---|
| Low Baseline | 0.00 – 25.00 | ±1.5% | Optimal for conservative estimations |
| Median / Standard | 25.00 – 100.00 | ±0.8% | Benchmark standard for commercial workflows |
| Elevated / High | 100.00 – 500.00 | ±0.4% | Recommended for high-throughput modeling |
| Extreme Maximum | > 500.00 | ±0.1% | Verify input constraints for boundary saturation |

An SDI magnitude |SDI| ≥ 3.0 indicates statistically significant bias (>3 SDs away from peer consensus) and is considered unacceptable, requiring immediate investigation and corrective action.
An SDI of 0.0 indicates perfect agreement with the peer group consensus. Any result with |SDI| < 1.0 demonstrates excellent analytical performance.
SDI assesses analytical accuracy and systematic bias relative to peer consensus, whereas CVI (Lab CV / Peer CV) assesses precision and internal repeatability relative to peers.
