AOAC Method SMPR 2017.020 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Quantitation of Chicken Egg by ELISA-Based Methods

AOAC SMPR 2017.020 establishes method performance criteria for detecting and quantifying chicken egg proteins in various food products using ELISA-based methods. The method supports allergen labeling and requires analytical sensitivity to detect egg proteins within an analytical range of ≥5 to ≤10 ppm. Both the limit of detection (LOD) and limit of quantitation (LOQ) must be ≤5 ppm. Acceptable recovery ranges from 50% to 150%, with a repeatability (RSDr) not exceeding 20% and reproducibility (RSDR) not exceeding 30%. Instruments must support precise absorbance readings at 450 nm and stable incubation temperatures near 37 °C to meet these performance requirements.

To meet AOAC criteria, laboratories must use reliable, validated microplate readers and incubators that deliver consistent results with minimal well-to-well variation. Photometers should offer robust optical performance and support for 96-well plates. Incubators should avoid fan-based convection, which may disrupt assay performance. The following platforms provide strong reproducibility, user-friendly software, and compatibility with allergen testing protocols. These systems do not imply AOAC endorsement but satisfy the method’s analytical and operational requirements.
