GE Products Affect our Grain Marketing Needs To distinguish biotech from conventional crops, we need tests that are: Accurate Reliable Cost-effective Market compatible
GE Rapid Test Kits Facilitate Testing Throughout the Grain-Handling System
Supports industry s demand for accurate and reliable test kits Provides increased consumer confidence Confirms test kit performance claims GIPSA s Biotech Test Kit Program
1. Manufacturer submits data package supporting their claims. 2. GIPSA staff reviews submitted data. 3. If the data package is complete and claims of the kit are supported by the data, GIPSA conducts performance verification. 4. If kit passes GIPSA performance testing, a certificate of performance (COP) is issued.
Control Samples 120 independent analyses, using three different test lots, 40 samples for each lot. All test results must be negative for the GE protein of interest. Fortified Samples 120 independent analyses, using three different test lots, 40 samples for each lot, at the claimed detection threshold. All test results must be positive for the GE protein of interest.
