Limit of Detection (LOD) :
Target copy number
Haploid genome copy number
Relative GMO content (%)
Number of repetitions
60 60,000 0.1 6 (ISO) or 10 (JRC)
40 60,000 0.07 6 (ISO) or 10 (JRC)
20 60,000 0.03 6 (ISO) or 10 (JRC)
10 60,000 0.02 6 (ISO) or 10 (JRC)
5 60,000 0.01 6 (ISO) or 10 (JRC)
0.1 60,000 - 6
- Independent dilutions (each level) of GMO DNA in non-GMO DNA- LOD = lowest level where 6 (or 10) repetitions give a positive result- 0.1 copy level : the number of positive results must be 1 (control of the method used to quantify DNA)

Quantitative analysis :
Specificity and LOD : idem qualitative analysis.Limit of Quantification (LOQ) :
Target copy number
Haploid genome copy number
Relative GMO content (%)
Number of repetitions
400 60,000 0.67 6 (ISO) or 10 (JRC)
300 60,000 0.50 6 (ISO) or 10 (JRC)
200 60,000 0.33 6 (ISO) or 10 (JRC)
100 60,000 0.17 6 (ISO) or 10 (JRC)
50 60,000 0.08 6 (ISO) or 10 (JRC)
0.1 60,000 - 6
Same principle as for LOD estimation but :- target copy numbers ~ 10 times higher- LOQ = level where RSDr 25 %

Quantitative analysis :
Linearity :- At least 5 levels prepared by independent dilutions of GMO DNA in non-GMO DNA (The dynamic range must cover the values corresponding to the expected use)
- For each level, 4 independent experiments and 2 PCR by experiment.
R2 = 1y = -3.22 x + 49.5
Calculation of :- R2 - slope
Performance of the method :- R2 ≥ 0.98- -3.1 ≥ slope ≥ -3.6 (ideally -3.32)

Quantitative analysis :
Accuracy (trueness and precision) :
Verification of analytical methods for GMO testing when implementing interlaboratory validated methods 07/2011 (http://gmo-crl.jrc.ec.europa.eu/guidancedocs.htm)
TruenessProcedure: The trueness should be determined at a level close to the level set in legislation (e.g. 0.9 %threshold), or according to the intended use of the method, and additionally at a level close to theLOQ.Testing conditions (reaction volume, PCR machine, etc.) should be the same as during routine testingof samples. At least results from 16 PCR replicates should be obtained. Acceptance criterion: The trueness shall be within ± 25 % of the accepted reference value or a Z-scorewithin the range of 2 and -2 should be obtained.
Precision - Relative Repeatability Standard Deviation (RSDr)Procedure: Repeatability can be determined in a similar way as described under Trueness. It iscalculated from PCR replicates run under repeatability conditions (see Terminology). Repeatabilityshould be available for all tested GM-levels.Testing conditions (reaction volume, PCR machine, etc.) should be the same as during routine testingof samples. At least 16 single test results should be obtained. Acceptance criterion: The relative repeatability standard deviation should be ≤ 25%, over the dynamicrange of the method.

Summary
Favorable context for the EU official labs :
- Validation of the methods by the JRC- Access to the methods- Access to certified reference materials- In France: access to guides helping the Implementation of new methods
Context of low contamination levels
But : only applies to events for which an application has been submitted.
