LAB = the code number for each evaluated laboratory. EQA = External Quality Control Evaluation. EQA1 was performed in 2003, EQA2 in 2005, EQA3 in 2006, EQA4, in 2007, and EQA5 in 2008. NA = not available due to the absence of participation of a specific laboratory in the network or in the evaluation. % > 80 refers to the percentage of participating labs that scored more than 80 points. Laboratories that were not able to PCR amplify both samples received a score equal zero.
