Resumo

The Reference National Laboratory, Genes Ltda, designated by the Commission of Accreditation and Alertness created by Law 721 of 2001 of Republic of Colombia, organized and coordinated the Quality Control Exercise of 2008 for laboratories undertaking paternity and maternity tests with DNA markers. The Quality Control Exercise included both practical and theoretical exercises. For the practical exercise, three blood samples in FTA Classic Card were sent to each participating laboratory to be genotyped for DNA markers using the routine methodologies in their laboratories. For the theoretical exercise, it was asked to the participating laboratories to calculate the partial and final paternity indexes based on two genetic profiles of an alleged biological father and his son. Allele frequencies were made available to the participants, as well as Y chromosome haplotype database. A total of 12 laboratories have participated with data from 57 STRs, including autosomal and sex chromosome markers. Consensus was found in 37 STRs, 21 in autosomes and 16 Y chromosome linked. The rate of reporting errors was 3.1% (concentrated in just one laboratory). The theoretical exercise had consensus.
