The number of profiles added to the National DNA Database (NDNAD) for each quarter of the last five years is set out in the following table . It is currently estimated that 13.7 per cent. of profiles held on the NDNAD are replicates, i.e. that a profile for a person has been loaded on more than one occasion (one reason for this is that the person gave different names, or different versions of their name, on separate arrests). Thus, the number of individuals on the database is approximately 13.7 per cent. less than the number of subject profiles. The presence of these replicate profiles on the NDNAD does not impact on the effectiveness and integrity of the database. Nonetheless, a long-term exercise is under way to identify issues associated with the removal of all such redundant replicate profiles.
