Subject Samples

The figures cover all subject profiles loaded to the National DNA Database as of 16th October 2009, it includes Criminal Justice (CJ), Police and Criminal Evidence (PACE), volunteer and reference samples. The figures are a profile count not individuals.

The number of subject profiles on the NDNAD is higher than the number of individuals because in some cases the NDNAD may hold more than one profile from a given individual.

Such replicate profiles arise from samples being taken from the same individual on more than one occasion.  This may happen as a result of a person giving different names, or different versions of their name, on separate arrests.  There may also be situations where a police force chooses to resample an individual.

It is currently estimated that as at 16 October 2009 13.8% of the subject profiles held on the entire NDNAD are replicates.

It is recorded solely for police intelligence purposes, to assist in subsequent identification of a suspect identified through a match on the NDNAD. Ethnic appearance has only been recorded for volunteer samples since 2005.
