An independent review has concluded that controversial technique for obtaining DNA profiles from tiny samples is scientifically sound.The study, commissioned by the Government last year after doubts were raised over the reliability of low template DNA testing, made a series of recommendations for improving the collection and interpretation of samples.

The Police Service of Northern Ireland suspended its use of LCN testing after the Omagh trial but the technique continued to be used by prosecutors in England and Wales.

Professor Brian Caddy, who led the review, said the technique is fundamentally safe, but is not being used as effectively as it might.

Low copy number (LCN) DNA testing - a particular technique within LT analysis - hit the headlines last December when the judge in the Omagh bombing trial questioned its scientific validity.

Mr Justice Weir expressed doubts over LCN testing after it wrongly linked a sample taken from a car bomb in Northern Ireland to a 14-year-old boy in Nottingham.
