Some 183 crimes went undetected for up to 11 years because of Home Office failings over DNA samples.
They included one paedophile offence, three robberies, nine burglaries, 19 drugs offences and 62 thefts.
More than 26,000 DNA profiles were not added to the archive between 1995 and 2004, the National DNA Database's annual report disclosed.
Later investigation of these led to 85 suspects being identified for 183 crimes, a Home Office spokesman said.
