Queensland victims of crime are waiting to find out if their cases will be reviewed after a damning report into the government-run forensic lab.

A four-month inquiry into the state's embattled DNA testing system found it failed to properly test DNA samples for years because of "grave maladministration involving dishonesty".

The report revealed lab managers had focused on speed rather than accuracy in DNA testing, and "that scourge has invaded" the validation of process and equipment used, time management and resources.

Former judge Walter Sofronoff recommended Forensic and Scientific Services be restructured with an independent head scientist focused on scientific integrity and serving the criminal justice system.

Potentially "thousands of cases" could be reviewed, and crime scene samples retested for DNA, potentially by a panel including a scientist, a police officer, a prosecutor and a lawyer.

The Queensland government is expected to respond to the findings on Thursday.
