The inquiry into Queensland's state-run forensics lab has heard police DNA collection procedures could have affected the viability of samples in Shandee Blackburn's 2013 murder investigation.
A podcast into the woman's death prompted the inquiry and her case is in the spotlight at the hearings in Brisbane this week.
The inquiry is scrutinising the 2018 decision by the forensics lab and Queensland Police Service — the testing facility's major client — to classify DNA samples linked to major crime investigations as "DNA Insufficient for Further Processing", or DIFP, if they fell below a certain threshold.
