It would be lawfully possible to collect DNA samples from survivors of the Mother and Baby Home in Tuam, according to a new report.
Children's Minister Katherine Zappone has published a report from Dr Geoffrey Shannon's investigation into the issue.
The minister commissioned the report last February, shortly after calls for the state to begin collecting DNA samples immediately in light of the age and declining health of many survivors.
Dr Shannon says there's no reason, in principle, why an appropriate administrative scheme could not be established.
But he says it's not clear whether it would possible to generate profiles from juvenile human remains that would match family members.
Minister Zappone says she hopes to develop a voluntary administrative scheme in the coming months.
