The HSE has commissioned a 'rapid review' of the latest CervicalCheck controversy.
It will start immediately and will be finished in a 'timely manner'.
It emerged yesterday that about 800 women who had rechecks didn't get their results because of an IT problem with a US lab.
It centred on tests carried out from late last year, to June this year.
HSE chief executive Paul Reid says he has decided to commission an immediate rapid review of the controversy.
It will examine in detail how the communication process for providing results to women was planned and managed.
It will start commence quickly and be completed in a timely manner, led by a chairperson external to the HSE.
The HSE says while this review is ongoing, it will continue to update the women involved.
It will also work with Quest Diagnostics, the lab involved, to get to the bottom of what has happened.
