The HSE has revealed that more than 2,300 women are still waiting on repeat smear test results.
This follows an issue with HPV (human papillomavirus) tests that were carried out beyond the 30-day recommended timeframe by US-based laboratory Quest Diagnostics between 2015 and 2018.
The lab is blaming a technology system, which it says took longer than expected to set up.
At the end of January, CervicalCheck wrote to some 4,459 women inviting them to have a repeat smear test.
The HSE has said Cervical Check's clinical team is assured that these HPV tests are likely to remain effective outside the manufacturer's recommended timeframe, "and that the risk of incorrect results is low".
However, it added that those invited to attend for a repeat smear test were told to do so "in order to provide complete reassurance".
Since 8 February, 2,572 repeat smear test samples have been received by Quest Diagnostics. According to the Health Service Executive, they have been coming in incrementally since.
In a statement, the HSE/CervicalCheck said that a Quest information technology system for dealing with the repeat tests took longer than expected.
"Quest is confident that the remaining results will be reported to women within the next two weeks", the HSE said.
Just last week, a press release issued by the HSE stated that system amendment recommendations in the Scally report are "on track and progressing well and apace.
"Work has been on-going since September, with participation from clinicians, managers, staff and patients across our health system to progress 94 separate actions arising from the Scally Review."
The report by Dr Gabriel Scally also examines the tendering, contracting and operation of the labs contracted by CervicalCheck.
According to Dr Scally, the biggest failure he identified in his four-month review was the non-disclosure of information from CervicalCheck audits to patients.
