More than 2,000 women have called the Cervical Check helpline.
It was set up over the weekend for women with concerns about their smear test results, after the case of Vicky Phelan who was incorrectly given the all-clear.
The line is open from 9.00am until 6.00pm this evening on on 1800-45-45-55.
The HSE says call-backs are underway.
It also claims its audit of 206 individual results is nearing completion will engage today with all women still awaiting contact.
The chairman of the National Association of General Practitioners, Dr Andrew Jordan, is urging women to continue to believe in the cervical check system.
"We're carrying out roughly 250,000 smears per annum, we're after reducing the incidents of cervical cancer by 7%.
"The other thing is that it's important not to forget (the) HPV vaccination programme here.
"One thing is the cervical check, but the HPV vaccine: it has the potential to wipe out cervical cancer".
