Women with cervical cancer - who are having their smear histories reviewed - will find out next week if the results are at odds with what they were originally told.
Over one thousand women consented to have their slides reviewed.
Next week the women concerned will receive the results of the review - which is being carried out the Royal College of Obstetricians and Gynaecologists.
Over 1000 women who had smear tests through CervicalCheck - but went on to develop cancer, consented to their slides being reviewed.
Cervical Check audits initially found that 221 women were given incorrect results, but the figure is likely to increase significantly.
The women concerned will receive letters from both the Royal College of Obstetricians and Gynaecologists and the HSE this week advising them what their options are in terms of receiving the results and what supports will be made available to them.
