Around 200 women will have to take another smear test after their results went out of date.
The HSE says the results expired due to covid-19 restrictions and huge demand on CervicalCheck.
HPV was detected in each of the impacted women's smears.
They should have gone for further examination to check if there were any precancerous cells present.
However, this couldn't be done within the required 42 days and so the women affected will have to be retested.
The HSE says the test results went out of date because of a delay in the CervicalCheck processing centre in Santry in Dublin due to covid restrictions and an unprecedented number of samples in the first half of this year.
The HSE says it’s important to note that cervical cancer is a rare outcome of a HPV infection and the women affected will be prioritised.
It's apologised for any inconvenience and worries this delay may have caused.
Anyone concerned can call the National Screening Service number on 1800 454 555.
