Cervical screening sample takers PIN error

25 February 2026

Since 1 January 2025, all NHS cervical screening samples sent for processing to Cervical Screening London (CSL) laboratory must include the sample takers’ London Cervical Sample Taker Database (LonCSTD) Personal Identification Number (PIN). All NHS Cervical Screening sample takers, including trainees practising in London must:

  • be correctly registered on the LonCSTD held and managed by CSL laboratory
  • use their unique sample taker LonCSTSD Personal Identification Number (PIN) for all cervical samples taken in London
  • ensure they have uploaded their original training and 3-yearly update certificates onto their LonCSTD account in a timely manner
  • respond to all communication from CSL regarding PIN errors within 48 hours to ensure the requested sample does not trigger the zero-tolerance policy.
