The Cervical Sample Takers Database (CSTD) has been designed for the quality assurance of cervical sample takers. All cervical sample takers in Cumbria, Greater Manchester, Lancashire and Cheshire & Mersey will need to be registered on the system to ensure the laboratory holds a centralised list of all sample takers working in these areas and can provide up-to-date information on each sample taker's performance data and training.


The success of the Cervical Sample Takers Database relies on the users accepting and undertaking their assigned responsibilities. All users must ensure that any information they record on the database is accurate and they should ensure that the database is kept up-to-date following new user creation or any changes at later stages. It is important that the database is accessed by users regularly to monitor sample taker performance so any areas of concern can be high-lighted, and steps can be taken to resolve the problem quickly, reducing the risk to patients.

  • AMBER = 1% – 4% of samples rejected
  • GREEN = 0% of samples rejected
