The name of the UK NEQAS for GFR Estimations Scheme has been changed to UK NEQAS for Acute and Chronic Kidney Disease to include the newly accredited analyte AKI. You can participate in either, or both, the AKI and CKD elements of the Scheme.

Due to the nature of the AKI element of the Scheme which looks at historical data, there will be, by necessity, restricted time points where you can join. New participants to this Scheme will be able to join:

  • Up to 1st May 2023 and will receive specimens from Distribution 198
  • Up to 1st June 2023 and will receive specimens from Distribution 199
  • Up to 1st Sept 2023 and will receive specimens from Distribution 202
  • Up to 1st Oct 2023 and will receive specimens from Distribution 203
  • Up to 1st Feb 2024 and will receive specimens from Distribution 206

Please contact Birmingham Quality if you have any questions or view our AKI presentation for more information.
