There are four national Blood Services/Blood Transfusion Services in the UK:
These are Blood Establishments.
Following devolution of governments in the UK, the UK Blood Services Forum was established in 1999 comprising the chief executives and medical directors of the four services, and JPAC became accountable to the medical directors, who themselves are accountable to their chief executives. The close working relationship with NIBSC (subsequently part of the Medicines and Healthcare products Regulatory Authority (MHRA) from April 2013) has been maintained through the Director of NIBSC.
