Life-saving patient care

Therapeutic Apheresis is one of our flagship services, and the only one that deals with patients directly. We treat approximately 1,600 adults and children every year from 10 dedicated therapeutic units across the country.

The information on these pages is primarily for Therapeutic Apheresis patients, donors, carers and visitors.

TAS Connect

We are proud to announce that we are improving the process for clinicians referring patients to the Therapeutic Apheresis Service (TAS) by introducing a new platform, TAS Connect, this Winter.

TAS Connect will improve the patient experience by simplifying the referral process for clinicians, through the online portal. It will also support better outcomes for patients by introducing additional safeguards and clinical prompts to ensure referrals are accurate.

TAS Connect will be rolled out in stages, the first of which will focus on plasma exchange referrals. This approach will allow us to review and refine the system with feedback from patients and clinicians before moving to the next stage.
