How to refer a patient

This page explains how to refer a patient for a TAS treatment.

Coming soon - TAS Connect

The new TAS digital referral system will go live at the end of 2025, starting with plasma exchange, which will help to streamline our referral process.

Keep an eye out for updates here, and email updates.
