Diagnostic demand and capacity modelling estimates that 35% of the capacity required between 2026/27 and 2028/29 needs to come from the IS. This equates to an estimated additional 2 million tests and could be achieved through either capacity or productivity initiatives, including digital infrastructure and tools.
