A rash appearing on the patch could allow early treatment to stop problems escalating.

Some people having a lung transplant on the NHS will receive a skin patch graft from their donor too as a way of spotting organ rejection sooner.

Rejection could show as a rash on the donated skin patch, say experts, allowing early treatment to stop problems escalating.

The trial, by University of Oxford and NHS Blood and Transplant, will enrol 152 patients in England.

It follows earlier success with some other transplant patients.
