The lung function unit provides lung function (breathing) testing to patients from across England but mainly from the south east of England. We have two lung function laboratories, one based at Guy’s and the other at St Thomas’. We offer a variety of lung function tests (including exercise testing) to patients who have been referred for breathing problems.

We support a number of clinics such as Asthma, ILD and COPD and are experienced at testing patients with a wide variety of conditions.
