Oscillometry is a test that uses sound waves to measure the mechanical properties in the lungs during tidal breathing

We will be optimising and evaluating the sensitivity and specificity of a novel breath volatile organic compound test of a combination of reactive aldehydes using a gas chromatography-ion mobility spectrometry device

We will be evaluating the sensitivity and specificity of a novel nasal swab test for eosinophil peroxidase

We will be evaluating handheld capnometry (carbon dioxide breath testing) to diagnose adult asthma
