Pulmonary Function Test

Express Diagnostics pulmonary function tests are those of spirometry to assess pulmonary mechanics. The test includes forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and forced expiratory flow (FEF).

Measuring pulmonary mechanics assesses the ability of the lungs to move large volumes of air quickly through the airways to identify airway obstruction. The measurements taken by the spirometry device are used to generate a pneumotachograph that can help assess lung conditions such as: asthma, pulmonary fibrosis, cystic fibrosis, and chronic obstructive pulmonary disease (COPD).

Further to this, we offer reversibility testing where comparison is made between initial readings and readings taken a short time after inhaling a short acting bronchodilator. Reversibility testing is useful in differentiating between classical presentations of asthma (often fully reversible airway obstruction) and COPD (not fully reversible or irreversible airway obstruction).
