Private Lung Function Test: Costs, Process & Booking Guide

What Is a Lung Function Test?
A lung function test (also called spirometry or pulmonary function testing) measures how well your lungs work. It checks:
- How much air you can breathe in and out
- How quickly you can exhale
- How well oxygen moves into your blood
These tests help diagnose and monitor conditions like asthma, COPD, pulmonary fibrosis, and other respiratory issues.

NHS vs Private Lung Function Testing
While the NHS provides lung function testing for free, you may face delays — especially for specialist tests like DLCO or body plethysmography. Private clinics can often see you within 24–72 hours, sometimes even same-day.
