About this test

The Lung Function Test uses spirometry to measure FEV1 and FEV6, the amount of air you can expel from your lungs over set time periods, plus an obstructive index that classifies any obstruction as standard, mild, moderate or severe. Bluecrest notes that if you smoke, you also receive a 'lung age' calculation comparing your actual age with an estimate based on your lung performance. These readings are used to help flag possible respiratory impairment, most commonly linked to COPD (chronic obstructive pulmonary disease).

With three readings, it places in the 21st percentile for clinical depth among the general health and wellness tests we track, reflecting that it's a quick physical measurement rather than a blood panel. On price, it stands out: at £40, it costs 63% less than the £109 median for the 21 similarly sized wellness tests in our data.

Clarity is only partial here: the listing gives a detailed description of what's measured, but Bluecrest does not state a turnaround time, the sample type, or what the results report looks like, which is reflected in a middling clarity score. As with most of Bluecrest's individual tests, there is no doctor review included as standard.

Who is it for?

This suits you if you want a quick, low-cost check on your breathing, particularly if you smoke or have a family history of lung conditions, since Bluecrest cites estimates that around 2 million people in the UK have an undiagnosed lung condition. It is a reasonable add-on to a wider health check rather than a full respiratory work-up. If you have persistent breathlessness, a chronic cough or other respiratory symptoms, see your GP rather than relying on this test alone.

How it works

This is an in-person spirometry measurement rather than a blood or stool sample, carried out at a local Bluecrest venue. Bluecrest does not state how long results take to come back or what the report looks like. There is no doctor review included as standard.
