Immune System Blood Test
Highly rated for depth and priced well below the market
An 8-marker blood test covering white and red blood cells, vitamin D, B12, iron status and inflammation, for a broad check of immune-related health.
A swab test screening for 22 respiratory viruses and bacteria, for anyone with cold, cough or flu symptoms who wants to know the specific cause.
22 biomarkers as listed by Randox Health.
This test screens a swab sample for 22 respiratory pathogens, including influenza A and B, several coronaviruses, and bacteria such as Mycoplasma pneumoniae. Identifying the specific pathogen behind cold, cough or flu symptoms is commonly used to help guide the right treatment, rather than to diagnose a condition on its own.
With 22 biomarkers, it has the most clinical depth of any immunity test we track. There are no named peer tests in our data for this exact combination, so the value-for-money score reflects the lack of comparable pricing data rather than a specific judgement on £84 as a price.
Collection convenience scores reasonably well thanks to a fast 2-day turnaround, even though it requires a swab sample taken at a clinic rather than at home. It scores lower on results and follow-up, as it is not doctor-reviewed as standard, and its listing gives a shorter description than some other Randox tests.
This suits anyone with cold, cough or flu symptoms who wants to know the specific virus or bacteria involved, for example to understand whether antibiotics might be relevant. We do not have comparable named tests in our data to say whether a cheaper or broader alternative exists. If your symptoms are severe or you are in a vulnerable group, contact your GP rather than relying on this test alone.
You provide a swab sample at a Randox clinic. The lab screens it for 22 respiratory pathogens, with results available within 2 days of the sample arriving. The provider does not state that a doctor reviews the results as standard.
