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.
Measures tryptase, an enzyme released during allergic reactions or certain other conditions. Suited to investigating a possible allergic reaction or as directed by a clinician following a reaction.
1 biomarker as listed by Medichecks.
This test measures tryptase, an enzyme released into the blood alongside histamine during an allergic reaction, or in some other medical conditions. A raised level can be used to help investigate a suspected allergic reaction or certain other conditions your doctor may be looking into.
There is no named comparison group for this test, so it cannot be measured against specific rivals here. Against the wider set of similarly sized immunity tests Medichecks and other providers offer, its single marker places it in the 36th percentile for depth, a narrow, targeted test rather than a broad panel, and its £129 price sits around 11% below the roughly £144 median for tests of that size.
It scores modestly for clinical depth, reflecting the single-marker scope, and reasonably for value for money given the below-median price. Collection convenience is limited, since it needs a venous draw at a clinic or a home nurse visit, with results taking around 6 days. It scores well on trust signals, reflecting Medichecks' Trustpilot record and its UKAS ISO 15189 partner labs, and on results and follow-up because a doctor reviews the results.
This suits someone who has been advised to check their tryptase level specifically, for example after a suspected allergic reaction, rather than someone wanting a broad allergy screen. Because it measures only one marker, it is not a general allergy panel.
There is no named comparison group for this test, so we cannot point to a specific cheaper rival here. If you want a wider look at allergy or immune markers rather than tryptase alone, it is worth checking Medichecks' other immunity tests for a broader panel.
This test requires a venous blood draw, either at a Medichecks clinic or via a home nurse visit; there is no at-home finger-prick option. The lab measures tryptase in the sample, and a doctor reviews the result before you receive it. Medichecks states a turnaround of around 6 days.
This single-marker tryptase test costs £129, around 11% below the roughly £144 median for similarly sized immunity tests we track. It measures one enzyme rather than a panel, so it is a narrow, targeted test. It requires a venous blood draw, with results taking around 6 days.
The listing publishes a short description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
1 biomarkers, placing it in the 36th percentile of immunity tests we track.
A blood sample taken at home by a visiting nurse or phlebotomist; with a venous or clinic option as well; a home nurse visit is offered; results in around 6 days, slower than similar tests.
Results are reviewed by a doctor; the provider does not describe the report format.
Trustpilot 4.5 from 2,477 reviews; accredited lab (UKAS ISO 15189 partner labs); doctor review as standard; trading 25+ years.
