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.
Checks Varicella Zoster (chickenpox/shingles) IgG antibodies, commonly used to check immunity status. Suited to a quick, specific immunity check rather than a broader infection or immunity panel.
1 biomarker as listed by Blue Horizon Medicals.
This test measures IgG antibodies to Varicella Zoster Virus (VZV), the virus responsible for chickenpox and shingles. A positive IgG result is commonly used as an indication of immunity, for example to check status before travel, pregnancy planning, or certain occupational requirements, though it doesn't diagnose active infection.
As a single-marker test, it sits below the average depth for the immunity tests we track, in the 36th percentile by marker count. Where it stands out is price: at £54.25 it's priced well below the £144.25 median for similarly sized immunity tests we track, a saving of around 62%.
It scores particularly well for value for money given that price gap, and reasonably for documentation and results and follow-up, since the biomarker, sample type, turnaround and collection options are published and a doctor reviews the result. It scores more modestly for collection convenience, since it needs a venous draw at a clinic or nurse visit rather than an at-home option, with results back in 5 days. Blue Horizon has traded since 2009, holds a Trustpilot score of 4.2 from 395 reviews, and uses UKAS ISO 15189 partner labs.
This suits anyone who specifically needs to check their Varicella Zoster (chickenpox/shingles) immunity status, such as ahead of travel, pregnancy planning or a workplace requirement, and wants a doctor-reviewed result at a price well below the typical cost for a single immunity marker.
It isn't the right choice if you want a wider check on your immune system, since it only covers this one antibody. If you have symptoms of shingles or chickenpox, see a GP rather than waiting for this test.
This is a venous blood test, taken at a Blue Horizon clinic or by a home nurse visit. The sample is tested for Varicella Zoster IgG antibodies, with results back in around 5 days. A doctor reviews the result before you receive it.
A single-marker Varicella Zoster IgG antibody test, priced at £54.25 and reviewed by a doctor. It's priced well below the £144.25 median for similarly sized immunity tests we track, a notable saving for a single-marker test. Since it only covers this one antibody, it won't tell you about immunity to anything else.
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 5 days, slower than similar tests.
Results are reviewed by a doctor; the provider does not describe the report format.
