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 blood test measuring IgG antibodies to Candida species, used to look for evidence of past or current systemic Candida infection.
1 biomarker as listed by Blue Horizon Medicals.
This test looks for IgG antibodies to Candida species, which, if present, show that your immune system has encountered the fungus at some point rather than confirming an active infection today. As the provider notes, a positive initial screen is followed by a further confirmatory test, the cost of which is included in the price.
As a single-marker test it sits around the middle of the immunity tests we track for depth. It scores less well on price, coming in above the median for similarly sized immunity tests we track, and on collection convenience, since it needs a venous draw at a clinic or nurse visit with no at-home option, and results take around 10 days, longer than most of Blue Horizon's other tests. On the plus side, the listing is clear, setting out a short description, the biomarker, sample type, turnaround and collection options.
Blue Horizon Medicals has traded since 2009 and uses UKAS ISO 15189 partner labs, with a Trustpilot score of 4.2 from 395 reviews. Results are reviewed by a doctor.
This may be worth considering if a clinician suspects systemic Candida involvement in your symptoms and wants an antibody-based starting point, bearing in mind the built-in confirmatory step if the first result is positive. Given the price and the longer wait, it is worth checking with a GP first whether this is the right test for your situation. We do not have peer tests logged in this comparison group, so we cannot point to a specific cheaper or faster alternative from another provider.
A healthcare professional takes a venous blood sample at a clinic or during a home nurse visit; there is no at-home option for this test. The lab tests for IgG antibodies to Candida species, running a further confirmatory test at no extra cost if the initial screen is positive, and a doctor reviews the result before it is released to you, typically within around 10 days.
Candida species IgG antibodies are what this test screens for, with a confirmatory test built into the £180.25 price if the initial result is positive. That price is above the median for similarly sized immunity tests we track, and the turnaround, around 10 days, is one of the longer ones in the range. There is no at-home collection option.
