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.
Screens for cytomegalovirus, rubella and toxoplasma antibodies, IgG and IgM for each. Aimed at women planning a pregnancy, or already pregnant, who want to check immunity to these infections.
6 biomarkers as listed by Medichecks.
This test checks IgG and IgM antibodies against three infections grouped under the TORCH acronym: cytomegalovirus, rubella and toxoplasma. IgG and IgM results are commonly used together to work out whether someone has past immunity, a current infection, or no exposure at all, which is relevant when planning a pregnancy or during pregnancy, when these infections can affect a developing baby.
There is no named comparison group for this test, so it cannot be benchmarked against specific rivals here. Against the wider set of similarly sized immunity tests Medichecks and other providers offer, its six markers place it in the 93rd percentile for depth, but its £269 price is more than double the roughly £130 median for tests of similar size.
This shows clearly in the scores: it does very well for clinical depth given the breadth of markers, but scores poorly for value for money because of the price gap. Collection convenience is limited to a venous draw at a clinic or a home nurse visit, since there is no finger-prick option, and results take around 5 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 is aimed at women who are pregnant, trying to conceive, or who want to check their immunity status to cytomegalovirus, rubella and toxoplasma before or during pregnancy.
Given the price, it is worth confirming with your GP or midwife what antenatal screening you are already entitled to before paying for this privately. There is no named comparison group for this test, so we cannot point to a specific cheaper rival here; Medichecks does offer a standalone Toxoplasma Antibodies test for £99, though that covers only one of the three infections in this panel.
This test needs a venous blood draw, either at a Medichecks clinic or through a home nurse visit; there is no finger-prick option. The lab tests the sample for IgG and IgM antibodies to cytomegalovirus, rubella and toxoplasma, and a doctor reviews the results before you receive them. Medichecks states a turnaround of around 5 days.
This six-marker panel checks IgG and IgM antibodies to cytomegalovirus, rubella and toxoplasma, at £269. That is well above the roughly £130 median for similarly sized immunity tests we track, and it requires a venous blood draw at a clinic or nurse visit rather than a finger-prick, with results in around 5 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.
6 biomarkers, placing it in the 93rd 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.
Trustpilot 4.5 from 2,477 reviews; accredited lab (UKAS ISO 15189 partner labs); doctor review as standard; trading 25+ years.
£269.00 against a median of £130.25 for the 17 similarly sized immunity tests we track (+107%).
