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 for measles IgG antibodies, used as presumptive evidence of immunity when there is no sign of acute infection.
1 biomarker as listed by Blue Horizon Medicals.
This test looks for IgG antibodies to measles in your blood. Their presence is commonly treated as presumptive evidence of immunity, provided there are no clinical signs suggesting an acute infection at the time of testing; a negative or equivocal result may mean immunity cannot be confirmed.
As a single-marker test it sits a little below the middle for clinical depth, in the 36th percentile of the immunity and infection tests we track, since many other tests in that category cover several markers. On price it stands out: at £41.25 it costs around 71% less than the £144.25 median across the 79 similarly sized immunity tests we track. Blue Horizon does not list a directly comparable competitor test for us to name here.
The listing publishes a short description, the marker, sample type, collection options and turnaround, supporting a solid clarity score. Collection needs a venous draw at a clinic or a nurse home visit rather than an at-home kit, and results take around 3 days. Results are reviewed by a doctor, and Blue Horizon uses UKAS ISO 15189 partner labs, with a Trustpilot score of 4.2 from 395 reviews.
This suits someone who needs to provide evidence of measles immunity status, for example ahead of travel, a new job in healthcare or education, or pregnancy planning, where a GP or employer has asked for antibody evidence rather than vaccination records. It is not a general infection screen, so if you have symptoms of an acute illness you should see a GP rather than relying on this test alone.
You provide a venous blood sample at a clinic or via a nurse home visit; there is no at-home finger-prick option for this test. Results are typically available within around 3 days and are reviewed by a doctor before you receive them.
