Checks for intrinsic factor antibodies, commonly assessed when vitamin B12 levels are low. Suited to anyone whose B12 results suggest an autoimmune cause needs investigating.
1 biomarker as listed by Blue Horizon Medicals.
This test checks for intrinsic factor antibodies, which are commonly assessed when vitamin B12 is thought or known to be low. Absorption of vitamin B12 from the gut depends on intrinsic factor, so antibodies that inactivate it are a common cause of B12 deficiency, and can be linked to pernicious anaemia. The provider notes this test is often ordered alongside a gastric parietal cell antibodies test.
Against the 73 similarly sized vitamins and minerals tests we track, this single-marker profile sits in the 31st percentile for clinical depth, and its £101.25 price is around 19% above the £85.00 median for that group. Collection is by venous blood draw, at a clinic or via a home nurse visit, with results typically back within 5 days.
The score is held back mainly by a below-average clinical depth mark, reflecting the single-biomarker scope, and a value-for-money score that reflects the above-median price for this group. Results and follow-up score reasonably because a doctor reviews the results. Blue Horizon Medicals holds a 4.2 Trustpilot rating from 395 reviews, uses UKAS ISO 15189 partner labs, and has traded since 2009.
This suits anyone who has already been advised to check for intrinsic factor antibodies, typically alongside investigating a low vitamin B12 result, rather than as a first-line or standalone test.
Because it is a single-marker test priced around 19% above the median for similarly sized vitamins and minerals tests we track, it is worth checking with a GP whether this specific antibody check is needed before ordering, rather than a broader vitamins panel.
This is a blood test collected by venous draw, either at a clinic or through a nurse home visit; there is no at-home finger-prick option. Results are typically available within 5 days, and a doctor reviews them before they reach you.
This single-marker test checks for intrinsic factor antibodies for £101.25, with a doctor reviewing your results within 5 days. It is priced around 19% above the £85.00 median for the 73 similarly sized vitamins and minerals tests we track. It is a narrow, targeted test rather than a broad panel, commonly ordered alongside B12 testing rather than on its own.
