At-home health test
Vitamin B12 Test
Vitamin B12 is needed to make red blood cells and to keep the nervous system working. Deficiency builds slowly and often reads as ordinary tiredness. It is more common on a vegetarian or vegan diet, after 60, and in people taking metformin or long-term acid-reducing medication. Your results are delivered to you directly by Randox. If you would like them explained, you can book an optional follow-up consultation with an IMC-registered Global Health doctor from €45.

Before you test
What to know before testing
Drink water beforehand
On the morning of collection, drink plenty of water. Being well hydrated improves circulation and makes it easier to collect a clean sample.
Recent supplements raise the reading
A result taken while supplementing reflects the supplement, not your baseline. If you want a true baseline, speak to a doctor about timing before stopping anything.
Questions
Frequently asked questions
Should I stop my B12 supplement first?
Recent supplements raise the reading, so a result taken while supplementing reflects the supplement rather than your baseline. If you want a baseline, discuss timing with a doctor before stopping anything.
Is this a finger-prick test?
No. The kit uses a QuickDraw collection device placed on your upper arm, so there is no finger-pricking. Step-by-step instructions are included.
How long do results take?
Randox reports results 2–3 working days after your sample arrives at the laboratory. Activate your kit and post it back the same day you collect the sample.
Is a doctor's review included?
No. The price covers the kit and its laboratory analysis, and your results come to you directly from Randox. A follow-up consultation with an IMC-registered Global Health doctor is booked separately, from €45.
