Nearly 2 years ago I had a blood test privately as a result of investigation into a lump in my neck (which is fine). The blood test indicated borderline B12 levels so the Doctor recommended my GP retest in 6 months. I’ve only just got round to doing so - I’m in the UK.
They assure me this latest test was normal so I asked for a print out . The test says it was a full blood count but I cannot see anywhere where it says B12. Would anyone be so kind to explain these results to me? Is this the correct blood test to check B12? Thank you.

This is a full blood count. It would show if you had megaloblastic anaemia, which is one possible outcome of a B12 deficiency. But it’s not a definitive test.
Thank you. It annoys me that I was referred to the phlebotomist for a B12 blood test and this is what they did! I have booked a telephone appointment for Friday to discuss this. I also want my thyroid checked as my symptoms are more indicative for that under active thyroid as I think. I don’t know if they will do any of this though. Can they refuse?
Depends on the GP...yes they can refuse...but they didn’t ought too if you have symptoms that could be due to hypothyroid.
If they agree, the main issue is that GPs usually only test TSH, which does not give true thyroid status. What's really needed is a full thyroid panel consisting of TSH, FT3, FT4, and the thyroid antibodies TPO and Tg (antibodies important too because one of the main cause of hypothyroidism is autoimmune Hashimoto's - and this is only picked up by measuring thyroid antibodies.
Many on the thyroid forum resort to private testing to get the full thyroid panel done. If you want more information about this or thyroid issues in general, here's a link to the thyroid forum:
