please see response on this post

your blood work is characteristic of microcytosis - consistent with iron deficiency

your folate is below range and your B12 is on the low side

if you have a history of B12 levels that shows a downward trend then that would be the clincher in relation to an absorption problem specifically relating to B12.

Are these results from a private blood test? If so suggest that you share with your GP along with details from the above post

Thanks very much for this information. B12 has been low more often than high but on occasion has shot up despite not supplementing or change in diet. The results are from an NHS blood test and GP is deciding not to take action on below range folate. I will go back to GP on Tuesday and insist they do something.


Also positive for intrinsic factor antibodies? Does that mean GP should be doing something about this? Thanks again.


if you have a positive for IFA and you weren't supplementing then that means that you have PA in the sense of an autoimmune response that is attacking the mechanism that allows you to absorb B12 - it can also lead to reduced stomach activity which will affect your ability to absorb other vitamins and minerals.

Your GP should definitely be treating you with loading shots (using the more aggressive regime for neurological involvement*) and then on to loading shots every 2 months - though no guarantee that that would be enough as a maintenance regime.

* 3xweekly until symptoms stop improving - review at 3 weeks.

the other issue would be around the timescales on the symptoms - if they came on quickly that would point to the folate deficiency - if they have developed slowly then that would point to B12 - the overlap with thyroid does make it all very difficult to evaluate what symptoms are caused by what though - so think approach to take with GP is getting them to a) look at absorption problems and b) be open to the idea that there is more than thyroid going on.

When you say shot up - how much? another thing to check is that the same units have been used each time as test results can be expressed in two different units - ng/L and pmol/L - though the results above are from measures that would produce the higher figures.


All levels came back in pg/L.

Just wondering, can/does the auto-immune process fluctuate, thus causing a change in B12 levels? I'm asking coz I don't have a clue but it could potentially be why results are up, then down, then up again etc??? ;)


I believe there are a few conditions (eg liver and kidney problems) that can cause the liver to dump the B12 that it is storing, resulting in raised B12 levels - but think the implication is that these would normally raise levels above the top of the normal range.

LizzieJ8 Prior to Feb last year it looks as if the levels were quite stable then they shot up in August 2016 and have been falling ever since. The drop is quite significant and would support an absorption problem - and IFA being positive would suggest that was PA.

The PAS has a microsite aimed at medical professionals - you could suggest to your GP that they take a look at it if they want to understand more about B12.
