Please can I have some advice? Google is making things worse!

I've recently been having some really unpleasant symptoms, extreme tiredness, vertigo and joint pain to name a few. I was referred to my local hospital neurology department for further investigations, and subsequently I had an MRI scan done, I'm currently waiting for those results. They took bloods at the hospital, revealing my B12 to be 157ng/L. My GP surgery followed up with a blood test looking for the intrinsic factor antibody which was negative, so no further action needed. I should mention that both my mother and brother have pernicious anaemia.

Anyway the thing is, I was looking through my medical file and I saw the results of some bloods I had done in 2013, these were to investigate an ongoing stomach condition, which has since been diagnosed as bile acid malabsorption. At the time I was told that my vitamin D was low, but it seems that two of my other tests were outside the guidelines. Serum Parathyroid hormone was 10.2pmol/L and IgA 3.92g/L, both higher than normal, yet no one has ever mentioned these results to me? Perhaps they were overlooked? The thing is, I think I should Should flag this up with my GP but is it likely these results could have any bearing on my current condition? or could they have since resolved themselves?

High levels of parathyroid hormone can have many causes. Luckily the least nasty is, in your case, the most likely - low Vit. D.

According to this - - your IgA is within range.

The worrying thing is that you're not being treated for your pernicious anaemia. Yes, you did test negative for the IFABs, but so do 50% of people with PA. The fact that you have a family history of PA, that you have symptoms of PA and that you have low levels of B12 all point to a strong likelihood of PA. So go back to the GP and demand proper treatment for PA and vitamin D deficiency.


Thank you fbirder! I saw the Southtees post you kindly linked. It was my surgery that red lined both results, and in this case it recommended a level of 0.8-3g/L for the IgA, with Southshields at 0.9-4.5g/L, but three years on it could of course be very different!


My IgA was also high sometime last year - just a little bit, about the same level as yours IIRC. Doc said it often does increase with some autoimmune problems.
