GP B12 Serum - 'normal' at 289

[Hello1986]

Hello everyone.

I have just received results of my blood tests. I was being tested for B12 because I am having tingling in my hands and feet - sometimes this can actually be quite sharp, like I'm being used as a pin cushion.

When I rang today the Receptionist said 'normal' and when I asked for the number she said 289. Looking online the ranges seem to differ so much depending on the lab!

My question is, has anyone had this result (or around this) and had symptoms? They have literally just tested serum B12, so I understand this doesn't reflect active levels?

A bit of background history should this help - I've had a diet change quite recently as I'm suffering with candida badly. I've cut out a lot of things, including bread.

Thank you in advance!

We really need the units (pmol or ng) along with the range. However, most assays will have 289 somewhere close to the average.

The tingling might still be caused by a B12 deficiency. Or it could be due to one of the other 80-odd possible causes. You really need a referral to a neurologist.

Thanks. I will find out more when I see the GP on Thursday. This was a quick call with a receptionist who was confused as to why I wanted the actual number.

I may supplement and see if symptoms improve although need to ask the GP about that as I'm not sure whether other supplements (if any) may be required to ensure absorption and the like....

My B12 has been consistently under 300 for the last 2 years (I suspect further, but I can't yet access online and have had to request copies manually). My last results were: 190ng/L, 281, 230 and 268 (with a range of 187-883). I have been complaining of ongoing symptoms (which are gradually worsening) for about 4 years. My GP has flat out refused to treat insinuating the low figures are my doing due to poor diet (my diet and exercise regime is very good). Im currently being tested for pernicous anemia.

Thank you for this. I'm wondering if I've ever been tested before to see what my own 'baseline' would be as the ranges seem to vary considerably!

[ILR2019 in reply to Hello1986]

The first piece of advice I can give is ALWAYS obtain a copy of test results and NEVER accept the term 'normal'. Normal really doesn't mean anything as normal to you, me and everyone else differs.

From my own experience my surgery would rather have me book an appointment every month at an average cost of £40 each visit and leave me symptomatic and potentially costing the NHS more money long term than cheaply treat me and allow me some normality (particularly when other countries have a much higher threshold).

It could be many things. But it could be B12 as well. Please read stichtingb12tekort.nl/weten... and perhaps get an MMA test to be sure.
