High Levels Of B12

Posted by cocoa @annieecruz, Apr 29, 2018

What type of doctor handles test like the MMA Urine test and the HoloTC? Test related to how your body breaks down/absorbs and transport/bonds B12? My B12 test came back extremely abnormal.

@sakota ..Yes, tested twice ..both results were >2000..all of the other blood testing results have been within the normal range, except for my B12. The testing started because my neurologists was looking for a possible underlying cause for my autonomic peripheral neuropathy diagnosis, and a low B12 could be a cause…however with the high test result, I am now being referred to an oncologist….I think and hope its just an anomaly

Are you taking a multivitamin? I too have had high vitamin B on my labs for the last 2 years during periods of time where I stopped my multi vitamin. I have found the most vitamins have well over the recommended daily allowance of B vitamins. I have had two instances a couple of years appart where I was taking a multivitamin (one had 400% and the other 800% of the daily allowance) and I had to stop taking them because my blood pressure was high, ringing in my ears, I was having trouble sleeping, and I was anxious. I have just asked my Dr. to repeat the test again. I think if it is high again, I will need to find answers if B can store in your body for long periods of time.

Welcome to Connect, @marlenerose33.

Along with some more information on the significance of b12 levels, https://medlineplus.gov/ency/article/003705.htm I found this recent study that I thought might interest you:
"An observational study of vitamin b12 levels and peripheral neuropathy profile in patients of diabetes mellitus on metformin therapy” https://www.sciencedirect.com/science/article/abs/pii/S1871402117302874

With regard to neuropathy, very often there is no identifiable cause – there are a number of conditions that can trigger it. May I ask if you noticed anything that might have triggered the neuropathy?

Hi, my dad’s B12 test results came very high.

Basically his B12 level is >2000 when the normal range is 200-900.

Is it normal? Should we worry about it? Any other tests that we need to check.

With his current chemo Pemetrexed , the doctor told to take B12 shots 7 days before the chemo with folic acid and he did it during last chemo. His another cycle is coming in one week and I guess we should stop B12 but very confused now since there are many discussion on that. Thanks

I am new to this board and not entirely sure how to post but here I go, In October of 2018 I had an appointment with my family medicine doctor regarding some mild neurological symptoms I was having (pins and needles, burning skin, and the feeling, in specific areas, of a bug crawling). I have had fibromyalgia for over 20 years and she basically said that everyone has my symptoms but that I notice it more due to the fibro. I was not a fan of that answer primarily because she has made other comments about fibro that have led me to think she is not a believer. She offered to do a Vitamin B12 test to see if I was deficient. My test results came back with a vitamin B12 level of 1,726 pg/mL which she seemed unconcerned about. I went back this week for an annual check up and I asked her to redo the Vitamin B12 test which she did and my results came back as >1999 mg/mL. I spoke with her nurse who told me that I could come in to talk about the results but that they did not have much to offer me. She also told me that my CBC was normal. There has to be a reason that my B12 is going up, I do not take any supplements. And everything I read about high B12 is not good. But since my CBC came back normal should I just assume all is well?

I too have had two B12 labs done. One in the 1800s and one 1700s. I am interested in anyone’s experience with this.
Thank you.

I forgot to mention that I normally have low Red blood platelet count. Which if I use any form of pain medication depletes it almost completely. I've had Tests done for my Liver so it's not that. But I have asked about possible VIII as it runs in our family.I have a life long history of anemia .

I think you need to ask your doctor about this. Maybe ask them to redo the test. I see my doctor Monday and I am going in with medical articles that talk about high B12 and what could be causing it. In addition to what might be causing it, I have read that high B12 is functionally low B12 because it means your body is not utilizing and it is also not being eliminated.

My primary care doctor told me to just forget about my B12 levels and when I insisted we do further research, she asked me who i thought she should refer me to. I told her I didn't know so she referred me to a local hematologist who declined the referral. My inclination is to look for another specialist maybe at UCSF medical center. What are others experiences of this kind of situation?
