Should one worry about an increases vitamin B12 level?

Question

Hello doctor,

I had pain in my right lower back following playing basketball. I consulted a physiotherapist, and he suggested me do some blood work for inflammatory markers, and the results were normal. I also did complete blood count (CBC), liver function test (LFT), kidney function, cholesterol, CRP, blood glucose, iron studies, vitamin D, thyroid function test (TSH, T3, T4), and vitamin B12.

Everything was normal, except vitamin B12 level, which came back as > 1476 pg/mL. I do not take B12 supplements. Should I be worried about this reading?

Kindly give your opinion.

Answer 1

Hello,

Welcome to icliniq.com.

Elevated vitamin B12 levels can be seen in certain blood-related conditions like myeloproliferative disorders. It may also be seen in some liver conditions. Since all the remaining values are normal, these conditions seem unlikely in your case. However, to be sure, you can repeat the tests in another six to eight weeks.

Regards.

Answer 2

Hello,

Welcome back to icliniq.com.

It is quite a common scenario that we come across. The supplements you consume can have added vitamins that can lead to high readings. I suggest you avoid vitamin supplements or power drinks for a few days until you repeat the test. The pain you have in your feet and sole could be because of increased physical activity. I do not think that it is because of high vitamin B12.

Take care.
