Vitamin B12 Blood Level
 

My symptom from my original post is here

http://neurotalk.psychcentral.com/thread165327.html

back in October 20120, I have the following test

Vitamin B12
==============
1277 pg/mL
Flag: H
Range: 245-894

also

Folate
=============
>20.0 ng/mL
Range > 7.2

At that time, I don't remember if I was taking any b12 vitamin or not. I used to take the sublangual b12,

The doctor simply told me at that time to stop taking vitamin.

there are so much info about what can cause b12 level to be high in the blood,

can someone provide additional information about that

when I do my next test, I will include b12

I also want to know if my symptom can be a part of b12 elevation in the blood

Elevated B12 does not cause anything that has been reported as yet.

However, in a person who is NOT taking vitamins, or eating enriched foods, having a high B12 level (over 900) can be a signal of some disease states. B12 does not cause these, but happens to be a result. And this is pretty rare.

A test result over 1000 when one is taking supplements of B12 is not a reason to stop taking it.

Some cancers, kidney disease, and excessive bacteria in the bowel may raise B12 levels.

If you were taking vitamins containing folic acid and B12 when that test was taken, your levels will reflect that, however.

Doctors don't understand B12, and because the results are flagged at the lab, they respond as if it were any old other flag that signals harm. They are creatures of habit, in other words.

What your doctor should say is this: "I see your B12 levels are high. Do you take supplements/vitamins? If the answer is NO, then we need to further test you to see why this level is high."

Some people need more B12 than others. The folate is a whole other story. In people who cannot methylate folic acid to methylfolate which is the active form, folic acid levels may test artificially high. It might mean you have a DNA error of metabolism called the MTHFR polymorphism, and that should be tested for then. Foods in US are now fortified with folic acid (which is synthetic and not natural), so if you consume them your folic acid level may show high. This is controversial at this time, since the food fortification is rather new.

Thank you for your input, when I do the next test, I will put the result here
