Do I Have To Get Some Blood Tests Before Doing A B12 Test
No: A B12 test is a blood test, and is done at the same time. ...Read more
Trust the blood test: B12 deficiency mimics everything from syphilis to Alzheimer's. Trust the blood work. Don't try to self-diagnose. If you're a vegetarian, you MUST supplement. If you supplement or eat meat, and you're B12 deficient, you have problems absorbing it and will need to take injections for the rest of your life. ...Read more
Accurate: We pathologists are focused on labs. In testing for B12 deficiency, we're looking largely at the ability to absorb it, and perhaps at its absence in the diet (even modest vegetarians are prone to be low). A non-fasting serum B12 in the normal range would reassure me and i'd not ask for a repeat fasting. ...Read more
I have vit b12 on high end- 820. Last year was 900. I'm vegetarian, but eat lots of beans, dairy. Other blood tests normal. Ok that it's that high?
High but normal: You B12 levels are at the high end of normal, but these results are not abnormal and are not a cause for concern. For more info you may consult this stie: http://www.nlm.nih.gov/medlineplus/ency/article/003705.htm ...Read more
Does taking b12 a week before an intrinsic factor blood test cause a false reading? Would it affect a b12 test too?
Depends on the test: The test for intrinsic factor is usually antibody to intrinsic factor and that would not be affected. If the B12 test is measuring the blood level of the vitamin, then that would be affected and yield a higher reading than the baseline, without the B 12 supplement. ...Read moreSee 1 more doctor answer

Just received my blood tests back and it states that my B12 is >1500....what could be the cause and what could happen to me because of this?
Taking B12 or...: High B12 is harmless as it's not toxic; the most common cause is taking B12 & since you're taking it that's probably why it's high.. However, high B12 in someone who isn't taking it can be a sign of serious problems like liver or kidney disease or myelproliferative disorders. High B12 does not cause these but caused by them.

My neorologist gave me some blood tests and my b12 came back with the result of 1243 and Mma at 74. Should I be concerned with cancer? I've had thyca
You're fine: High B12 never means anything nowadays. There are a few uncommon, obvious diseases in which it tends to be high. I am going to assume your units on methylmalonic acid suggest a high value and that also means nothing. Reference ranges are set so that a few percent of healthies fall outside on either end. Be glad for good health. ...Read moreSee 1 more doctor answer
