000 pg/ml. The level declines throughout human life. Below 550 to 600 pg/ml, deficiencies start to appear in the cerebrospinal fluid. But, US clinical laboratories regard 200 pg/ml as the lower range of normal.
These cases underscore the need for a high level of clinical suspicion in elderly patients, also in cases of normal B12 levels but with clinical signs of deficiency and a positive risk factor, such as stomach or small bowel surgery or positive family history. Plain language title: A case ...

What is the Vitamin B12 normal range? Here are the reference levels: 210-910 pg/ml How do I get the report? It will be emailed to you by the diagnostic centre. However, if you requested and paid for the hardcopy, then it will be couriered to you too once the reports are done. Do...
Scientific testing over a long period showed “functional deficiency,” that is, an insufficient distribution of B12 at the cellular level, could come about even though serum levels were normal. NOW Methyl-B12 1000 mcg Sadly, the American medical community sees fit to keep the “normal” range...

it is likely not a concern. the intermediate range has become more difficult to interpret. a new understanding that a level of vitamin b12 in the lower end of the normal range could be associated with symptoms means that we now have something called subclinical vitamin b12 deficiency. in these...

The serum vitamin B-12 level is 205 pg per milliliter (151.2 pmol per liter), which is above the lower end of the laboratory reference range. The hemato-crit is 42%, with a mean corpuscular volume of 96 fl. The serum methylmalonic acid level is 3600 nmol per liter (normal level, <...
The serum concentration of vitamin B12 in this population of outpatients with severe SUD was predominantly within normal range, whereas only 1.2% have clear deficient vitamin B12 levels (<175 pmol/L). A fifth had levels that might have been suboptimal with vitamin B12 level < 300 pmol/L). ...
