per ml. any assay procedure should separate this range of vitamn B12 levels into easily recognized diagnostic groups. The quantity of co57b12 used in the radiodilution method determines its sensitivity within a particular range. To meet these requirements 500 pg. co57b12 is used in the method...
Vitamin B12 measurement was done at the biochemistry laboratory of Selcuk University Meram Medical Faculty with the original Beckman kits (Beckman Coulter, California-USA) by chemiluminesans method. Results The reference levels obtained for vitamin B12 at P2.5-P97.5 range were; 127–606 pg/ml...
reference values may vary markedly among populations and cultures. One reason for this is that diet varies significantly. The laboratories of any particular country are expected to investigate values in relation to their population. But, the reference range seldom reflects healthy vitamin B12 levels. ...

Vitamin B12 concentration was determined by radioassay in 179 healthy volunteers between the ages of 20 and 93 years in order to determine whether vitamin B12 levels decline with advancing age. The authors found no statistically significant decline in vitamin B12 levels in older individuals, nor a ...
The aim of this study is to determine the vitamin B12 levels in adults living in three villages in the Canakkale region, western part of Turkey. Some study result show that concentration of Al in water around Kirazli region is extremely high.Therefore the neurotoxic effect of Al was investigate...
Vegetarians are more prone to vitamin B12 deficiency than non vegetarians.. Vitamin B12 intake and serum vitamin B12 levels were positively correlated..Maternal vitamin B12 deficiency or lack of intake, may be due to low vitamin B12 in the milk causing vitamin B12 deficiency in infants. (2) ...
There is debate over the reliability of non-animal sources of Vitamin B12. It was found that people on vegan diets had lower levels of serum B12 levels than the general population. In particular, infants breast-fed or fed a macrobiotic diet directly are at a great risk of developing B12 de...
