Comparison of the radioisotope dilution-coated charcoal method and a microbiological method (L. leichmannii) for measuring vitamin B12 in serum.

J L Raven, P L Walker, P Barkhan.   

Abstract

A comparison has been made of the radioisotope dilution-coated charcoal method and a microbiological assay (with L. leichmannii as test organism) for determining the concentration of vitamin B(12) in serum. A satisfactory correlation was found between the results of the two methods. Under appropriate conditions the reproducibility of the radioisotope method compared favourably with that of the microbiological method.
