Abstract A comparison of microbiologic assays for vitamin B12 in whole blood or serum was carried out with four B12-requiring microorganisms, Escherichia coli 113-3, Lactobacillus leichmannii ATCC No. 7839, Euglena gracilis, strain Z, and Ochromonas malhamensis. B12 values in whole blood and serum for normal subjects are given. The value of microbiologic assays is discussed.
