Furthermore, this assay requires overnight incubation and may give false results if any inactive vitamin B₁₂ analogues are present in the foods. Currently, radioisotope dilution assay (RIDA) with labelled vitamin B₁₂ and hog IF (pigs) have been used to determine vitamin B₁₂ content in food. Previous reports have suggested that the RIDA method is able to detect higher concentrations of vitamin B₁₂ in foods compared to the microbiological assay method.
