Comparison of two radioisotope dilution assay kits for measuring vitamin B12 in gruel.
The results obtained using two commercially available radioisotope dilution (RID) assay kits for determining vitamin B12 were compared. Comparison of the results obtained with the two RID methods gave a correlation coefficient of 0.9390 for gruel samples. The results obtained with one of the kits were slightly lower, probably due to a difference in the RID assay techniques.
