The effect of diphenylhydantoin on the microbial assay of serum folate.
1. Two modifications fo the usual method of assay for folic acid in solutions are reported which appear to improve this procedure. These are a reduction of incubation time and dilution with 95% ethanol. 2. Experimental results are reported which indicate that Dilantin (5,5-diphenylhydantoin) does not interfere with the microbiological assay for folic acid.
