Abstract
Improved competitive binding serum folate assay in which serum folate bound by folate-selective protein is separated from free serum folate by removal with an anion exchanger, preferably intermediate base anion exchange resin. Preferable are resins characterized by having an aliphatic lattice, particularly, a polyalkyleneamine lattice having tertiary and quaternary amine groups. The resin is advantageously added for the separation function in tablet form.
