ABSTRACT:
A serum sample is heated at an alkaline pH to release folate and vitamin B.sub.12 from endogenous binders. A simultaneous radioassay for folate and vitamin B.sub.12 is effected by contacting the sample with binder for folate, binder for vitamin B.sub.12, folate labeled with one radioactive isotope and vitamin B.sub.12 labeled with another radioactive isotope, followed by separation of bound and free portions, and determination of the radioactivity of at least one of the portions. The amounts of folate and vitamin B.sub.12 present in the sample may be determined from standard curves.
