title: Simultaneous assay for vitamin B12 and folate compared with separate assay.
abstract: Radioligand methods are now well established for measurement of serum vitamin B12 and folate. Often these two assays are requested together. Thus a way of doing them simultaneously would save considerable time and expense. The objectives of this study were to determine the precision of a simultaneous assay and to compare it with previously established assays for these vitamins.
