Simultaneous assay for vitamin B12 and folate compared with separate assay.
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.
