Bio-intact PTH was measured by (a) a chemiluminescence immunoassay on the Nichols Advantage[R] platform (Nichols Institute Diagnostics) (2); (b) an IRMA using the Duo PTH reagents (Scantibodies Laboratory) (1); and (c) an ELISA using the Human BioActive Intact PTH reagents (Immutopics), which is a 2-site assay in which 2 goat polyclonal antibodies recognize epitopes within the midregion/carboxy terminus and at the initial amino terminus.
