Background: Assays for parathyroid hormone (PTH) are not standardized and therefore method-specific reference intervals are necessary for interpretation of results. PTH increases with age in adults but age-specific reference intervals for the Abbott intact PTH (iPTH) assay are not available. It is challenging and resource intensive to derive age-specific reference intervals by direct method because, depending on number of age partitions, samples from a large n...
