Abstract
The present invention relates to novel methods and devices for differentiating in a patient parathyroid diseases, such as hyperparathyroidism and related bone diseases, from normal or non-disease states. One detects whole or non-fragmented (1 to 84) parathyroid hormone in a biological sample and also a large non-whole parathyroid hormone peptide fragment that can function as a parathyroid hormone antagonist. By either comparing values or using independently the value of either the large non-whole parathyroid hormone peptide fragment, the whole parathyroid hormone, or the combination of these values one is able to differentiate parathyroid and bone related disease states, as well as differentiate such states from normal states In specific embodiments, the present invention relates to isolated antibodies, including polyclonal antibodies, that specifically bind to a three-dimensional epitope of a parathyroid hormone (PTH) in PTH1-8 as part of whole PTH, wherein at least four amino acids in PTH1-8 are part of the reactive portion of the isolated antibodies, and the isolated antibodies do not specifically bind to a non-(1-84) PTH fragment, e.g., a PTH7-84 fragment.
