  • Patent number: 6743590
    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.

  • Patent number: 6689566
    Abstract: The present invention relates to novel methods and devices for detecting whole or non-fragmented parathyroid hormone (wPTH) in a biological sample. In particular, a novel monoclonal or polyclonal antibody or antibody fragment is used that is specific for a portion of the initial peptide sequence for wPTH which comprises a domain for adenylate cyclase activation, (amino acids 2 to 8), wherein at least four amino acids in this sequence are part of the reactive portion with the antibody. The present wPTH assay can differentiate between the complete 1 to 84 amino acid sequence form of PTH and a large but incomplete 7 to 84 amino acid sequence form of PTH that is measured by commercially available “intact” or I-PTH assays. Measurement of both the complete biologically active form of PTH and the large but biologically inactive form of PTH can lead to the misdiagnosis of the parathyroid function in patients.
