Witryna22 lis 2011 · Parathyroid hormone (PTH) assays have evolved continuously for the last 50 years. Since the first radioimmunoassay was described in 1963, several assays based on immunological identification have been published (first generation assays).

Witryna1 kwi 2024 · The cross-reactivity of second generation PTH assays with non-(1-84) PTH have been shown using the 7–84 fragment as a surrogate, but it seems that this fragment is not present in humans [40], which can question the robustness of these models. Studies using high resolution mass spectrometers will certainly allow for a good …
