Investigating factors that contribute to bone loss and accretion across populations in remote settings is challenging, particularly where diagnostic tools are scarce. To mitigate this challenge, we describe validation of a commercial ELISA assay to measure osteocalcin, a biomarker of bone formation, from dried blood spots (DBS).

酶联免疫测定法对干血斑中骨形成的标志物骨钙素的验证。

在偏远地区，尤其是在缺乏诊断工具的地方，调查导致人群骨质丢失和增生的因素具有挑战性。为了缓解这一挑战，我们描述了一种商用ELISA测定法的验证，该测定法可从干血斑（DBS）中测量骨钙蛋白（一种骨形成的生物标志物）。
