稳定同位素技术是一种应用钙稳定同位素来研究待测钙源在体内代谢情况的方法。该法具有安全、准确、操作简便等特点,尤其适于儿童青少年、孕妇和乳母的钙代谢研究。目前,该技术已成为测定钙吸收率的最佳选择。此外,在钙需要量研究和钙代谢动力学研究等领域,该技术的应用也逐渐增多。不过,昂贵的价格和复杂的检测方法始终是制约该技术广泛应用的主要因素。 Stable isotope technique is a method of using calcium stable isotopes to study the in vivo metabolism of calcium sources to be tested. The method is safe, accurate, easy to operate and other characteristics, especially suitable for children and adolescents, pregnant women and lactating calcium metabolism studies. At present, this technique has become the best choice for determining calcium absorption. In addition, the application of this technology is gradually increasing in the areas of calcium requirement research and calcium metabolism kinetics. However, expensive price and complicated detection methods are always the main factors restricting the wide application of this technology.
