由于世界上广泛的存在着蛋白质及蛋白热量的不足以及在其他疾病时,作为继发性症状表现出来的蛋白质不足,就决定了除解决其他问题之外必须制定一种可靠的诊断方法,特别是初期及轻形的蛋白质不足的诊断方法。目前已提出大量的评价人体蛋白质不足的诊断手段。但是其中大部份或是不敏感、或是不具特殊性。在这方面主要对两种生化方法寄于了较大的希望:血浆中氨基酸的相互关系及肌酐酸系数。随着氨基酸测定方法自动化的出现,使有了用严格标准技术条件对研究结果进行客观 Due to the widespread presence of protein and protein calorie deficiencies in the world and the lack of protein as a secondary symptom in other diseases, it has been decided that in addition to solving other problems it is necessary to develop a reliable diagnostic method, in particular Early and light-shaped protein deficiency diagnosis. A large number of diagnostic tools have been proposed to evaluate human protein deficiency. But most of them are either insensitive or peculiar. In this regard, two biochemical methods are mainly sent to the greater hope: the relationship between plasma amino acids and creatinine coefficient. With the advent of automated amino acid determination methods, there has been an objective assessment of the results using rigorous standard techniques
