病毒性肝炎病情严重程度的计算机判别诊断-常用肝功能指标逐步判别分析

目的：常用肝功能指标模型诊断探索。方法：肝功能指标在临床现病情诊断中是非常重要的。以往人们多是从临床医学角度来判断，本文用统计学方法，对１０个常用肝功能指标ＴＰ（总蛋白）ＡＬＴ（总蛋白）ＡＬＧ（白蛋白）ＧＬＢ（球蛋白）Ａ／Ｇ（白／球）ＴＢＩＬ（总胆红素）ＤＢＩＬ（直接胆红素）ＩＢＩＬ（间接胆红素）ＡＳＴ（谷草转氨酶）ＡＬＴ（谷丙转氨酶）ＡＳＴ／ＡＬＴ（谷草／谷丙）进行了判别分析研究。结果：发现由Ｔ

Computer discrimination and diagnosis about the severity of illness of virus hepatitis-stepwise discriminant analysis of conventional items of liver function test

Objective:To study diagnosis of the model formed by conventional items of liver function test. Methods:The items of liver function test are very important in diagnosing patients condition of liver disease in clinic. In the past, doctors were used to observe the items only from medical aspect. This article, using the statistic method, studies ten conventional liver function test items including TP ALB GLB A/G TBIL DBIL IBIL AST ALT AST/ALT by stepwise discriminant analysis.Results:The discriminant model formed by six items(TBIL DBIL ALB ALT AST/ALT TP) can discriminate the severity of illness including slight, moderate or severe with accurate rate of 90% or above. Conclusion:The diagnostic effects of the model is satisfactory.
