当机体处于疾病状态时，血浆中纤维蛋白原和球蛋白浓度增加，红细胞聚集性增强，血液流动性减弱，导致组织或器官缺血、缺氧。红细胞聚集指数是由低切黏度比高切黏度计算而来，它反映红细胞聚集性程度的客观指标，增高表示聚集性增强。
结果显示：全血粘度、血浆粘度及红细胞聚集指数均明显增高。
The results showed that the whole blood viscosity, plasma viscosity, and aggregation of erythrocytes increased significantly.
运用逐步回归分析法得出了影响乌鳢全血粘度的主要因子为红细胞压积和红细胞聚集指数。
By means of regression analysis, it was shown that the common factors which affected whole blood viscosity of Ophicephalus Argus were hematocrit and erythrocyte aggregation index.
而膳食控制后2型糖尿病大鼠红细胞聚集指数显著降低，其他指标都有所改善，但无显著性差异。
After the dietary control in type 2 diabetes, the erythrocyte aggregation index decreased significantly, other indicators had some improvement, but there were no significant difference.
