RBC成叠连状，称为“缗钱壮红细胞”，当血清蛋白质，特别是纤维蛋白原和球蛋白增加时出现。这样长的RBC链更容易沉积下来，这就是沉降率升高的机制，见于非特异性炎症时，急性期血清蛋白质增加。
The RBC's here have stacked together in long chains. This is known as "rouleaux formation" and it happens with increased serum proteins, particularly fibrinogen and globulins. Such long chains of RBC's sediment more readily. This is the mechanism for the sedimentation rate, which increases non-specifically with inflammation and increased "acute phase" serum proteins.
