Yes, but...: ...It is a very nonspecific test, elevated whenever there is any inflammation present. The erythrocyte sedimentation rate (ESR) measures how "sticky" red blood cells are. Fibrinogen is a blood protein that increases in response to just about any inflammatory reaction in the body, causing rbcs to stick together. While the ESR could increase after a gb attack, it is too nonspecific to be useful.
