A high erythrocyte electrophoresis index, which is a prolonged erythrocyte electrophoresis time, causes enhanced erythrocyte aggregation. This indicates increased aggregation of red blood cells and platelets and increased blood viscosity, which predispose to the formation of thrombotic diseases such as occlusive vasculitis, myocardial infarction, angina pectoris, ischemic stroke, hypertension, etc. Common causes of high erythrocyte electrophoresis index are myeloproliferative disorders, such as primary thrombocythemia and true erythrocytosis, which can cause high erythrocyte electrophoresis index. Secondly, in patients with diabetes mellitus and hyperlipidemia, there is an increase in resistance to erythrocyte electrophoresis due to increased blood glucose and lipids, so the erythrocyte electrophoresis index can be high. If you have a high erythrocyte electrophoresis index, you should first have a routine blood test to see if the number of red blood cells is increased, and a lipid test and a blood glucose test to see if the lipid level and blood glucose level are increased.
