A routine blood test for cholecystitis usually looks at the white blood cell count, white blood cell classification, red blood cell count, hemoglobin, and platelet count. In acute cholecystitis, the blood test may show an increase in white blood cell count, neutrophil number and percentage, and these values will usually return to normal after anti-infective treatment. In chronic cholecystitis, the white blood cell count and white blood cell classification may be normal or elevated. If chronic cholecystitis causes dyspepsia, steatorrhea, etc., there may be a decrease in the red blood cell count, hemoglobin, and anemia. Cholecystitis generally has little effect on platelets, etc., and usually does not affect platelet values. If cholecystitis occurs, it is recommended to go to the hospital in time to improve the relevant examination, and to clarify the diagnosis and standardize the treatment, so as not to delay the condition.
