White blood cell count is a poor predictor of severity of disease in the diagnosis of appendicitis.
The white blood cell (WBC) count is considered to be a useful test in the diagnosis of appendicitis. The purpose of this study was to examine the clinical features of patients with normal WBC appendicitis and also to determine whether a higher WBC count correlates with a more advanced stage of appendicitis. Patients with pathologically confirmed appendicitis from January 1989 to December 1994 were included in the study (n = 1919). ⋯ The severity of disease of patients with a normal WBC count were: 1 = 58 per cent; 2 = 13 per cent; 3 = 7 per cent; and 4 = 22 per cent. For patients with an elevated WBC count the scores were: 1 = 57 per cent; 2 = 17 per cent; 3 = 13 per cent; and 4 = 14 per cent. The proportion of gangrenous and perforated appendicitis in the patients with a normal WBC count is the same as in the patients with an elevated WBC count.
