The diagnostic value of C-reactive protein (CRP) was evaluated in 143 patients with acute abdominal pain, 67 men and 76 women with mean age of 48 ± 20 years old. Clinical and laboratory variables were collected after the patients' arrival at the emergency department. The attending clinicians did not consider the CRP value during the study period and did not use it for their management. When patients were grouped by final disposition, which was according to severity, only CRP and leukocyte count were identified as significant quantitative variables by multivariate analysis. CRP can detect the serious condition; ie, in 79% of the hospitalized group, although specificity was 64% the total accuracy was 73%. When elevated CRP was combined with leukocytosis, the diagnostic value was much improved, with specificity of 89% and positive predictive value of 88%. The sensitivity was improved to 90% when elevated CRP or leukocytosis was used. It is thus concluded that CRP is a helpful quantitative variable for disposition decision-making in patients with acute abdominal pain.
