Diagnostic Accuracy of Total Leucocyte Count and Ultrasound in the Diagnosis of Acute Appendicitis

Background: To compare the diagnostic accuracy ofTotal Leucocyte Count (TLC) with Ultrasound (USG)abdomen and pelvis in diagnosis of acute appendicitis.Methods: In this cross sectional study 100 patients, withclinical diagnosis of acute appendicitis, were included. Inhistopathologically dignosed cases, TLC and ultrasound(USG) abdomen and pelvis findings were compared.. ChiSquare test was used to find correlation.Results: The mean age was 30.17 years. The sensitivity,specificity, positive predictive and the negative predictivevalue of total leukocyte count was 87.5 %, 78.6%, 91.3%and 71.0%, respectively. The sensitivity, specificity,positive predictive and the negative predictive value ofUSG abdomen and pelvis was 44%,89.3%,91.4% and 38.5%,respectively.Conclusion: TLC has more sensitivity and diagnosticaccuracy in acute appendicitis in comparison to USGabdomen and pelvis. As diagnosis in acute appendicitis ismore clinical, hence it can be used alone to enhancediagnostic accuracy
