Original Article



Fine Needle Aspiration Cytology (FNAC) is an initial diagnostic test that has been found to be simple and cost effective but it is associated with pitfalls due to difference in correlations between FNAC and Histopathological Examination (HPE).


A study was undertaken with a total of 112 patientspresenting with thyroid nodule who underwent thyroid surgeries. Preoperative FNAC and postoperative HPE were evaluated to calculate sensitivity, specificity, positive and negative predictive value and accuracy.


In our study we found sensitivity to be 81.48%, specificity 95.29%, positive predictive value 84.61%, Negative predictive value 94.18% and accuracy to be 91.16%.


Thus we can conclude that FNAC is a simple, safe and cost-effective diagnostic modality in the investigation of Thyroid nodule with high specificity and accuracy.
