Pak J Med Health Sci Jan ;7(3):716-8.

The aim of this study is to establish efficacy of FNAb of thyroid nodules. This retrospective study was carried out from January 2007 to June 2013. Total of 487 cases were studied who had ultrasound guided thyroid FNA biopsy. The diagnostic yield of initial FNAb was 82.6%, with two out of 13 indeterminate lesions turned out malignant. Sensitivity, specificity, positive predictive value and negative predictive value were 82.7%, 99.7%, 93.3% and 99.3% respectively. Results of our study are quite comparable with other published literature.
