Abstract

There are number of tests used to determine function of thyroid which are hormonal assays; radioactive isotopes study, nuclear scan etc. but today’s most widely used and simplest test is FNAC. The FNAC, when supported by clinical methods and other investigations such as USG, serum, T3, T4, THS levels can help the physician or surgeon, to take proper decision for the management of the patient. The present study planned to correlate the cytological diagnosis wherever possible with FNAC and establish their relationship. Aim: The study analyse the thyroid lesions by FNAC and also correlate the cytological diagnosis hormones wherever possible and establish their relationship. Materials and methods: The needles, syringes, slides and fixatives are used for FNAC. The chemiluminescence thyroid function test measures the levels of thyroid hormones in FNAC encountered patients. Results: Out of 100 cases, only 60 cases are correlated and confirmed histo-pathologically. Out of these 60 cases, 48 cases (80%) were found to be non-neoplastic and 12 cases (20%) were found to be neoplastic lesions. Conclusion: There is 93% diagnostic accuracy in cytological and histo-pathlogical correlation. It can be safely used in diagnosis of most of thyroid lesion without any serious complication. There was no correlation between thyroid hormones levels and the result of FNAC. Thus thyroid function tests cannot be considered selective and specific to predict the cytological diagnosis
