Thyroid FNAC (Fine Needle Aspiration Cytology) is a minimally invasive diagnostic procedure used to evaluate thyroid nodules, lumps, or abnormal growths detected during a clinical examination or ultrasound scan. It helps doctors examine thyroid cells under a microscope and determine whether a nodule is benign or requires further evaluation.
When Is Thyroid FNAC Recommended?
A doctor may recommend a thyroid FNAC test when an ultrasound identifies a thyroid nodule with features that require further assessment. It may also be advised for an enlarging thyroid lump, suspicious ultrasound findings, or to help determine the appropriate treatment approach.
How Is Thyroid FNAC Performed?
During the procedure, a thin needle is carefully inserted into the thyroid nodule, usually with ultrasound guidance, to collect a small sample of cells. The sample is then sent to a pathology laboratory for cytological examination. The procedure generally takes only a short time and does not usually require major preparation.
What Happens After Thyroid FNAC?
The collected sample is examined by a qualified pathologist, and the findings are discussed with the treating doctor. Depending on the result, patients may be advised routine monitoring, additional tests, repeat FNAC, or further treatment.
