Basic Information
FNAC For Superficial Palpable Lumps
An inexpensive rapid test for diagnosis of superficial palpable masses
Fine Needle Aspiration Cytology (FNAC) is a simple, quick & inexpensive method to sample superficial suspicious masses such as palpable lymph nodes, thyroid nodules, breast, or any other lump in the body. Cytological examination of a smear made from aspirate can lead us to a definitive diagnosis early. It can rule out cancer, which is a significant worry that alleviates patent anxiety in many cases. Results: The stained smears from the aspirate are examined under a microscope, & a diagnosis based on the type of cells seen is reached. In some cases, the opinion may be inconclusive, & the actual diagnosis may require further testing, usually involving a surgical biopsy.
Benefits and Limitations: FNAC is a rapid, effective test for determining the status of the suspect tissue. Compared to surgical biopsy, FNAC is an OPD procedure that causes minimal trauma, infection or scarring with minimal recovery time. Once the test is completed, the patient can continue normal activities. Smear prepared from the aspirate obtained through the procedure is stained, examined under a microscope, and an opinion is given.
FNA for Confirmation of MTB-Tuberculosis: In cases with Granulomatous lymphadenitis or purulent aspirates, Xpert MTB (CBNAAT) testing has an important role in confirming Extra Pulmonary Tuberculosis (EPTB).

Reattach needle. Express aspirate. Make smear.
Combining FNA with Xpert MTB (CBNAAT) can detect FNA missed cases, and significant numbers of cytomorphological TB NEGATIVE aspirates can be confirmed or diagnosed by Xpert MTB (CBNAAT). The Gene Xpert MTB/RIF is a fully automated diagnostic molecular test which simultaneously detects TB & RIF drug resistance. Implementing the Gen Xpert assay may dramatically improve the rapid diagnosis of Lymph Node TB/ extra pulmonary TB. The priority of Xpert MTB/ RIF as a diagnostic method of MTB is attributed to its feasibility, rapid turnaround time, reliability & high sensitivity & specificity, even in very low bacterial load.
