What is a Fnac sample?
Background: Fine Needle Aspiration Cytology (FNAC) is a simple, quick and inexpensive method that is used to sample superficial masses like those found in the neck and is usually performed in the outpatient clinic. It causes minimal trauma to the patient and carries virtually no risk of complications.
How do you do a Fnac test?
FNAC Test Procedure. The needle is inserted on the area in question. Negative pressure is exerted in the needle and with the motion of insertion, the specimen is taken. The sensation on insertion is more similar to that of the blood test. A number of insertions are done to get an adequate sample.
What is fine needle aspiration cytology (FNAC)?
Fine needle aspiration cytology or an FNAC is a diagnostic test that is used to check if a lump or a mass on the body is cancerous in nature. As the name suggests, this test is performed using a needle. A small amount of tissue, which needs to be analysed, is scraped and sent to a laboratory for analysis.
What is the role of Fnac in medicine?
An often overlooked and underemphasized use of FNAC in medicine is its role in investigating cytological changes. Needle aspiration is safer and less traumatic than biopsy based on surgical methods. Today, it is the most used and recommended procedure for the accurate diagnosis of cancer and conditions caused by inflammation.
Is FNAC a painful procedure?
FNAC is generally well-tolerated procedure with most patients experiencing either mild pain or no pain during the procedure. No patients experienced severe pain. There was no difference in VAS scores between lymph node biopsy and salivary gland biopsy.
How FNAC test is performed?
The needle may have a syringe attached during FNAC biopsies. When a syringe is used, suction is applied to allow more material to be obtained. The needle is inserted and drawn in and out for a period of about five seconds and then withdrawn. The material is then smeared on a glass slide.
How do I prepare for FNAC test?
You do not need to do much to prepare for a fine needle aspiration biopsy. Your doctor may ask you to temporarily stop taking certain medications a few days before the test, including blood thinners such as aspirin, clopidogrel (Plavix), and warfarin (Coumadin).
How long is FNAC procedure?

Is fine needle aspiration painful?
Generally, the procedure is not painful. Results are as accurate as when a tissue sample is removed surgically.
Which is better FNAC or biopsy?
Studies carried out by Homesh NA et al., Usami S et al., to compare CNB & FNAC have reported very high sensitivity (91–99%), specificity (96–100%), positive predictive value (100%), and negative predictive value (100%) for CNB which are better than results for FNAC for both palpable and nonpalpable lesions [20,21].
What happens if FNAC is positive?
When FNAC shows a positive finding, treatment should be given accordingly as FNAC has a high PPV. However, when FNAC shows a negative result, malignancy cannot be reliably ruled out since the NPV of FNAC is low (37%). PET/CT is then performed in these patients.

What is US FNAC?
Aim: Surgeon-performed ultrasound-guided fine needle aspiration cytology (US-FNAC) and radiologist-performed US-FNAC are both accepted forms of thyroid nodule assessment. To date there have been no studies comparing cost of evaluation between these two models. The aim of this study is to compare surgeon-performed thyroid US-FNAC to radiologist-performed US-FNAC. The primary outcome of interest was cost of surgeon-performed US-FNAC compared to cost of radiologist-performed US-FNAC. Secondary outcome of interest was time to treatment decision.
How many patients were included in the analysis of the USFNAC?
Results: There were 92 patients included in the analysis. Forty-two underwent surgeon-performed US-FNAC and 50 underwent radiologist-performed US-FNAC. Mean cost in surgeon-performed US-FNAC was $653 compared to $1017 in radiologist-performed US-FNA. Time from first appointment to definitive management plan was 47 days in surgeon-performed USFNAC and 116 days in radiologist-performed US-FNAC.
HOW IS A THYROID FNA PERFORMED?
A local or topical anesthetic may be applied. For the biopsy, your doctor will use a very thin needle to withdraw cells from the thyroid nodule. The needle used is smaller in diameter than those used in most blood draws. Your doctor will insert the needle through the skin and into the thyroid nodule. After the sampling, which only takes several seconds, the needle will be removed. New needles are used for additional samples. Several samples of cells will be obtained, by sticking a fine needle in various parts of the nodule usually between two and six times . This assures a better chance to find cancerous cells if they are present. If there is fluid in the nodule, a syringe may be used to drain it.
HOW LONG DOES IT TAKE FOR THE RESULTS TO RETURN?
Generally, it can take anywhere from a few days to two (2) weeks for the result to return.
