What is the procedure of FNAC?

Overview: FNAC or Fine Needle Aspiration Cytology involves using a thin, hollow needle to remove samples of cells from tissue or fluid in an organ or a lump. This is usually done to identify the type of cells inside a lump found in the breast or a gland in the neck, like the thyroid gland.

How many methods of FNAC are there?

For the spreading, there are two methods that are widely used and recommended for different types of material. The “one-step method” is preferred for scant and dense material, like the one taken from the majority of breast solid masses. The “two-step method” is used mostly for liquid and hemorrhagic material.

What is the aim of FNAC?

Fine needle aspiration cytology (FNAC) is used to take cells from palpable nodules in organs or tissues. The purpose of this examination is to categorise the type of lesion responsible for its occurrence.

What is difference between biopsy and FNAC?

The sampling and biopsy considered together are called fine-needle aspiration biopsy (FNAB) or fine-needle aspiration cytology (FNAC) (the latter to emphasize that any aspiration biopsy involves cytopathology, not histopathology). Fine-needle aspiration biopsies are very safe minor surgical procedures.

Which needle is used for FNAC?

Fine needle aspiration cytology (FNAC) entails using a narrow gauge (25-22G) needle to collect a sample of a lesion for microscopic examination. It allows a minimally invasive, rapid diagnosis of tissue but does not preserve its histological architecture.

What are the advantages of FNAC?

The main advantages of FNAC are minimal invasiveness, reduced cost, pathological assessment of small lesions, which are not amenable to CNB. Moreover, it allows same day diagnosis of breast cancer and the identification and management, on the same day, of those patients with benign disease.

Which staining is used for FNAC?

MGG stain is performed on air-dried material and is preferred for an accurate evaluation of the cytoplasm and background. Cells generally appear larger than they are stained with Papanicolaou. H&E has similar advantages and disadvantages as Papanicolaou staining, but it is less used in cytology ( c).

What happens if FNAC is positive?

What happens if the FNAC test is positive? A positive FNAC test does not necessarily indicate cancer. Your doctor may recommend additional tests to establish a final diagnosis based on your medical history, complaint, signs and symptoms, and clinical examination.

Can FNAC be done twice?

It was found that the overall diagnostic results improved after repeating the FNAC. It can be concluded that repeating FNAC is useful and should be considered under some circumstances, especially in the case of non-diagnostic cervical lymph node aspirates.

How long is FNAC test?

The entire procedure from start to finish generally takes around 20 to 30 minutes if ultrasound is used.

Can FNAC detect TB?

Fine Needle Aspiration Cytology (FNAC) provides an inexpensive, quick and safe alternative to histopathology for the diagnosis of tuberculosis. It’s a patient friendly technique and provides a good assessment of cytomorphological features.

Why FNAC is done for thyroid?

The fine-needle aspiration is also performed to treat thyroid cysts. A thyroid cyst is a fluid-filled sac within the thyroid gland. Aspiration of the cyst with a needle and syringe can shrink the swelling from the cyst and the fluid removed can be analyzed for cancer.

What is the cost of FNAC?

The lowest FNAC test price is ₹270 only….FNAC Test Cost in India & Lab Details.

Which is more accurate biopsy or FNAC?

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].

Is FNAC test accurate?

Overall, the sensitivity of FNAC diagnosis was found to be 95.2%, specificity was 68.4%, positive predictive value was 83.3%, negative predictive value was 89.6%, and accuracy was 85.14%.

Is FNAC painful?

FNAC is generally well-tolerated procedure with most patients experiencing either mild pain or no pain during the procedure. No patients experienced severe pain.
