FNAC Test in Delhi: Complete Guide to Procedure, Types, Cost & Results

The FNAC test in Delhi (Fine Needle Aspiration Cytology) is one of the most common and valuable diagnostic procedures performed in pathology. If your doctor has recommended an FNAC test in Delhi, this comprehensive guide explains everything you need to know — what FNAC is, why it is done, who needs it, the procedure steps, preparation, results interpretation, cost, and why Edge Imaging & Diagnostics in Paschim Vihar, West Delhi is your best choice for this test in Delhi NCR.

An FNAC test in Delhi is a quick, minimally invasive, and cost-effective test that provides vital diagnostic information about lumps, swellings, and abnormal lymph nodes throughout the body — often within the same day as the procedure. Patients who choose Edge Imaging & Diagnostics for their FNAC test in Delhi receive expert cytological analysis with fast reporting and accurate diagnosis.

What is an FNAC Test?

The FNAC test (Fine Needle Aspiration Cytology) is a minimally invasive diagnostic procedure in which a thin, hollow needle (22–25 gauge) is used to aspirate cells from a lump, nodule, cyst, or mass in the body. The aspirated cellular material is spread on glass slides, stained, and examined under a microscope by a cytopathologist to identify the nature of the cells — whether they are inflammatory, benign, pre-cancerous, or malignant (cancerous).

FNAC provides cell-level information (cytology) rather than tissue architecture (histology). This distinction is important — FNAC is excellent for initial diagnosis and screening, while core needle biopsy or surgical biopsy may be needed for complete histological classification of some conditions, particularly lymphomas.

FNAC can be performed with or without imaging guidance. For superficial, easily palpable lumps, the procedure is performed by clinical palpation. For deeper, non-palpable lesions in the breast, thyroid, liver, kidney, or lymph nodes, ultrasound-guided FNAC is performed at Edge Imaging & Diagnostics in Paschim Vihar, Delhi to ensure precise targeting and maximise diagnostic yield.

Why is an FNAC Test Done?

FNAC is an invaluable first-line investigation for evaluating a wide range of lumps and swellings. Common reasons for FNAC in Delhi include:

• Thyroid nodule evaluation: Determines whether a thyroid lump is benign (colloid nodule, adenoma) or malignant (papillary thyroid cancer, follicular carcinoma).
• Lymph node assessment: Evaluates enlarged lymph nodes in the neck, axilla, or groin — for infection, tuberculosis, lymphoma, or metastatic cancer.
• Breast lump diagnosis: Distinguishes benign breast lesions (fibroadenoma, cyst) from breast cancer.
• Salivary gland masses: Parotid and submandibular gland lumps evaluated for benign versus malignant conditions.
• Soft tissue swellings: Lipomas, ganglia, sebaceous cysts, and other soft tissue lumps assessed.
• Liver and kidney lesions: Focal lesions detected on imaging investigated with ultrasound-guided FNAC.
• Lung mass: CT-guided FNAC for peripheral lung masses to determine malignancy.

Who Needs an FNAC Test?

You may need an FNAC test in Delhi if you have:

• A new or growing lump anywhere in the body
• An enlarged lymph node in the neck, armpit, or groin lasting more than 4 weeks
• A thyroid nodule identified on ultrasound or examination
• A breast lump that your doctor wants to investigate
• A salivary gland or parotid swelling
• A deep organ lesion identified on ultrasound, CT, or MRI requiring tissue sampling
• Any mass or swelling for which your doctor wants cytological information before deciding on further management

Symptoms That May Lead to an FNAC Test

• A noticeable lump or swelling under the skin, in the neck, armpit, breast, or groin
• Rapidly enlarging mass anywhere in the body
• Thyroid swelling (goitre) or a discrete nodule in the neck
• A breast lump detected by self-examination or mammography/ultrasound
• Enlarged lymph nodes accompanied by fever, weight loss, or night sweats
• Deep abdominal or pelvic mass detected on imaging

Preparation Before an FNAC Test

FNAC is a simple outpatient procedure requiring minimal preparation:

• No fasting required for most FNAC procedures performed under local anaesthesia or without anaesthesia.
• Blood thinners: Inform your doctor if you are taking aspirin, clopidogrel, warfarin, or other anticoagulants. Stopping may be advised 3–5 days before, depending on the site of FNAC.
• Imaging reports: Bring any relevant ultrasound, CT, or MRI reports and the referral letter from your doctor.
• No special preparation is needed for superficial (palpable) FNAC of lymph nodes or thyroid.
• For ultrasound-guided FNAC of deep lesions, fasting for 2–4 hours may be required in selected cases.

Step-by-Step FNAC Procedure

Here is a detailed account of what happens during an FNAC test at Edge Imaging & Diagnostics in Paschim Vihar, Delhi:

1. Patient positioning: You are positioned appropriately depending on the site — lying down for neck, breast, or abdominal FNAC; sitting for some lymph node locations.
2. Skin preparation: The skin over the target area is cleaned with antiseptic. Sterile drapes are applied for ultrasound-guided procedures.
3. Localisation: For palpable lesions, the doctor locates the lump by feel. For non-palpable deep lesions, real-time ultrasound guidance is used to precisely target the abnormal area.
4. Local anaesthesia (optional): For larger or deeper sites, a small amount of lidocaine may be applied to the skin. Many FNAC procedures require no anaesthesia at all due to the fine needle used.
5. Needle insertion: A 22–25 gauge fine needle attached to a 10–20 mL syringe is inserted into the target lesion. This causes a brief sharp sensation.
6. Aspiration: Gentle negative pressure is applied while the needle is moved within the lesion in a to-and-fro motion to aspirate cells.
7. Needle withdrawal: The needle is withdrawn. The procedure typically takes less than 30 seconds for each pass.
8. Multiple passes: 2–4 passes are usually made from slightly different angles to maximise cellular yield and sampling adequacy.
9. Slide preparation: The aspirated material is immediately spread onto glass slides, fixed, and stained (Giemsa/Papanicolaou) for cytological examination.
10. Rapid on-site evaluation (ROSE): Where available, a cytotechnologist reviews the slides immediately to confirm adequacy of the sample before you leave.

What Happens After an FNAC Test?

• A small adhesive dressing is placed over the needle entry point. No sutures required.
• You can resume normal activities immediately after the procedure.
• Mild tenderness or bruising at the biopsy site may occur and resolves within a few days.
• FNAC results are typically available within 24–48 hours. Urgent results may be provided the same day.
• Your referring doctor will discuss the cytology report and recommend next steps based on the findings.

Risks and Complications of FNAC

FNAC is one of the safest diagnostic procedures available. Complications are rare:

• Minor bleeding or bruising: The most common minor complication — resolves within days without treatment.
• Infection: Extremely rare with sterile technique.
• Inadequate sample: Sometimes insufficient cells are obtained — a repeat FNAC or core needle biopsy may then be recommended.
• Pneumothorax: Very rare risk for lung or deep thoracic FNAC — managed promptly if it occurs.
• Tumour seeding: Theoretical concern with very fine needles — evidence suggests this risk is negligible in clinical practice.

Benefits of FNAC Test

• Minimally invasive — no surgical incision required
• Very fast procedure — completed in 5–15 minutes
• Results available within 24–48 hours — rapid clinical decision-making
• Extremely safe with minimal complications
• Cost-effective compared to surgical biopsy
• No general anaesthesia required for most procedures
• Can be combined with ultrasound guidance for deep or non-palpable lesions

FNAC Test Accuracy and Reliability

FNAC has a diagnostic sensitivity of 85–98% for well-differentiated epithelial malignancies such as thyroid cancer, breast cancer, and metastatic carcinoma. Specificity (correctly identifying benign lesions) exceeds 95%. For lymphomas and some soft tissue tumours, FNAC provides preliminary information but core needle biopsy with immunohistochemistry is often needed for complete classification. At Edge Imaging & Diagnostics in Paschim Vihar, Delhi, ultrasound-guided FNAC is performed by experienced radiologists to maximise sample adequacy and diagnostic accuracy.

Frequently Asked Questions About FNAC Test

1. Is an FNAC test painful?

An FNAC test causes only a brief, mild sharp pain similar to a routine blood test. The needle used is very thin (22–25 gauge). Most patients tolerate the procedure without any anaesthesia. Local anaesthetic cream or injection can be applied if you are particularly sensitive.

2. How long does an FNAC test take?

The actual FNAC procedure takes only 5–15 minutes. The complete visit including registration, preparation, procedure, and dressing takes approximately 30–45 minutes. You can return to normal activities immediately afterwards.

3. When will I get my FNAC test results?

FNAC cytology results are typically available within 24–48 hours. Urgent oncology cases can often be reported the same day. Your referring doctor will discuss the cytopathology report findings with you at your follow-up appointment.

4. What is the difference between FNAC and biopsy?

FNAC uses a fine needle to aspirate individual cells (cytology) — fast, simple, minimal discomfort. Core needle biopsy uses a larger needle to take a tissue cylinder (histology) — provides architectural tissue information essential for complete diagnosis of lymphoma and some other cancers. FNAC is the first-line investigation; biopsy follows if needed.

5. Can FNAC diagnose cancer?

Yes. FNAC can diagnose most common cancers with high accuracy — thyroid cancer, breast cancer, metastatic carcinoma, and salivary gland malignancies. For lymphoma and some soft tissue sarcomas, histological core needle biopsy is needed for complete characterisation and treatment planning.

6. Is FNAC test safe?

FNAC is one of the safest diagnostic procedures available. It uses a fine needle thinner than those used for blood tests. Complications such as bleeding, infection, or bruising are rare and minor. The procedure is performed daily in thousands of patients worldwide.

7. What does “inadequate sample” mean on an FNAC report?

An inadequate or unsatisfactory sample means insufficient cells were obtained for confident cytological diagnosis. This occurs in 5–15% of FNAC procedures. A repeat FNAC with ultrasound guidance or a core needle biopsy will then be recommended.

8. Can FNAC diagnose tuberculosis?

Yes. FNAC of enlarged lymph nodes can identify caseating granulomas characteristic of TB, positive ZN stain for acid-fast bacilli, and the aspirated material can be sent for TB PCR and culture for confirmation and drug sensitivity testing.

9. Is ultrasound-guided FNAC better than palpation-guided FNAC?

Ultrasound-guided FNAC is significantly more accurate for non-palpable lesions, small nodules, and deep structures. It improves sample adequacy rates and reduces the likelihood of sampling error. At Edge Imaging & Diagnostics, we recommend ultrasound guidance for all thyroid, breast, and deep lesion FNAC procedures.
