A step-by-step guide from scheduling through results — so you know exactly what's coming and feel confident walking in.
Thyroid fine needle aspiration (FNA) biopsy is one of the most commonly performed office procedures in thyroid medicine. It's quick, minimally invasive, and requires no sedation. Most patients are surprised by how straightforward the experience is.
With Dr. Parikh, your biopsy visit is designed around your comfort and efficiency. You'll meet Dr. Parikh, review your imaging, have the procedure performed (if indicated), and leave the same day — all without needing a separate appointment.
Do not stop taking prescription blood thinners (warfarin, Eliquis, Xarelto, Plavix) without first speaking with your prescribing physician. Over-the-counter aspirin can typically be paused if medically appropriate, but confirm with your doctor before doing so. Please let us know about all medications when you schedule.
Unlike many procedures, thyroid FNA biopsy requires no fasting. Eat and drink normally before your appointment. Take your regular morning medications as usual unless specifically instructed otherwise.
Yes — a support person is always welcome. They can accompany you into the consultation and wait during the procedure if you prefer. You do not need someone to drive you home, but you're welcome to bring them.
Knowing exactly what to expect makes the experience significantly less stressful. Here's the procedure, minute by minute.
You'll lie on an exam table with your neck slightly extended. A pillow or roll is placed under your shoulders for support. Dr. Parikh explains each step before doing it.
Dr. Parikh places an ultrasound probe on your neck to identify the nodule, map its location, and plan the safest needle path. This takes 2–3 minutes.
The skin over the biopsy site is cleaned with antiseptic solution. The area may feel cool. A small amount of local anesthetic may be applied.
A very fine needle (thinner than a typical blood draw needle) is guided into the nodule under real-time ultrasound imaging. You may feel mild pressure or a brief sharp sensation. The entire pass takes 15–30 seconds.
Typically 2–4 passes are made to collect an adequate sample. Between passes, Dr. Parikh checks image quality and confirms positioning. Most patients find this the most manageable part.
Gentle pressure is held on the site for a few minutes to minimize bruising. A small bandage is applied. You're done — typically within 15 minutes of starting.
Most patients describe mild discomfort — pressure and a brief pinch during each pass. Pain is typically rated 1–3 out of 10. Many patients are surprised by how tolerable it is. The anticipation is usually worse than the procedure itself.
Call (770) 282-9353 or go to the ER if symptoms are severe.
Thyroid biopsy results are reported using the Bethesda System — a standardized six-category classification that helps determine the appropriate next step.
| Bethesda Category | Meaning | Typical Next Step |
|---|---|---|
| I — Non-diagnostic | Insufficient cells for diagnosis | Repeat biopsy |
| II — Benign | No concerning features | Surveillance ultrasound |
| III — AUS/FLUS | Some atypical cells, uncertain | Molecular testing or repeat |
| IV — Follicular Neoplasm | Possible follicular tumor | Molecular testing or surgery |
| V — Suspicious for Malignancy | High concern for cancer | Surgery typically recommended |
| VI — Malignant | Consistent with thyroid cancer | Surgery with staging workup |
You will not receive results via a patient portal with no context. Dr. Parikh contacts you directly to walk through your results, what the Bethesda category means for your clinical situation, and what your options are going forward.
Cytology results are typically returned within 7–14 days of your biopsy. Dr. Parikh will reach out to you as soon as they are available. If molecular testing (e.g., ThyroSeq, Afirma) is ordered, allow additional time per the lab's reported turnaround.
Schedule or Ask a Question OnlineUnlike a radiologist who ends their involvement when you walk out the door, Dr. Parikh is with you through the entire journey.
Most thyroid nodule biopsies come back benign. Dr. Parikh will advise you on the appropriate surveillance schedule — typically a follow-up ultrasound in 12–24 months — and what changes would warrant re-evaluation.
For Bethesda III or IV, Dr. Parikh will discuss molecular testing options (ThyroSeq, Afirma Gene Expression Classifier) that can often clarify cancer risk and help avoid unnecessary surgery.
If your result is suspicious or malignant, Dr. Parikh walks you through the surgical options directly — no new referral required. He is already your thyroid surgeon and will guide you from diagnosis through treatment.
