Cytology of Fine Needle Aspiration (FNA) of Deep Tissue (e.g., Soft Tissue)
This test examines cells collected from a small sample taken with a fine needle from deeper tissues, such as muscles, lymph nodes, or other soft tissue areas. It helps diagnose conditions like tumors, infections, or inflammation.

Why This Test Is Done
Your doctor may recommend this test if you have symptoms like unexplained lumps, swelling, or pain in a specific area of your body. It can also be used to investigate suspected infections, cysts, or cancers in soft tissues.
How the Test Is Performed
A healthcare provider will use a thin needle to collect cells from the targeted tissue. The sample is then sent to a lab for microscopic examination by a pathologist.
What to Expect Before the Test
You may need to avoid certain medications or fasting, depending on the specific procedure. Discuss any concerns or allergies with your doctor beforehand. Local anesthesia is often used to minimize discomfort.
What to Expect During the Test
The procedure usually takes a few minutes. You might feel slight pressure or discomfort, but it’s generally well-tolerated with anesthesia. Recovery is quick, and you can resume normal activities immediately.
Reference range
Adult: 136-145 mmol/LN/A
Inform your healthcare provider if you are taking blood thinners. No special preparation required.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test plays a critical role in diagnosing conditions such as cancer (e.g., lymphoma, sarcomas), infections (e.g., abscesses), or inflammatory diseases. Early detection can guide treatment decisions and improve outcomes.
