Description
Sample Required:
For an ultrasound-guided fine-needle aspiration cytology (FNAC), a sample is obtained using a thin needle, and the procedure is guided by ultrasound imaging.
Test Time:
The Ultrasound FNAC procedure typically takes around 30 to 60 minutes, depending on the specific area being aspirated.
Test Normal Range:
FNAC results are assessed by a pathologist or healthcare provider to determine the nature of the cells in the sample and identify any abnormalities or issues.
What is the Test?
Ultrasound-guided fine-needle aspiration cytology (FNAC) is a diagnostic procedure used to obtain a sample of cells from a specific area within the body for examination under a microscope. Ultrasound imaging is used to guide the placement of the thin needle into the target area.
Test Procedure:
During the Ultrasound FNAC, a gel is applied to the skin overlying the area of interest, and the ultrasound transducer is used to locate the target area. A thin needle is then inserted through the skin to collect a sample of cells for analysis.
When to Take the Test:
Ultrasound FNAC may be ordered by healthcare providers to investigate suspicious lumps, masses, or abnormalities detected on imaging, such as ultrasound or mammography.
Who Should Take This Test:
Individuals with suspicious lumps or masses, or those requiring a tissue sample for further analysis, may be candidates for Ultrasound FNAC. This test helps healthcare providers determine the nature of the cells within the targeted area.
Precautions for Exceptional Cases (Pregnancy, etc.):
Special precautions may be taken if the procedure is performed on pregnant individuals. The decision to proceed with ultrasound FNAC during pregnancy is based on a careful evaluation of risks and benefits.
Frequently Asked Questions (FAQs)
Q1: Is Ultrasound FNAC painful?
A: The procedure may cause some discomfort or pain, similar to the sensation of a needle prick. Local anaesthesia may be used to minimize pain during the procedure.
Q2: Can Ultrasound FNAC detect all types of abnormalities?
A: Ultrasound FNAC is effective in obtaining samples for cytological examination, helping to diagnose or rule out certain conditions. However, it may not provide a definitive diagnosis in all cases, and additional tests may be required.
Q3: How should I prepare for the test?
A: Follow any pre-procedure instructions provided by the healthcare provider. In some cases, fasting or discontinuation of certain medications may be recommended.
Q4: Is Ultrasound FNAC safe during pregnancy?
A: The decision to perform FNAC during pregnancy is made carefully, considering the potential risks and benefits. Special precautions may be taken to minimize any potential harm to the fetus.
Q5: What can Ultrasound FNAC reveal?
A: Ultrasound FNAC provides a sample of cells for cytological examination, helping to identify the nature of the cells within the targeted area. It is valuable for diagnosing or ruling out certain conditions and guiding further treatment decisions.
