Liver Function Test with Fine Needle Aspiration (FNA) Guidance Support (Substance Content, Qualitative)
This test involves assessing liver function and providing guidance for a procedure called fine needle aspiration (FNA) to help diagnose liver conditions. It may include evaluating liver enzymes, protein levels, or other biomarkers in blood.

What This Test Measures
The test evaluates key components of liver function, such as protein levels (e.g., albumin), enzyme activity (e.g., bilirubin, liver enzymes), and other substances that reflect liver health. Guidance is provided to support a needle aspiration procedure, which may involve examining cells from the liver for further diagnosis.
Why It’s Done
Your doctor may order this test if you have symptoms like jaundice (yellowing of skin/eyes), unexplained weight loss, fatigue, or liver-related issues. It’s also used when planning a liver biopsy or FNA to ensure accurate diagnosis and safe procedure guidance.
Sample Collection and Procedure Guidance
A blood sample is typically drawn to measure liver-related substances. The FNA guidance part involves imaging or ultrasound to help a healthcare provider safely place a needle into the liver for cell sampling. This is usually done under imaging supervision.
Preparation
No special preparation is needed for the blood test, but you may be asked to fast for 8–12 hours before if enzymes are measured. For the FNA procedure, follow your doctor’s instructions, which may include avoiding certain medications or foods.
Reference range
Adult: 136-145 mmol/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
