Guided Distal Blood Draw for Hepatic Catheter Placement (Venous Access)

What Is This Test For?

This test uses imaging guidance to confirm the accurate positioning of a catheter inserted near your liver. It helps healthcare providers avoid complications like puncturing organs or blood vessels during procedures like central line placement or repeated blood draws.

How Is the Sample Collected?

A healthcare professional will insert a thin, flexible tube (catheter) into a vein near your liver under ultrasound or fluoroscopy guidance. Blood samples may be collected through this catheter for testing, or it may be used for other treatments. The process is generally quick and may cause mild discomfort.

Why Might You Need This Test?

You may need this test if you require frequent blood draws, need long-term intravenous access for treatments, or if your healthcare provider suspects the catheter is not positioned correctly. It’s also used in procedures like liver biopsies or drainage of fluids near the liver.

What Happens During the Procedure?

After cleaning the insertion site, the healthcare provider will guide the catheter into the correct location using real-time imaging. Blood samples may be drawn through the catheter, or it may be used for other medical purposes. You’ll likely be asked to stay still while the procedure is performed.
