How is the Test Performed?

The test is usually done in the hospital. You may be given a sedative or pain medication by injection before the test. If the approach is through the abdominal wall, you will be lying on your back with your right hand under your head. It is important to be as still as possible.

The health care provider will examine the liver and determine the correct spot for the biopsy needle to be inserted. The skin will be cleansed, and a small needle will be used to inject a local anesthetic to numb the area. A small incision is made, and the biopsy needle is inserted. You will then be instructed to hold your breath while the biopsy is taken. This is to reduce the chance of puncturing the lung or tearing the liver.

The needle is inserted and removed quickly. Pressure will be applied to stop bleeding, and a bandage is placed over the insertion site.

If the procedure is performed by the transjugular approach, you be lying on your back on a table. The internal jugular vein in the neck will be located. The skin will be cleansed, and a small needle will be used to inject a local anesthetic to numb the area. A needle is then inserted to pass a catheter that is moved down to the liver. X-ray equipment will be used to check the location of the catheter. A specialized needle is then used through the catheter to obtain the biopsy sample.
