Alternative Names Abdominal wall biopsy; Biopsy - abdominal wall fat pad How the test is performed Needle aspiration is the most common method of obtaining an abdominal wall fat pad biopsy. The skin of the abdomen is cleansed, and a local anesthetic may be used to numb the area. A needle is inserted through the skin and into the fat pad under the skin. A small core of the fat pad is removed with the needle and sent to the laboratory for analysis. How to prepare for the test No special preparation is usually necessary. How the test will feel Although your health care provider may have numbed the skin, there can be some mild discomfort or pressure during the needle insertion. Afterward, the area may feel tender or bruised for several days. Why the test is performed This test may be performed when amyloidosis is suspected. Normal Values The fat pad tissues are normal.
