 Lymph node biopsyHow the Test is Performed:The test is done in the hospital. There are 2 ways the sample may be obtained: a needle biopsy or an open biopsy. A needle biopsy involves inserting a needle into a node to obtain the sample. You will be asked to lie on the examination table. The biopsy site will be cleansed, and a local anesthetic will be injected. The biopsy needle is then inserted into the node. A sample is removed, pressure is applied to the site to stop the bleeding , and a bandage is applied. An open biopsy consists of surgically removing a part or all of a node. You will be asked to lie on the examination table. The skin over the biopsy site is cleansed, and a local anesthetic is injected (occasionally, a general anesthetic is given). A small incision is made and the entire lymph node or a part of the lymph node is removed. The incision is then closed with stitches and bandaged. The biopsy is then sent to the laboratory for examination. How to Prepare: Tell your health care provider about any drug allergies , which medications you are taking, if you have bleeding problems, and if you are pregnant . You must sign a consent form. Infants and children: The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust.
