Lymph node cultureDefinition Lymph node culture is a laboratory test performed on a lymph node to identify organisms (bacteria, viruses, and fungus) that cause infection. How the test is performed A needle aspiration or biopsy of an enlarged lymph node (swollen glands) is obtained. The fluid is placed in culture media and observed for growth in the laboratory. Sometimes special stains are also done. How to prepare for the test There is no special preparation necessary. How the test will feel The site may be numbed with a local anesthetic before the node is aspirated. There may be some pain when the needle is inserted into the lymph node. Why the test is performed The test may be performed if the cause of swollen glands is not known, and infection is suspected. Normal Values No growth is normal. What abnormal results mean Abnormal results indicate that infectious microorganisms, such as bacteria, viruses, or fungus are present. Suspicion of atypical mycobacterial infection is an additional condition under which the test may be performed. What the risks are There is a risk of bleeding or infection. Special considerations Not applicable. Illustrations
