Lymph node culture is a laboratory test performed on a lymph node to identify microorganisms (bacteria, viruses, and fungi) that cause infection and lymph node swelling.
Culture - lymph node
How the test is performed
A sample of fluid from a lymph node is needed. This may be done using a needle to draw out fluid (aspiration) or during a lymph node biopsy .
The sample is sent to a laboratory where it is placed in a special dish and watched to see if bacteria, fungi, or viruses grow. This is called a culture. Sometimes special stains are also used to identify specific cells or microorganisms.
If needle aspiration does not provide a good enough sample, the entire lymph node may be removed and sent for culture and other testing.
How to prepare for the test
There is no special preparation needed for the lab test. For information on how to prepare for the lymph node sample, see lymph node biopsy .

When melanoma has reached Stage III , it frequently means that cancer has spread to the lymph nodes closest to the original cancer site. In Stage IV, many of the body’s lymph nodes are affected. When skin cancer is detected, doctors examine the closest lymph nodes to determine if the cancer has spread. If so, they may need to be removed.
Depending on the spread of cancer, surgery to remove lymph nodes , lymphadenectomy, can be quite extensive and involve a hospital stay of up to 5 days and a recovery of weeks. And, the larger the incision to remove the lymph nodes, the greater the chance for infection. Removing all of the lymph nodes in the groin area, for example, can require an incision of 12 inches, going from the hip to the thigh. For some, getting back to normal activities doesn’t happen for 6 weeks or more.
