Infected lymph nodes can be diagnosed through several tests, including physical examinations, blood tests to check for signs of infection or inflammation, and imaging studies like ultrasound, CT scans, or MRI. Additionally, a biopsy may be performed to analyze tissue from the lymph node for the presence of infection or cancer. These methods help determine the underlying cause and extent of the infection.

What does lymphadenopathy means?
Lymphadenopathy is the disease or enlargement of lymph nodes. Lymph nodes are small round structures that are present all over the body. They house cells (most commonly white blood cells) that are involved in protecting the human body from infections. Lymphadenopathy can occur due to a number of reasons: Infections - the most common reason Lymphomas and leukemias - cancers of white blood cells in the lymph nodes and blood Cancers in other body parts that sometimes spread to lymph nodes Diseases of the immune system, such as lupus and sarcoidosis Other uncommon diseases The neck, armpits and groin are the body parts where enlarged lymph nodes are most easily felt. The appearance of lumps in these areas is the most common sign of lymphadenopathy. To find out the cause of lymphadenopathy, doctors may advise tests that include a fine needle test (FNAC or a fine needle aspiration cytology) or the removal of a part or whole node (lymph node biopsy). The treatment of lymphadenopathy varies depending on the reason for lymph node enlargement.
Swollen lymph nodes?
DefinitionLymph nodes are found throughout your body. They are an important part of your immune system. Lymph nodes help your body recognize and fight germs, infections, and other foreign substances.The term "swollen glands" refers to enlargement of one or more lymph nodes.In a child, a node is considered enlarged if it is more than 1 centimeter (0.4 inch) in diameter.See also: Lymphadenitis and lymphangitisAlternative NamesSwollen glands; Glands - swollen; Lymph nodes - swollen; LymphadenopathyConsiderationsCommon areas where the lymph nodes can be felt (with the fingers) include:GroinArmpitNeck (there is a chain of lymph nodes on either side of the front of the neck, both sides of the neck, and down each side of the back of the neck)Under the jaw and chinBehind the earsOn the back of the headLymph nodes can become swollen from infection, inflammatory conditions, an abscess, or cancer. Other causes of enlarged lymph nodes are rare. By far, the most common cause of swollen lymph nodes is infection.When swelling appears suddenly and is painful, it is usually caused by injury or an infection. Enlargement that comes on gradually and painlessly may, in some cases, result from cancer or a tumor.Common CausesInfections that commonly cause swollen lymph nodes include:Abscessed or impacted toothEar infectionColds, flu, and other infectionsGingivitisMononucleosisMouth soresSexually transmitted diseasesTonsillitisTuberculosisSkin infectionsImmune or autoimmune disorders that can cause swollen lymph nodes include rheumatoid arthritis and HIV.Cancers that can often cause swollen lymph nodes include leukemia, Hodgkin's disease, or non-Hodgkin's lymphoma. However, many other cancers may also cause this problem.Which lymph nodes are swollen depends on the type of problem and the body parts involved. Identifying the location can help determine the possible cause.Swollen lymph nodes may also be caused by some medications (such phenytoin for seizures) or certain vaccinations (such as typhoid immunization).Home CareSoreness in lymph nodes usually disappears in a couple of days without treatment, but the nodes may not return to normal size for several weeks after the infection has cleared. Generally, if they are painful, it is because they swell rapidly in the early stages of fighting an infection.Call your health care provider ifCall your doctor if:Your lymph nodes do not get smaller after several weeks or continue to get larger.They are red and tender.They feel hard, irregular, or fixed in place.You have fever, night sweats, or unexplained weight loss.Any node in a child is larger than 1 centimeter (a little less than 1/2 inch) in diameter.What to expect at your health care provider's officeYour doctor will perform a physical examination, checking all of your palpable lymph nodes for size, texture, warmth, tenderness, and other features.Your doctor may ask the following medical history questions:Which nodes are affected?Is the swelling the same on both sides?When did the swelling begin?How long has it lasted (how many months or weeks)?Did it begin suddenly or did it develop gradually?Is the swelling increasing in size?Are the number of nodes that are swollen increasing?Are any of the swollen nodes painful or tender when you gently press on them?Is the skin over or around the nodes red?Have you had any other symptoms?The following diagnostic tests may be performed:Physical examBlood tests, including liver function tests, kidney function tests, and CBCwith differentialLymph node biopsyChest x-rayLiver-spleen scanReferencesPasternack MS, Swartz MN.
