If you're experiencing swollen lymph nodes, several blood tests can help identify the underlying cause. Swollen lymph nodes can be a sign of various conditions, including infections, autoimmune diseases, and malignancies. Here are some common blood tests that may be ordered:
1. **Complete Blood Count (CBC):** This test measures various components of your blood, including red blood cells, white blood cells, and platelets. An elevated white blood cell count may indicate an infection or inflammation.
2. **Erythrocyte Sedimentation Rate (ESR):** This test detects inflammation in the body. A high ESR can indicate the presence of an inflammatory process, which may be due to infection, autoimmune disease, or certain cancers.
3. **C-Reactive Protein (CRP):** Similar to ESR, this test measures inflammation in the body. Elevated levels of CRP can signify infection or other inflammatory conditions.
4. **Liver Function Tests:** These tests can help assess the health of the liver, which can be affected by infections (like viral hepatitis) or other systemic illnesses.
5. **HIV Test:** Since swollen lymph nodes can be a sign of HIV infection, testing for HIV may be considered based on your risk factors and symptoms.
6. **Monospot Test:** This test is specifically used to detect infectious mononucleosis, commonly caused by Epstein-Barr virus (EBV), which can result in swollen lymph nodes.
7. **Blood cultures:** If a bacterial infection is suspected, blood cultures may be drawn to identify any bacteria in the bloodstream.
8. **Specific Antibody Tests:** In some cases, tests for specific infections (like cytomegalovirus, toxoplasmosis, or other viral pathogens) may be ordered based on symptoms and exposure history.
9. **Tumor Markers (if malignancy is suspected):** Depending on symptoms and clinical suspicion, specific tumor markers may be tested.
If you have swollen lymph nodes, it’s important to see a healthcare provider for a comprehensive evaluation to determine the need for further investigation and appropriate management.
