Lymph Node Fluid Protein Electrophoresis (Manual)
This test measures the types and amounts of proteins in fluid collected from a lymph node biopsy, often used to diagnose conditions like lymphoma or infections.
["Protein electrophoresis helps identify abnormal protein patterns that may signal cancer or immune system issues."]

Why This Test Is Done
Your doctor may order this test if you have symptoms like swollen lymph nodes, unexplained weight loss, fever, or night sweats. It helps determine whether the fluid contains abnormal cells, which could indicate lymphoma, infections, or other conditions affecting your immune system.
How the Test Is Performed
A small amount of fluid is collected from a lymph node during a biopsy. The fluid is then processed and analyzed using electrophoresis, a technique that separates proteins based on size and charge. This allows for detailed examination of protein composition.
What to Expect Before the Test
No special preparation is typically needed, but you may be asked to avoid certain medications or foods that could interfere with results. Your doctor will explain any restrictions and provide instructions for the day of the procedure.
What to Expect During the Test
The procedure involves a local anesthetic to numb the area, followed by a small incision to collect fluid. The fluid is then sent to a lab for analysis. The process usually takes a few minutes and may cause mild discomfort.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal protein patterns detected in lymph fluid can help diagnose conditions such as lymphoma, infections (like tuberculosis), or other immune-related disorders. For example, certain proteins may indicate the presence of malignant cells, while others may suggest inflammation or infection.
