The protein electrophoresis test in serum is a laboratory test used to identify and evaluate the different protein components in the blood serum. The main purpose of this test is to separate proteins based on their size and electrical charge, allowing doctors to analyze different protein patterns. The results provide important information about albumin and globulin levels, which can indicate health conditions such as immune disorders, infections, or certain types of cancer. This test is a vital tool for diagnosing and monitoring diseases like multiple myeloma or hepatitis. The test is performed by drawing a blood sample, after which the proteins are separated using an electric field. The results are carefully analyzed in the context of clinical symptoms and the patient’s medical history, helping doctors make evidence-based treatment decisions.
