Second most predominant biomarker in blood drawn for general metabolic or inflammatory screening (qualitative protein electrophoresis)

What This Test Measures

The test uses a technique called electrophoresis to separate proteins in your blood by size and charge. This creates a pattern of bands that represent various proteins, including albumin, globulins, and other components. The second most prominent band (often globulins) is analyzed to detect shifts in protein distribution that may indicate disease.

Why It’s Done

Your healthcare provider may order this test if you have symptoms like fatigue, swelling, or unexplained weight changes, or if they suspect conditions like chronic liver disease, multiple myeloma, or other protein-related disorders. It’s also sometimes used as part of routine monitoring for certain chronic illnesses.

Sample Collection and Preparation

A blood sample is drawn from a vein, typically in your arm. The blood is then processed to separate the serum or plasma, where proteins are analyzed. The test does not require fasting unless specified by your doctor.

Common Conditions Monitored

This test helps diagnose or evaluate conditions such as liver disease (e.g., cirrhosis), kidney disease, infections, or autoimmune disorders. Abnormal patterns may also suggest conditions like myeloma or other protein disorders.
