Serum/plasma concentration of albumin (qualitative or semi-quantitative protein electrophoresis)

What Is Albumin Electrophoresis Used For?

Albumin electrophoresis measures the concentration and distribution of proteins in your serum or plasma using gel electrophoresis. This method separates proteins based on size and charge, allowing for qualitative or semi-quantitative analysis of albumin among other proteins. It’s particularly useful when other protein tests (like total protein) are inconclusive or when specific protein patterns need further investigation.

How Is This Test Performed?

A blood sample is drawn, and the serum or plasma is applied to a gel. An electric current is applied, causing proteins to migrate at different speeds. The resulting pattern is analyzed to identify albumin levels and any abnormal protein bands.

Common Conditions Monitored

This test may be used to diagnose or monitor conditions such as nephrotic syndrome (kidney disease causing protein loss), liver disease, multiple myeloma (cancer of plasma cells), or other protein-related disorders. It can also help assess nutritional status or response to treatment.

Preparation and Sample Requirements

No special preparation is needed, but avoid strenuous activity 24 hours before testing. The sample is typically collected from a vein, and results may take several days to process, depending on lab workflow.
