What This Test Measures

Electrophoresis separates blood proteins based on size and charge, allowing for the identification of different protein fractions. Bromocresol green dye binds to albumin and globulins, helping distinguish their relative concentrations.

How the Test Works

A small blood sample is drawn and placed in a gel medium. An electric current is applied, causing proteins to migrate toward the opposite charge. The dye highlights protein bands, revealing their distribution.

Common Uses

This test is often used to diagnose conditions like cirrhosis, nephrotic syndrome, or multiple myeloma, where abnormal protein patterns may appear in the blood.

Sample Collection

A vein in your arm is cleaned and a small needle is used to draw blood into a tube. The sample is then sent to the lab for processing.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
