Serum or plasma protein electrophoresis with bromocresol purple staining

What This Test Measures

Protein electrophoresis separates blood proteins into fractions based on their size and electrical charge. Bromocresol purple staining highlights specific protein bands, helping to detect variations in protein concentration across different regions of the electrophoresis gel.

Common Uses and Conditions Monitored

This test is commonly used to diagnose or monitor conditions like multiple myeloma, certain types of kidney disease (e.g., nephrotic syndrome), liver diseases, and hereditary protein disorders. It may also be used as part of a general health evaluation or to assess protein metabolism.

Sample Collection and Preparation

Blood is drawn from a vein, typically in your arm. The sample is then processed to separate serum or plasma, which is sent to the lab for electrophoresis. No special preparation is needed, but fasting may be advised depending on the clinical context.

Interpreting Results

Results are interpreted by comparing the protein bands to reference patterns. Abnormal bands or shifts may indicate elevated or reduced levels of specific proteins, which can help guide diagnosis and treatment planning.
