What This Test Measures

Protein electrophoresis separates blood proteins into fractions (e.g., albumin, globulins) based on size and charge. Bromocresol green is used to stain specific protein groups, helping detect variations in concentration or distribution that may indicate conditions like multiple myeloma, nephrotic syndrome, or other protein disorders.

Why It’s Done

Your doctor may order this test if you have symptoms like unexplained weight loss, swelling, frequent infections, or signs of kidney problems. It’s also used in screening or monitoring conditions affecting protein balance in the body.

Common Uses and Indications

This qualitative test is often used as a screening tool to detect abnormal protein patterns that might not be visible in routine blood tests. It helps diagnose conditions where specific protein fractions are elevated or depleted.

What to Expect Before the Test

No special preparation is needed, but you may be asked to fast for 8–12 hours before drawing blood if your doctor specifies. Wear comfortable clothing and plan to rest during the procedure.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal results may indicate conditions such as multiple myeloma (excess plasma cells), nephrotic syndrome (kidney-related protein loss), or other systemic protein disorders. Changes in protein bands can also signal chronic inflammation, liver disease, or autoimmune disorders.

Short name

Protein Electrophoresis (Bromocresol Green)

Frequently asked questions

What does a ‘positive’ or abnormal result mean?
An abnormal result means your protein pattern differs from what’s expected. This could signal a hidden condition requiring further testing, like a bone marrow biopsy or additional bloodwork to pinpoint the cause.
Will this test show early signs of kidney disease?
Yes, protein electrophoresis can detect early signs of kidney disease by revealing unusual protein bands or patterns, such as high levels of light chains (Bence Jones proteins) in multiple myeloma or albumin loss in nephrotic syndrome.
How often should I get this test?
Your doctor will determine frequency based on your health status. If you have a known condition affecting proteins, they may recommend regular monitoring; otherwise, it’s typically ordered as needed for symptoms or diagnostic purposes.
