Bromocresol Green Protein Electrophoresis (Serum)

Published: August 9, 2026Updated: August 16, 2026

This test measures protein distribution in your blood using a technique called electrophoresis with the bromocresol green dye. It helps assess the pattern of proteins, which can indicate conditions affecting protein synthesis, breakdown, or kidney function.

What This Test Measures

Electrophoresis separates proteins in your serum based on size and charge. Bromocresol green binds to certain proteins, allowing for visual differentiation of protein bands. This helps identify abnormal protein distributions, such as those seen in conditions like nephrotic syndrome or multiple myeloma.

Why It’s Ordered

Your doctor may order this test if they suspect kidney disease, liver problems, or other conditions that alter protein levels. It can also be used to monitor treatment responses or diagnose conditions like amyloidosis or dysproteinemias.

Common Uses and Indications

This test is particularly useful for detecting changes in protein fractions that might not be visible with standard blood tests. It helps identify specific protein abnormalities that could signal underlying health issues.

Clinical Significance

Abnormal results may suggest conditions like nephrotic syndrome (where large amounts of protein leak into urine), multiple myeloma (a cancer of plasma cells), or other disorders affecting protein metabolism.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How long does it take to get results from this test?
Results are typically available within 24 to 48 hours, depending on lab processing times. Your doctor will discuss the findings with you during your follow-up visit.
What does a normal result mean?
A normal result indicates that your protein distribution in serum appears within expected ranges, suggesting no obvious abnormalities in protein synthesis, breakdown, or kidney function. However, doctors may still order it for monitoring or research purposes.
Can this test be done at home?
No, this test requires a blood sample drawn in a clinical setting. It is performed in a laboratory using specialized equipment and techniques.
