What This Test Measures

Electrophoresis separates blood proteins based on size and charge. Bromocresol green dye binds to albumin, allowing for visual differentiation between albumin and globulin fractions. This helps identify shifts in protein composition that may indicate liver disease, malnutrition, or other conditions.

Why It’s Ordered

Your healthcare provider may order this test to evaluate protein abnormalities, such as low albumin levels (which can signal liver or kidney issues) or abnormal globulin patterns (linked to immune system disorders or chronic inflammation).

Common Conditions Monitored

Conditions like cirrhosis, chronic liver disease, nephrotic syndrome, or certain autoimmune disorders may show altered protein profiles on this test.

Sample Collection

A blood sample is drawn from a vein, typically in your arm. The sample is processed to separate serum or plasma for testing.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How does bromocresol green electrophoresis differ from other protein tests like albumin or globulin measurements?
This test provides a broader view of protein distribution by visually separating and quantifying albumin and globulin fractions, unlike standalone albumin or globulin tests that measure specific proteins only.
What does a high or low protein result mean in this test?
Results may indicate liver dysfunction (low albumin), immune disorders (elevated globulins), or malnutrition (reduced total protein). Always discuss results with your provider for interpretation.
Can this test be done at home?
No, this test requires a lab sample collected by a healthcare professional. Results are typically reported within 1–3 business days.
