What This Test Measures

Protein electrophoresis separates blood proteins into different fractions (e.g., albumin, globulins) using an electric field. Bromocresol green dye helps visualize these fractions, revealing any unusual distributions that might indicate conditions like monoclonal gammopathy or liver/kidney issues.

Why It’s Ordered

Your healthcare provider may order this test if you have symptoms like unexplained weight loss, fatigue, swollen lymph nodes, or signs of organ dysfunction. It’s also used as part of screening for conditions like multiple myeloma, amyloidosis, or chronic liver disease.

Sample Collection and Preparation

A blood sample is drawn from a vein, typically in your arm. The serum or plasma is then processed and mixed with bromocresol green dye before being analyzed in an electrophoresis machine.

Interpreting Results

Results are qualitative, meaning they describe patterns rather than specific numeric values. Abnormal bands or shifts in protein distribution may signal potential issues that require further testing or evaluation by a specialist.

Reference range

Adult males: 8-61 U/L; Adult females: 5-36 U/LN/A

Specimen: serum

No special preparation required. Avoid fatty meals before the test if possible.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a ‘qualitative’ result mean?
A qualitative result describes whether certain protein patterns are present or absent, rather than providing exact measurements. Your doctor will interpret these patterns in the context of your symptoms and medical history.
Can this test detect early-stage diseases?
While it can identify some conditions, this test may not detect early-stage diseases alone. It’s often used alongside other tests for a more complete picture.
How long does it take to get results?
Results are typically available within 24 to 48 hours, depending on lab processing times and your healthcare provider’s workflow.
