What This Test Measures

Electrophoresis separates proteins in your serum or plasma based on size and charge. The bromocresol green dye binds to specific protein fractions, allowing for visual or quantitative analysis of their relative concentrations. This process helps identify shifts in protein patterns that may indicate underlying health issues.

Why It’s Done

Your healthcare provider may order this test to evaluate conditions like multiple myeloma, liver disease, or other disorders that alter protein composition in your blood.

Sample Collection and Preparation

A blood sample is drawn from a vein, typically in the arm. The blood is then separated into serum or plasma for testing. This test does not require fasting unless specified by your provider.

Common Conditions Monitored

This test can help detect abnormal protein patterns linked to conditions such as nephrotic syndrome, certain cancers, or metabolic disorders. It may also be used to monitor treatment responses in patients with known protein-related diseases.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How long will it take to get my results?
Results are usually available within 24 to 48 hours, depending on your lab’s processing schedule. Your healthcare provider will discuss the findings with you during your follow-up visit.
Can I eat or drink before this test?
No special preparation is needed for this test, but always follow your provider’s instructions. Avoid alcohol or certain medications that may affect protein levels if directed.
What does a ‘normal’ result mean?
A ‘normal’ result does not mean there is no underlying issue—it simply indicates typical protein distribution. Abnormal patterns may require further testing or evaluation by your healthcare provider.
