What This Test Measures

The bromocresol green dye binds to different proteins in your serum, allowing separation via electrophoresis. This helps distinguish between albumin (the primary protein in blood) and globulins (proteins like antibodies).

Why It’s Done

Your healthcare provider may order this test to diagnose or monitor conditions affecting protein levels, such as liver disease, kidney disease, or certain immune disorders.

Common Uses

This test is particularly useful for identifying abnormal protein patterns that may indicate conditions like hypoalbuminemia (low albumin) or dysproteinemias (unusual protein abnormalities).

Sample Collection

A blood sample is drawn from a vein, typically in your arm. The serum portion is separated and analyzed for protein distribution.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance

Short name

BCG Protein Electrophoresis

Frequently asked questions

How long does it take to get results from this test?
Results are usually available within 24 to 48 hours, depending on lab processing times and your healthcare provider’s workflow.
Can I eat or drink anything before this test?
No special preparation is needed for this test. However, inform your provider if you’re on certain medications that might affect protein levels.
What does an abnormal result mean?
An abnormal result may suggest liver or kidney issues, infections, or other conditions affecting protein synthesis or breakdown. Your provider will discuss findings with you in detail.
