Bromocresol Green Protein Electrophoresis (Serum)
This test measures the distribution of proteins in your blood using an electrophoresis method with bromocresol green dye. It helps assess protein patterns, often used to evaluate conditions affecting protein synthesis or breakdown.
["This test helps diagnose and monitor conditions related to abnormal protein levels in your blood."]

What This Test Measures
Electrophoresis separates proteins in your serum based on size and charge. Bromocresol green dye binds to specific protein fractions, allowing for visual differentiation of albumin, alpha-globulins, beta-globulins, and globulins. This pattern can reveal imbalances linked to diseases like liver disease, kidney disease, or inflammatory conditions.
Why It’s Ordered
Your healthcare provider may order this test if you have symptoms like unexplained weight loss, swelling, fatigue, or if tests suggest abnormal protein levels. It’s also used to monitor conditions like multiple myeloma, nephrotic syndrome, or chronic liver disease.
Common Conditions Monitored
Abnormal protein patterns detected by this test can indicate conditions affecting protein metabolism, such as liver dysfunction, kidney disease, or certain cancers. For example, low albumin may signal liver or kidney problems, while unusual globulin patterns could hint at immune system disorders.
What to Expect Before the Test
No special preparation is needed. You may have a blood draw from a vein in your arm. If you’re on blood thinners or have a history of bleeding, let your provider know.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test provides insights into the overall protein profile in your blood, which can help diagnose or guide treatment for conditions like protein-losing syndromes, chronic inflammation, or metabolic disorders. It’s particularly useful when other tests (like albumin or globulin levels) show irregularities.
