What Proteins Are Measured?

Serum protein electrophoresis separates proteins into five main bands: albumin, alpha-1 globulins, alpha-2 globulins, beta globulins, and gamma globulins. These bands reflect the balance of different protein types in your blood, which can change with health conditions.

Why Is This Test Done?

Doctors may order this test to investigate symptoms like fatigue, unexplained weight loss, or swollen lymph nodes. It’s also used to monitor conditions like multiple myeloma, lymphoma, or liver/kidney disease by checking for abnormal protein spikes or shifts.

Sample Collection and Preparation

Blood is drawn from a vein, usually in your arm. The blood is then processed to separate serum (the liquid part after clotting) for testing. No special preparation is needed, but fasting may be advised depending on your doctor’s instructions.

What Results Mean?

Results show the relative amounts of each protein band. Abnormal patterns (e.g., extra bands, missing bands, or skewed ratios) may signal underlying health issues. Your doctor will interpret results in the context of your symptoms and medical history.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How long does it take to get results from this test?
Results are typically available within 24 to 48 hours, depending on lab processing times. Your doctor will contact you once results are ready.
Can I eat or drink before this test?
No specific diet is required, but always follow your doctor’s instructions. If fasting is advised, avoid food or liquids (except water) for a set period before the test.
What if my results show an abnormal protein pattern?
If results are abnormal, your doctor may recommend further testing or treatments, such as bone marrow biopsy, additional blood tests, or monitoring for conditions like multiple myeloma or autoimmune disorders.
