Mass concentration of a protein in serum (likely related to serum protein electrophoresis)

Published: August 9, 2026Updated: August 16, 2026

This test measures the total amount of protein in your serum, broken down by different protein groups (e.g., albumin, globulins). It helps identify imbalances that may indicate conditions like infections, inflammation, or certain blood disorders.

Why This Test Is Done

Your healthcare provider may order this test if they suspect conditions affecting protein levels, such as kidney disease, liver problems, or immune system disorders. It’s also used to monitor treatment progress for conditions like multiple myeloma or other protein-related diseases.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to fast for 8–12 hours before the test if your lab requires it. Bring any medications or questions to your appointment.

During the Test

A blood sample is drawn from a vein, typically in your arm. The blood is then processed to separate serum components for analysis. The results are compared to standard protein distribution patterns.

What the Results Mean

Results show the total protein mass and the relative proportions of different protein groups. Abnormal patterns may indicate conditions like hypoalbuminemia (low albumin), hyperglobulinemia (high globulins), or other systemic issues.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What could cause abnormal results?
Abnormal protein levels may be due to chronic diseases (e.g., kidney or liver disease), infections, autoimmune disorders, or certain cancers. Your doctor will interpret results in the context of your symptoms and medical history.
How long will I need to wait for results?
Results are typically available within 1–3 business days, depending on your lab. Your provider will discuss them with you during a follow-up visit.
Can I eat or drink before this test?
Check with your lab or provider for specific instructions, but fasting may be required for some protein electrophoresis tests. Avoid alcohol and excessive caffeine before testing.
