What Proteins Are Measured?

Protein electrophoresis separates blood proteins into distinct fractions, including albumin, alpha-globulins, beta-globulins, and gamma-globulins. Each fraction may reflect underlying health conditions differently.

Why Is This Test Done?

Doctors may order this test to check for conditions like chronic kidney disease, liver disease, infections, or certain cancers. It can also help evaluate protein disorders or monitor treatment responses.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The serum (liquid part after clotting) is then analyzed to separate proteins by size and charge.

Common Conditions Monitored

Abnormal protein patterns can indicate conditions such as multiple myeloma (excess gamma-globulins), nephrotic syndrome (low albumin), or inflammatory diseases (elevated acute-phase proteins).

Reference range

INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A

Specimen: plasma

Inform your healthcare provider if you are taking blood thinners. No special preparation required.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical significance of protein electrophoresis includes diagnosing and managing conditions that alter protein synthesis, degradation, or transport in the body, such as hereditary disorders or metabolic diseases.

Short name

Serum Protein Electrophoresis

Frequently asked questions

What does a protein electrophoresis test tell me about my health?
It provides detailed information about the types and amounts of proteins in your blood, which can help identify issues like protein loss, protein overload, or specific protein abnormalities that may not be detected by simpler tests.
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 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 healthcare provider about any medications you’re taking, as some may affect protein levels.
