What This Test Measures

Electrophoresis separates blood proteins based on size and electrical charge. The test looks at five main protein bands: albumin, alpha-1, alpha-2, beta, and gamma globulins. Abnormal patterns may indicate conditions like infections, immune disorders, or metabolic issues.

Why It’s Ordered

Your doctor may recommend this test if you have symptoms like unexplained weight loss, fatigue, swollen glands, or signs of organ dysfunction. It’s also used as part of routine screening for certain blood disorders or to monitor treatment progress.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The blood is then processed to separate serum or plasma for testing. No special preparation is needed, but fasting may be advised depending on your doctor’s instructions.

What to Expect After Testing

Results are typically ready within 24–48 hours. You’ll discuss them with your healthcare provider, who may recommend follow-up tests or treatments based on the findings.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How long does it take to get results?
Results are usually available within 24–48 hours, but timing can vary. Your doctor will contact you once they’re ready.
Can I eat or drink before this test?
No special diet is required, but check with your doctor if they’ve given specific instructions for fasting or timing.
What does a ‘qualitative’ result mean?
A qualitative test provides a yes/no or pattern-based result rather than a specific numeric value. Your doctor will explain what the pattern means in your context.
