What This Test Measures

Electrophoresis divides blood components into distinct bands, allowing for the identification of proteins like albumin, globulins, and other substances. This method helps assess conditions affecting protein balance, such as infections, inflammation, or genetic disorders.

Common Clinical Uses

Doctors may use this test to diagnose or monitor conditions like multiple myeloma, amyloidosis, or chronic liver disease. It can also help evaluate protein abnormalities in conditions like nephrotic syndrome or certain autoimmune disorders.

Sample Preparation

A small blood sample is drawn from your arm. The blood is processed to separate proteins, and the results are analyzed to create a profile of your blood proteins.

Preparation for the Test

No special preparation is needed. However, inform your healthcare provider about any medications you’re taking, as some may affect protein levels.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Why might I need this test?
Your doctor may recommend this test if they suspect conditions affecting protein balance, such as certain cancers, liver disease, or inherited protein disorders. It can also be part of routine monitoring for patients with known protein-related conditions.
How long will results take to return?
Results are typically available within a few days to a week, depending on lab processing times. Your healthcare provider will discuss the findings with you during your follow-up visit.
Can I eat or drink before this test?
No special diet or fasting is required for this test. However, if you have any questions about timing your blood draw around meals, ask your healthcare provider.
