What This Test Measures

The test analyzes the concentration and distribution of different protein classes (e.g., albumin, globulins, fibrinogen) in your blood. Results may show shifts in protein bands that can indicate underlying health issues.

Why It’s Ordered

Your healthcare provider may order this test to assess conditions like chronic kidney disease, liver disease, or certain cancers. Trends over time help track disease progression or response to treatment.

Sample Preparation

A blood sample is drawn, and the serum or plasma is separated for testing. Some labs may require fasting or specific timing to ensure accurate results.

Common Conditions Monitored

This test helps identify abnormalities in protein levels, such as low albumin (common in kidney or liver disease) or abnormal globulin patterns (possible in autoimmune disorders or infections).

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a ‘trend’ mean in this test?
A trend refers to how your protein levels or patterns change over time. For example, a consistent decline in albumin might indicate worsening kidney or liver function.
How long does it take to get results?
Results are typically available within 24 to 48 hours, depending on lab processing times and whether additional testing is needed.
Can I eat or drink before this test?
Most blood tests, including this one, do not require fasting. However, always follow your healthcare provider’s instructions for specific instructions.
