What is this test?

This test uses urine protein electrophoresis to measure alpha-2 globulin, a group of proteins, in a 24-hour urine collection. It estimates the amount of this protein fraction leaving the body each day.

Why might I need this test?

It may be ordered as part of a urine protein evaluation to help assess kidney function or identify unusual patterns of protein excretion. It is generally interpreted alongside the rest of the urine protein electrophoresis and other clinical findings.

How is the test performed?

You collect urine for a full 24 hours according to the laboratory’s instructions. The laboratory separates urine proteins by electrophoresis and calculates the alpha-2 globulin amount using the measured urine volume and concentration.

How do I prepare for the test?

Follow the laboratory’s 24-hour collection instructions carefully, including the start and end times and whether the container should be refrigerated. Record the total urine volume and bring the collection container to the laboratory as directed.

Reference range

Adult: 44-147 U/LN/A

Frequently asked questions

Is this the same as a routine 24-hour urine protein test?
Not exactly. This test specifically measures the alpha-2 globulin fraction using electrophoresis, while a routine 24-hour urine protein test measures total protein.
Do I need to fast for this test?
Fasting is usually not required. Follow any specific instructions provided by your healthcare professional or laboratory.
What if I miss part of the 24-hour urine collection?
Tell the laboratory, because an incomplete collection can make the calculated result less accurate. You may need to repeat the collection.
