What is this test?

Alpha-2 globulin is a group of proteins that can be measured in dialysis fluid. This test uses electrophoresis to determine the proportion of these proteins in the sample.

Why might I need this test?

This test may be used to evaluate the protein composition of dialysis fluid. It is interpreted along with your dialysis treatment, symptoms, laboratory results, and other relevant findings.

How is the test performed?

A small sample of dialysis fluid is collected according to your dialysis team's protocol. The laboratory separates the proteins by electrophoresis and reports the alpha-2 globulin fraction.

How do I prepare for the test?

No special preparation is usually needed. Follow the collection instructions provided by your dialysis team, as timing and handling may vary by facility.

Reference range

Adult: 44-147 U/LN/A

Specimen: serum

No special preparation required. Avoid fatty meals before the test if possible.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

An increased or decreased alpha-2 globulin fraction can indicate a change in the protein composition of the dialysis fluid. The meaning depends on the type of dialysis, collection timing, and other laboratory findings, so this result should not be used alone to diagnose a condition.

Short name

Alpha-2 globulin in dialysis fluid

Frequently asked questions

Do I need to fast for this test?
Fasting is generally not required, but your dialysis team may provide specific collection instructions for your treatment schedule.
Does this test measure my blood protein levels?
No. This test measures alpha-2 globulin in dialysis fluid, not directly in blood. Blood protein tests are different tests.
Can one result diagnose a health condition?
No. The result must be interpreted with your overall health, dialysis details, trends, and other laboratory tests because changes are not specific to one condition.
