What is this test?

This is a qualitative urine test for alpha-1 globulin, a type of protein. It reports whether the protein is detected rather than providing a measured concentration.

Why might I need this test?

Your clinician may order this test as part of an evaluation of protein in the urine or urine protein electrophoresis. It may also be used to help interpret the pattern of proteins present in a urine sample.

How is the test performed?

A urine specimen is collected and examined in the laboratory for alpha-1 globulin. The result is generally reported as detected or not detected, and it may be compared with other findings from your urine tests.

How do I prepare for the test?

Follow your clinician's instructions for collecting the urine specimen. Often, this is a clean-catch sample collected at a specified time. Tell your clinician if you have a urinary tract infection, kidney disease, or are taking medicines that may affect your urine.

Reference range

Adult: 44-147 U/LN/A

Frequently asked questions

Does a detected result mean I have a kidney disease?
No. Detection of alpha-1 globulin alone does not diagnose kidney disease or establish its cause. Your clinician will consider your symptoms and the results of other urine and blood tests.
Is alpha-1 globulin the same as alpha-1 antitrypsin?
No. Alpha-1 globulin is a fraction of urine protein, while alpha-1 antitrypsin is a separate protein and a different laboratory test.
Why did my clinician order this test?
It was likely ordered to evaluate the pattern of protein in your urine, sometimes as part of urine protein electrophoresis. The result is most useful together with the rest of your laboratory evaluation.
