What is this test?

This test measures the concentration of alpha-1 globulin, a small protein that can pass through the kidneys into the urine. It may be part of a urine protein evaluation or protein electrophoresis panel.

Why might I need this test?

Your clinician may order this test to investigate increased protein in the urine, assess kidney function, or help interpret the pattern of proteins present. It is generally considered together with urine albumin, total protein, creatinine, and other clinical findings.

How is the test performed?

A urine sample is collected and analyzed in the laboratory to determine the amount of alpha-1 globulin. The result may be reported as a mass concentration or compared with a urine protein measurement, depending on the laboratory method.

How do I prepare for the test?

Follow your clinician's instructions about the type and collection period for the urine sample. Be sure to state any urine collection period and report medicines, supplements, supplements, or health conditions that could affect the result.

Frequently asked questions

Does a high result mean I have kidney disease?
Not necessarily. Increased urine alpha-1 globulin can occur with several conditions, so your clinician will interpret it alongside other urine and kidney tests.
What type of urine sample is needed?
The required sample may be a single urine specimen or urine collected over a specific period. Follow the collection instructions provided by your clinician or laboratory.
What other tests are often reviewed with this result?
Clinicians commonly consider urine albumin, total urine protein, urine creatinine, and blood tests that assess kidney function. The pattern of the results is usually more useful than this test alone.
