What is this test?

This test measures the amount of suberate, an organic acid, in urine compared with the amount of creatinine. Creatinine is used as a reference because its amount in urine varies with urine concentration, while the suberate-to-creatinine ratio can help account for differences in how concentrated a urine sample is.

Why might I need this test?

This test may be ordered as part of an evaluation of unusual metabolic findings or symptoms. It is not widely used on its own and is generally interpreted alongside other laboratory tests and clinical information.

How is the test performed?

A urine sample is collected and analyzed in the laboratory using a turbidimetric method. The laboratory reports the amount of suberate relative to the amount of creatinine in the sample.

How do I prepare for the test?

Follow your laboratory's collection instructions, including whether to provide a first-morning or random urine sample. Fasting is usually unnecessary, but you should not make major dietary changes specifically for this test unless your clinician advises you to do so.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does the suberate/creatinine ratio show?
It shows the amount of suberate in urine relative to creatinine. Creatinine helps adjust the result for variations in urine concentration.
Is this a common blood test?
No. This is a urine test and is generally used only in selected evaluations, often as part of a broader metabolic assessment.
Do I need to fast before the test?
Fasting is usually not required, but collection timing and any dietary restrictions should follow the instructions provided by the laboratory or ordering clinician.
