Erythritol and Creatinine — Urine, Serum, or Stool
This test measures erythritol, a sugar alcohol, and creatinine in urine, serum, or stool as specified by the order.
["The results can help a clinician evaluate erythritol metabolism or related metabolic concerns, but interpretation depends on the specimen and clinical context."]

What is this test?
This test measures the amount of erythritol, a sugar alcohol naturally present in the body and obtained from some foods, in urine, serum, or stool. It may also measure creatinine, which can provide context for kidney function or the concentration of a urine sample.
Why might I need this test?
A clinician may order this test when evaluating an unusual sugar metabolism concern, a possible inherited metabolic disorder, or erythritol exposure and elimination. The reason for testing and the most useful specimen depend on the clinical situation.
How is the test performed?
A blood, urine, or stool sample is collected according to the instructions provided with the order. The laboratory analyzes the selected specimen for erythritol and, when appropriate, creatinine using a validated testing method.
How do I prepare for the test?
Follow the specimen-specific collection instructions from your healthcare provider. If a timed urine collection is requested, record the start and finish times and collect all urine during that period; do not fast unless you are specifically told to do so.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
An elevated erythritol result may reflect recent dietary intake, changes in metabolism, reduced kidney clearance, or a less common metabolic condition. Results can also vary with the specimen type, collection timing, and laboratory method, so they should be interpreted alongside symptoms, diet, medications, and other tests. Creatinine may help provide context for kidney function or urine concentration, but an abnormal result alone is not diagnostic.
Short name
