What is this test?
This test measures ethanolamine, a naturally occurring compound involved in lipid metabolism, relative to creatinine in a 24-hour urine sample. Creatinine is used as a reference for how concentrated the urine is.
Why might I need this test?
This specialized test may be ordered when a clinician is evaluating a suspected metabolic or inherited disorder. It is generally interpreted together with symptoms, other laboratory results, and the type of 24-hour urine collection.
How is the test performed?
All urine produced during a full 24-hour period is collected in a labeled container and sent to the laboratory for measurement. The laboratory calculates the ethanolamine-to-creatinine ratio and may also report the total amount of each substance collected.
How do I prepare for the test?
Follow the collection instructions provided by the laboratory, including the exact start time, end time, container, and any preservative. Collect all urine during the 24-hour period without spilling it, and tell the care team about medications, supplements, or major dietary changes.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A higher or lower ratio may reflect increased or decreased ethanolamine excretion, differences in urine concentration, or a metabolic condition affecting ethanolamine metabolism. Because this is a specialized test, an abnormal result should be interpreted by the ordering clinician using the complete laboratory report and clinical context.
