Ethanolamine-to-Creatinine Ratio, Urine
A urine test that measures ethanolamine relative to creatinine, helping account for differences in urine concentration.
["This ratio shows how much ethanolamine is being excreted relative to creatinine and is interpreted alongside the reason it was ordered."]

What is this test?
This test measures the amount of ethanolamine in urine relative to the amount of creatinine. The ratio can help interpret a urine ethanolamine result because creatinine is commonly used to account for how concentrated a urine sample is.
Why might I need this test?
A clinician may order it as part of a toxicology, metabolic, or other medical evaluation. The specific reason depends on your symptoms, medical history, medications, and any suspected exposures.
How is the test performed?
A urine specimen is tested for ethanolamine and creatinine, and the laboratory calculates the ethanolamine-to-creatinine ratio. The sample may be a routine, first-morning, or timed collection, depending on the instructions provided by the laboratory.
How do I prepare for the test?
No special diet or fasting is usually required unless your clinician specifically requests it. Follow the laboratory's urine-collection instructions carefully, including the collection time and whether the entire sample from a specified period is needed.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
An elevated ratio may reflect increased ethanolamine excretion, a more concentrated urine sample, or lower creatinine concentration; a lower ratio can reflect the opposite. The finding is not specific to one condition and should be interpreted with symptoms, medication and exposure history, and other laboratory results. Ask the ordering clinician what the result means in your individual situation.
