Methylone and Creatinine, Urine
A urine test that checks for methylone, a stimulant sometimes called a “designer drug,” and measures creatinine to help assess urine concentration.
["Detecting methylone in urine may indicate recent exposure, while urine creatinine helps determine whether the sample is too dilute for reliable interpretation."]

What is this test?
This test examines a urine sample for methylone, an illegal stimulant chemically related to MDMA (ecstasy). It also measures urine creatinine, which reflects how concentrated the urine is and can help determine whether a low drug result may be affected by dilution.
Why might I need this test?
Methylone testing may be requested when recent drug use is suspected, during emergency evaluation, or for employment, school, legal, or substance-use monitoring. It is not the same as a methadone test, and its availability may vary by laboratory.
How is the test performed?
A urine specimen is collected and analyzed by the laboratory. Screening methods may not detect methylone reliably, so a specific laboratory method or confirmatory testing may be needed. Creatinine is measured to help evaluate the concentration of the specimen.
How do I prepare for the test?
Follow the collection instructions provided by the laboratory or clinician, and do not drink excessive amounts of water beforehand. Tell the clinician about prescription medicines, over-the-counter products, supplements, and other drugs you have recently used, because these can affect interpretation or the testing method.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A detectable methylone result indicates that methylone was present in the urine and may be consistent with recent use. A negative result does not completely exclude exposure because the detection window depends on the dose, timing, urine concentration, and testing method. Urine creatinine helps show whether a dilute sample may have affected the result. A positive result should be interpreted by a healthcare professional, especially with confirmatory testing.
