Hydrocodone, Body-Mass/Creatinine-Adjusted, Urine — Mass Concentration
A urine test that measures hydrocodone exposure, with results adjusted for body size and urine concentration when reported.
["A detectable result indicates hydrocodone exposure, but timing, dose, and clinical effects must be interpreted by your clinician."]

What is this test?
This test measures the amount of hydrocodone in urine. Hydrocodone is an opioid pain medicine. Some results are adjusted for body size and urine creatinine, which helps account for differences in urine concentration.
Why might I need this test?
A clinician may order this test to assess recent hydrocodone exposure, monitor use of prescribed opioid medication, or evaluate a possible drug-related concern. It may also be included in certain drug-screening programs.
How is the test performed?
A urine sample is collected and analyzed by the laboratory to determine the concentration of hydrocodone. The report may include body-mass and creatinine adjustments to help make the result more comparable.
How do I prepare for the test?
Follow the collection instructions provided by the laboratory or clinician. Tell the healthcare provider about all medicines and supplements you have taken, including hydrocodone products and other opioids. Do not stop prescribed medication unless your clinician instructs you to do so.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Detecting hydrocodone in urine generally indicates recent exposure, but it does not by itself establish the exact dose, time of use, or level of impairment. A result that is higher than expected for the clinical situation may reflect recent use, a larger dose, or differences in urine concentration. A negative result cannot completely exclude exposure because hydrocodone may no longer be detectable.
Short name
Urine hydrocodone concentration
