What is this test?
This test measures phenol and creatinine in urine, stool, or both. Creatinine may be reported as a separate measurement or used to compare phenol with creatinine, depending on the laboratory's test method.
Why might I need this test?
Phenol testing may be used when there is concern about exposure to phenol or related chemicals, such as in the workplace. Creatinine may be included to help account for differences in urine concentration or to provide additional information about kidney function.
How is the test performed?
A urine sample and/or a stool sample is collected and analyzed by the laboratory. The results may include the amount of phenol, the amount of creatinine, and a calculated comparison between them.
How do I prepare for the test?
Follow the collection instructions provided by the laboratory, including any timing, container, and storage requirements. Tell your clinician about workplace chemical exposure, recent illness, medications, and supplements; do not stop prescribed medicines unless instructed.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
An elevated phenol result may indicate exposure to phenol or another source of phenol-containing chemicals, although diet, medications, and specimen handling can also affect it. Creatinine results may vary with hydration and kidney function, and stool creatinine may have a different purpose from urine creatinine. Your healthcare professional should interpret the results together with your exposure history, symptoms, and other tests.
