JWH-073 Butanol/Creatinine Ratio, Urine

Published: August 9, 2026Updated: August 16, 2026

Measures a JWH-073-related compound in urine relative to creatinine, helping assess exposure to the synthetic cannabinoid JWH-073.

Quick summary

What is this test?

This urine test measures a JWH-073-related compound, often referred to as JWH-073 butanol, and compares it with the urine creatinine level. Creatinine is used to help account for differences in urine concentration.

Why might I need this test?

The test may be ordered when exposure to JWH-073, a synthetic cannabinoid sometimes called a Spice product, is suspected. It may also be used for drug monitoring in clinical, workplace, school, legal, or other appropriate settings.

How is the test performed?

A urine specimen is collected and analyzed in a laboratory. The laboratory measures the JWH-073-related compound and creatinine and may report their ratio to help adjust for urine concentration.

How do I prepare for the test?

No special preparation is usually required unless your healthcare professional provides specific instructions. Collect the urine sample in the container and at the time requested by the laboratory.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a positive result mean?
It indicates that a JWH-073-related compound was detected in the urine. It does not by itself prove when the exposure occurred or whether the person was impaired.
Why is the result compared with creatinine?
Urine concentration can vary substantially between samples. Comparing the test substance with creatinine helps provide a more meaningful measure when urine is very dilute or concentrated.
Can this test determine the effects of JWH-073?
No. The laboratory result indicates exposure but cannot reliably measure intoxication, impairment, or the severity of possible effects.
