Alcohol, Urine, Quantitative
Also known as: CDCO ETOH
Use
This test is used to quantitatively determine alcohol concentration in urine samples, which can be useful in assessing ethanol exposure. However, it has limited utility for acute ethanol exposure but can help monitor ethanol exposure up to several days post-consumption using Ethyl Glucuronide screening. It is not suitable for forensic purposes but is used for clinical analysis.
Special Instructions
Not provided.
Limitations
The test may not detect expected drug(s) or metabolite(s) if sample collection does not align with the drug administration timeline. Limitations include poor drug absorption, dilution, or adulteration of urine. The test's detection capability is constrained by a positive cutoff of 5 mg/dL, and results depend on reaching or exceeding this threshold.
