Test ID: VLTU    
Volatile Screen, Urine

Useful For Suggests clinical disorders or settings where the test may be helpful

Detecting the presence of acetone, methanol, isopropanol, or ethanol in urine with subsequent quantitation

Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Urine provides a medium for easy screening.

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

METHANOL

Not detected (Positive results are quantitated.)

Cutoff concentration: 10 mg/dL

Toxic concentration: > or =10 mg/dL

 

ETHANOL

Not detected (Positive results are quantitated.)

Cutoff concentration: 10 mg/dL

 

ISOPROPANOL

Not detected (Positive results are quantitated.)

Cutoff concentration: 10 mg/dL

Toxic concentration: > or =10 mg/dL

 

ACETONE

Not detected (Positive results are quantitated.)

Cutoff concentration: 10 mg/dL

Toxic concentration: > or =10 mg/dL

Interpretation Provides information to assist in interpretation of the test results

Methanol

-Not detected (positive results are quantitated)

 

Ethanol

-Not detected (positive results are quantitated)

 

Isopropanol

-Not detected (positive results are quantitated)

 

Acetone

-Not detected (positive results are quantitated)

Cautions Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Quantitation of acetone, methanol, isopropanol, or ethanol in urine correlates poorly with degree of intoxication.

 

For best clinical correlation VLTS / Volatile Screen, Serum or VLTB / Volatile Screen, Blood is suggested.

Clinical Reference Provides recommendations for further in-depth reading of a clinical nature
