HelpTest ID VLTU Volatile Screen, Urine
Useful For
Detecting the presence of acetone, methanol, isopropanol, or ethanol in urine with subsequent quantitation
Method Name
Headspace Gas Chromatography-Flame Ionization Detector
(HSGC-FID)
Includes methanol, ethanol, isopropanol, and acetone.
Reporting Name
Volatile Scrn, USpecimen Type
UrineContainer/Tube: Plastic, 10-mL urine tube (Supply T068)
Specimen Volume: 10 mL
Collection Instructions:
1. Collect a random urine specimen.
2. No preservative.
Additional Information: Submitting less than 10 mL will compromise our ability to perform all necessary testing.
Specimen Minimum Volume
1 mL
Specimen Stability Information
| Specimen Type | Temperature | Time |
|---|---|---|
| Urine | Refrigerated (preferred) | 72 hours |
| Frozen | 14 days | |
| Ambient | 24 hours |
Clinical Information
Urine provides a medium for easy screening.
Reference Values
METHANOL
Not detected (Positive results are quantitated.)
Cutoff concentration: 10 mg/dL
Toxic concentration: ≥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: ≥10 mg/dL
ACETONE
Not detected (Positive results are quantitated.)
Cutoff concentration: 10 mg/dL
Toxic concentration: ≥10 mg/dL
Cautions
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.
