Two types of urine alcohol testing
Traditional ethanol test:
- Tests for active alcohol
- Detection: 12-24 hours
- Cutoff: typically 0.02-0.04 g/dL urine alcohol
- Misses use 24+ hours prior
EtG/EtS metabolite test:
- Tests for alcohol metabolites
- Detection: up to 80 hours
- SAMHSA cutoffs: 100, 500, or 1,000 ng/mL depending on context
- Catches weekend drinking on Monday tests
Which test does Texas DWI probation use?
Depends on case severity and probation officer choice:
- Standard DWI 1st probation: Often traditional ethanol; sometimes EtG
- DWI 2nd or 3rd: EtG common; ankle monitor (SCRAM) sometimes
- Intoxication assault/manslaughter: EtG standard; PEth blood test possible
- Specialty courts (DWI Court): Intensive testing including EtG, PEth, SCRAM
Communicate with probation officer about specific testing protocol. Don't assume traditional alcohol test will be used if EtG cutoffs apply.

Frequently Asked Questions
Can I drink 24 hours before a urine alcohol test?
Depends on test type. Traditional ethanol: probably clear. EtG: probably still positive (up to 80 hours).
What's SCRAM monitoring?
Continuous alcohol monitoring via ankle bracelet. Detects alcohol through perspiration 24/7. Used for serious DWI cases requiring abstinence verification.
Can probation test for alcohol if I'm not on DWI?
Possibly. Some probation conditions include alcohol prohibition even for non-DWI cases. Check specific probation terms.
Does the type of alcohol matter?
No. All alcoholic beverages produce ethanol; same metabolites; same detection. Beer, wine, liquor all test identically.
Will mouthwash cause urine alcohol positive?
Possibly briefly. Alcohol-containing mouthwash can produce trace amounts. Cutoff levels exclude most incidental exposure. EtG more sensitive than ethanol test for this scenario.
