ETG Alcohol Drug Test Cups

An ETG test detects ethyl glucuronide, a direct metabolite your body produces after drinking alcohol. Because ETG remains in urine long after ethanol itself is gone, ETG testing extends the alcohol detection window to up to about 80 hours — the standard tool for abstinence monitoring in courts, treatment, and probation programs.

ETG is typically detectable for up to about 80 hours after drinking, depending on the amount consumed, individual metabolism, and the test cutoff. Heavy drinking is detectable longer than a single drink. This window is why ETG — not a breathalyzer — is used to verify several days of abstinence.

MayFlower cups use an ETG cutoff of 300 ng/mL, a threshold chosen to identify genuine alcohol consumption while reducing the chance that incidental exposure (for example hand sanitizer or mouthwash) triggers a positive. Programs with zero-tolerance policies sometimes confirm low-level ETG positives with laboratory LC-MS/MS testing.

Incidental exposure can produce low levels of ETG, which is exactly why cutoff selection and confirmation policies matter. A 300 ng/mL cutoff screens out most incidental exposure while still detecting drinking. When a result is disputed or carries serious consequences, accredited laboratories confirm ETG quantitatively by LC-MS/MS.

Drug courts and DUI programs verifying court-ordered abstinence, probation and parole departments, inpatient and outpatient addiction treatment, transplant and liver programs, family courts, and safety-sensitive employers. Any program where ‘did not drink this weekend’ must be verified objectively uses ETG. See the ETG alcohol drug test cups collection.

A breathalyzer measures alcohol present in the body right now — a window of hours. An ETG urine test measures a metabolite that documents drinking over the past several days. Programs use breath tests for immediate impairment checks and ETG cups for abstinence compliance over time.

Yes. ETG is integrated into multi-panel cups — the 12 panel cup with ETG and fentanyl, the 14 panel cup, and the 16 panel cup — so one collection covers both drug screening and alcohol abstinence. This eliminates separate alcohol testing and simplifies chain of custody.

No. ETG is a qualitative or semi-quantitative marker: it shows that alcohol was consumed within the detection window, not the precise amount or time. Higher concentrations generally suggest heavier or more recent drinking, but results should be interpreted as evidence of use, and disputed results confirmed by a laboratory.

Like every immunoassay strip: two lines (C and T) mean negative — ETG below the 300 ng/mL cutoff — and one line at C only means a preliminary positive. A faint test line still counts as negative. Read at 5 minutes, verify specimen temperature (90–100 °F) at collection, and document the result per program policy.

Store cups at room temperature (2–30 °C), protect from freezing, and rotate stock by the printed expiration date for reliable sensitivity. Programs order by the case with volume-tiered pricing and free shipping on 100+ cups — see the wholesale collection for case quantities.
