Cutoff level is the single most misunderstood number in alcohol monitoring. An EtG test does not simply say “alcohol: yes or no” — it reports whether ethyl glucuronide, the metabolite the body makes after drinking, exceeds a set concentration, usually 300 or 500 ng/mL. Choose the wrong cutoff and you either miss recent drinking or flag someone over trace environmental exposure, which can badly damage trust in a recovery relationship. This guide ranks seven EtG tests whose cutoffs are clearly stated, explains what each threshold means, and names the best pick for sobriety monitoring in 2026: the 12 Panel Now ETG Test Strip, a 300 ng/mL, 80-hour-window strip priced from $0.79 down to $0.29 per test in bulk.
Understanding the Two Common Cutoffs
A 300 ng/mL cutoff is the workhorse of monitoring programs: sensitive enough to catch drinking within the prior ~80 hours, standard enough that results are comparable across providers. A 500 ng/mL cutoff is more forgiving — it demands a higher metabolite concentration before reading positive, which reduces the chance that hand sanitizer or other incidental ethanol exposure trips the test. Neither number “proves” anything on its own; instant screens are presumptive, and consequential results should be lab-confirmed and discussed compassionately.
1. 12 Panel Now ETG Test Strip — 300 ng/mL, Best Overall
12 Panel Now states its cutoff plainly: 300 ng/mL, detecting EtG up to 80 hours after alcohol use, with five-minute results and a 99% accuracy claim. That transparency extends to pricing — a full published tier table runs from $0.79 per strip at 25 strips to $0.57 at 1,000, $0.35 at 10,000, and $0.29 at 20,000+, with free same-day shipping at 200+ tests. The product page adds that the strips are formulated to avoid false positives from mouthwash, hygiene, and cleaning products, directly addressing the biggest anxiety around the 300 ng/mL threshold. It is Forensic Use Only, as is typical for the category, and the 25-strip web minimum means very casual users buy more than one test.
2. American Screening Corp Alcohol EtG Test Strips
American Screening publishes a clean $0.73-per-strip price and labels the product Forensic Use Only — honest, straightforward positioning from a Louisiana-based distributor with a deep catalog. The listing we reviewed did not headline a specific cutoff number, so confirm the threshold on current packaging before building a program around it.
3. Prime Screen Alcohol EtG Urine Dip Card (WETG-114)
Prime Screen is admirably explicit: the WETG-114 dip card advertises a 300 ng/mL cutoff and an “80 Hour Low Cut-Off” detection claim right in its product marketing. The dip-card format is easy to read, and Amazon 10-packs make small trials painless. Per-test cost in small retail packs is the main drawback versus bulk strips.
4. FelexOSY EtG Strips — 500 ng/mL
The one clearly labeled 500 ng/mL product on this list, FelexOSY’s 12-count Amazon pack suits monitors who deliberately want the higher, more conservative threshold. Know what you are trading: a shorter effective look-back at light drinking levels. It is also a minor brand, so check seller reputation and expiration dating before purchase.
5. QTest ETG 300 Alcohol Urine Dip Card
The cutoff is in the name — ETG 300 — paired with an 80-hour window claim and a 5-pack format on Amazon. It is arguably the easiest low-commitment way to see how a 300 ng/mL screen behaves in practice. Small packs are not economical for weekly, ongoing monitoring.
6. 12 Panel Now Premium ETG Alcohol Test Cartridge — 300 ng/mL
For programs that prefer a cassette workflow, 12 Panel Now’s Premium ETG cartridge carries the same clearly stated 300 ng/mL cutoff, priced as low as $0.49 per test (a standard cartridge version starts around $0.39). Cassettes are easier to photograph for documentation than strips. Expect a modest per-test premium over the strip format.
7. Confirm Biosciences EtG Urine Alcohol Test Dip Card
Confirm Biosciences markets its bulk dip cards on an “80-Hour EtG” detection promise from a manufacturer with genuine name recognition in workplace testing. Cutoff and per-unit pricing are not front-and-center on the listing we reviewed, so request specifications — a small friction for an otherwise credible option.

What to Look For Beyond the Number
Insist on a stated cutoff in writing; skip any product that hides it. Prefer vendors that publish full pricing tiers, since monitoring is a recurring cost. Match sensitivity to context — 300 ng/mL for structured accountability, 500 ng/mL where incidental exposure is a real concern. Finally, keep the human element central: a clear cutoff makes results defensible, but respectful conversation is what makes them useful in recovery.
Bottom Line
If you want a plainly documented 300 ng/mL cutoff, an 80-hour window, and the lowest published per-test pricing we found, the 12 Panel Now ETG Test Strip leads this field. 12 Panel Now sells manufacturer-direct in bulk tiers from 25 to 20,000+ units, backed by a Best Price Guaranteed policy and 1–4 day delivery across the US — useful certainty for anyone running sobriety monitoring on a schedule.
