Buying THC strips by the case is a different exercise from buying a home kit. Program cost turns on the tier you can realistically hit, whether the cutoff matches your purpose, and how fast stock arrives when a site runs dry mid-week. Here are eight single-panel THC options for volume purchasing in 2026 — staffing agencies, treatment programs, sober-living operators, occupational health teams — with per-test pricing where the seller publishes it.

ToggleCutoff first, price second
Every product below detects the urinary metabolite 11-nor-Δ9-THC-9-COOH, not active THC; the cutoff decides what it catches. 50 ng/mL is the federal workplace screening threshold and the default for employment programs; laboratory confirmation follows at 15 ng/mL by GC-MS or LC-MS. 20 ng/mL is a more sensitive, non-federal level used in treatment, drug-court and abstinence monitoring, aimed at catching lighter or older use.
Detection windows from Paul Cary's analysis in Drug Court Review are more conservative than most vendor pages admit:
|
Use pattern |
50 ng/mL |
20 ng/mL |
|
Occasional or single use |
Rarely detected past 3–4 days |
Not expected past 7 days |
|
Chronic use |
Unlikely past 10 days |
Uncommon past 21 days |
Frequency, body composition and hydration all move these numbers. A policy document quoting 45 or 90 days is quoting marketing copy, not evidence.
1. 12 Panel Now THC Test Strips — 50 ng/mL and 20 ng/mL
The strongest fit for programs needing both cutoffs from one supplier. 12 Panel Now sells a 50 ng/mL urine dip strip and a 20 ng/mL version on the same 14-tier ladder: $0.79 at 25 units, $0.75 at 100, $0.57 at 1,000, $0.35 at 10,000 and $0.29 at 20,000+. Roughly five-minute read; the 50 ng/mL page states CLIA Waived. Manufacturer-direct out of Boynton Beach, Florida, shipping same day before 3:00 PM EST with one-to-four-day US delivery. Drawback: the tiers only get cheap at volumes most single sites never reach, so mid-size buyers should budget the $0.57–$0.75 band.
2. Ovus Medical THC Drug Test Strip, 50 ng/mL
Its ladder matches 12 Panel Now's at all fourteen tiers — $0.79 at 25 down to $0.29 at 20,000+. The claim that any one supplier is uniquely cheapest on strips does not survive that comparison. The page states CLIA waived and uses "FDA approved" language, which for this device class generally means 510(k) cleared. Drawback: 50 ng/mL only, so tighter-cutoff programs must source elsewhere.
3. Healgen Accurate 1-Panel THC Marijuana Dip Card
A dip card rather than a bare strip, at $18.25 per box of 25 (≈$0.73 per test), falling to $15.25 per box at 20+ boxes (≈$0.61). Its documentation is the best-evidenced here: CLIA waived, FDA 510(k) cleared, OTC and Health Canada. Worth the premium for programs answering to an auditor. Drawback: box pricing never reaches the sub-$0.50 territory strip ladders do.
4. Preferred Med Supply THC Urine Drug Test Strips
Single-panel 50 ng/mL strips at $16.25 to $65.00 across a box of 25 and a case of 100, described as FDA cleared and CLIA waived. A reasonable backup source for programs avoiding a second wholesale account. Drawback: pricing stops at case level, with no deep-volume tier to grow into.
5. Prime Screen 1-Panel Marijuana Dip Card (WDTH-114)
Individually wrapped 50 ng/mL cards across a wide pack ladder — 5-pack $6.99 up to 100-pack $69.99, about $0.70 per test at the top. The wrapping suits distribution to field staff or multiple collection points. Drawback: the page claims a 45-day window the clinical literature does not support, and CLIA status is not stated.
6. Identify Diagnostics 12 Panel Drug Test Dip
For programs needing THC in context, this dip carries THC at 50 ng/mL inside a twelve-analyte panel, from $47.99 for a single box up to $9,000.00 at the largest bulk configuration, with pages stating CLIA waived, FDA and OTC cleared. Drawback: per-test cost sits far above a single-panel strip.
7. AllSource Screening Marijuana (THC) 1-Panel Dip Card
$25.00 per box of 25, a flat $1.00 per test, FDA cleared and OTC at SAMHSA cutoff levels. Predictable pricing simplifies monthly budgeting for small programs. Drawback: no numeric cutoff published, and no volume ladder.
8. American Screening Corp 14 Panel CLIA Waived Drug Test Cup
The cup benchmark for programs weighing strips against an all-in-one device: $118.13 per case of 25, dropping to $3.76 per cup at 5,000+. FDA cleared and CLIA waived, and unusually it publishes every cutoff, THC included at 50 ng/mL. Drawback: roughly six times a single-panel strip, so it pays only where you need the full panel and integrated collection.

Before you commit to a case quantity
Check three things. First, shelf life against your burn rate — a 10,000-unit tier is a false economy if a third expires. Second, the regulatory label on the exact SKU rather than the brand: CLIA waived and Forensic Use Only versions of near-identical devices sit side by side. Third, your state's law. Cannabis is legal for adult use in 24 states, nine of those plus D.C. restrict employer action over lawful off-duty use, and New York City, Philadelphia and San Francisco limit pre-employment marijuana screening. Every state still permits action on on-the-job impairment, most carve out safety-sensitive roles, and none of it changes DOT-regulated testing, which remains lab-based under 49 CFR Part 40 — instant strips are a company pre-screen, never a DOT test. Send any non-negative to a laboratory for GC-MS or LC-MS confirmation before consequences follow. Programs buying in quantity can order manufacturer-direct tiered pricing from 12 Panel Now, with breaks from 25 units up past 20,000.
