10 Cotinine Tests Compared for 2026: Urine, Saliva, and Blood

Three specimens dominate nicotine screening, and they are not interchangeable. Urine is cheap, fast and where most testing happens. Saliva is collected under observation and needs no restroom. Blood delivers the tightest thresholds and the most defensible numbers, at the cost of a venipuncture and a lab. All three measure cotinine rather than nicotine: nicotine’s half-life of one to two hours means it is gone before most samples are taken, while cotinine persists at about 16 to 24 hours per half-life. Ten options across all three specimen types for 2026.

1. 12 Panel Now Cotinine (Nicotine) Urine Test Strip

Urine. The price leader and the top pick for programs of any size. Single-panel dip strip at the 200 ng/mL standard cutoff, on a 14-tier ladder: $0.79 at 25 units, $0.57 at 1,000, $0.35 at 10,000, and $0.29 at the 20,000+ tier — so $0.79 is where most buyers start and $0.29 is a top-of-ladder volume price. Manufacturer-direct from Boynton Beach, Florida, with same-day dispatch on weekday orders before 3 PM EST, one-to-four-day US delivery, free shipping above 100 strips, and 18,000+ repeat customers. Drawback: cotinine is strip-only here. The listing states CLIA waived; because that status attaches to a SKU rather than an analyte, verify it before using the strip clinically.

2. Quest Diagnostics Tobacco Cessation (Cotinine) Test

Blood. Quest’s employer biometric screening assay uses specific immunoassay with a positive cutoff of 16 ng/mL — by far the most sensitive threshold here. Quest notes cotinine’s roughly 24-hour half-life and recommends employers offer an appeal process such as a retest or physician affidavit. Drawback: no published pricing, a blood draw is required, and the low cutoff flags exposure urine strips ignore.

3. Abbott iScreen OFD — Cotinine

Saliva. The best-known oral fluid cotinine device, at $199.75 per 25 tests, about $7.99 each. Observed collection makes substitution a non-issue and needs no restroom. Drawback: the most expensive test here, with no published cutoff.

4. American Screening Corp Cotinine Test Strips (COT 200)

Urine. Foil-pouched 200 ng/mL strips at $11.25 per case of 25, roughly $0.45 each, with bulk pricing published between $0.38 and $0.70. The page states CLIA-waived status and calls results presumptive screening only, recommending LC-MS/MS confirmation. Drawback: pricing never reaches the sub-$0.30 tier available elsewhere.

5. Accurate (Healgen) Oral Fluid Drug Test for COT

Saliva. A lower-cost oral fluid alternative at $112.50 per 25 tests, about $4.50 each, from a widely distributed manufacturer. Drawback: no published cutoff, and still several times the cost of a urine strip.

6. Labcorp Test 716555 — Nicotine Metabolite, Screen Only, Urine

Urine, lab. Random 5 mL specimen, immunoassay, negative threshold 0.3 µg/mL — 300 ng/mL, 50% more permissive than the rapid-strip standard. Labcorp notes detection generally out to about seven days post-exposure. Drawback: no published pricing, and lab turnaround instead of a five-minute read.

7. Labcorp Test 071255 — Nicotine and Metabolite, Quantitative

Blood. The quantitative option on plasma, whole blood or serum, for cases where a number matters more than a yes-or-no — appeals, contestable claims, clinical follow-up. Labcorp also lists 070045 for quantitative urine and 737919 for combined screen and confirmation. Drawback: no published pricing, and the most involved collection here.

8. Abbott NicQuick Cotinine/Nicotine Urine Test Cassette (DCT-102)

Urine. A 200 ng/mL cassette at $63.00 per box of 40, roughly $1.58 per test, listed for workplace, CLIA-waived and forensic use. Cassettes are easier to handle and photograph than loose strips. Drawback: several times the cost of a strip.

9. CLIAwaived, Inc. IDTC Rapid Nicotine Test Cards

Urine. A three-line lateral flow card at $140.25 per 40 tests, about $3.51 each, from a large point-of-care distributor. Drawback: neither a cutoff nor a regulatory statement appears on the listing, and it is costly for a rapid urine device.

10. Confirm Biosciences HE-DIP-COT, 1-Panel 200 ng/mL Urine Dip

Urine. A 200 ng/mL dip card distributed through McKesson, useful for clinics already ordering through a major wholesaler. The listing states CLIA Waived. Drawback: no public price, so budgeting requires an account quote.

Specimen and Threshold Comparison

Choosing a Specimen and a Cutoff

Cost per test is the clearest divider: urine strips run under a dollar, saliva devices $4.50 to $8.00, lab tests are quoted rather than listed. But threshold matters more than format. One person can screen negative at Labcorp’s 300 ng/mL, positive on a 200 ng/mL strip, and clearly positive against Quest’s 16 ng/mL blood cutoff on the same afternoon.

Two constants apply across all ten. Detection generally runs two to four days after occasional use and up to about ten days in regular users. And no cotinine test identifies the source — cigarettes, cigars, vapes, pouches, smokeless tobacco, patches and gum all produce it, so someone using nicotine replacement therapy to quit will screen positive.

The Legal Boundary on Employment Testing

Roughly 28 to 29 states plus the District of Columbia — about half of US states, with sources disagreeing on the exact number — have smoker protection laws or broader lawful-off-duty-conduct statutes restricting or barring employment decisions based on legal tobacco use outside work. Some cover tobacco through general lawful-activity provisions rather than tobacco-specific ones. Where those laws apply, a positive result is generally not actionable in hiring or discipline. Insurance underwriting is treated differently, since carriers use tobacco status to set premium class. Confirm your state’s rules with employment counsel before testing applicants or staff.

FAQ

Which specimen is most accurate? Accuracy is largely a function of threshold and handling. Blood at 16 ng/mL detects the least exposure; urine at 200 to 300 ng/mL is the practical workplace standard.

Do vapes and pouches show up? Yes, the same as cigarettes.

Is a rapid result final? No. Treat it as presumptive and confirm non-negatives at a laboratory before acting.
