How to Start a Drug Testing Business

At minimum, most people start with DOT urine collection. Adding breath alcohol (BAT) services expands your market but requires its own training and equipment. Non-DOT testing is included. Do not think of it as “DOT minus the rules” — it runs on a different set of sources: applicable state and local law, employer policy, a contract or collective bargaining agreement, applicable federal employment law (ADA, EEOC and similar), and any programme-specific requirements of the client you collect for.

Search your state's Secretary of State business name database before getting attached to a name. Your name does not need to contain "DOT" or "drug testing" — but it should be professional and available.

A standard LLC is appropriate for DOT testing. Part 40 does not create a federal collector-business licence and does not prescribe an entity type — but that is a statement about federal Part 40 only. State and local requirements must be checked separately: depending on your jurisdiction and your mix of services, laboratory, collection-station, occupational-health, professional or general business licensing can still apply. File Articles of Organization with your state's Secretary of State. Use broad business purpose language — "occupational health and drug testing services" or simply "any lawful purpose." NAICS code 621999 is the standard choice for most DOT testing businesses.

Free from IRS.gov. This is your business's federal tax ID. You need it to open a business bank account, file taxes as a business entity, and sign certain contracts. Apply online — it takes minutes and is issued immediately.

Keep business and personal finances separate from day one. Mixing the two can void your LLC's liability protection. Bring your Articles of Organization and EIN to the bank.

General liability insurance is the minimum. Professional liability (errors & omissions) coverage is strongly recommended for anyone performing specimen collections or breath alcohol testing. Some clients and C/TPAs will require proof of insurance before placing collections with you.

Even for a single-member LLC, an operating agreement is strongly recommended. It documents ownership, how the business is managed, and how profits are handled. Some states require it; many banks and contracts ask for it.

Required under 49 CFR Part 40.33. Training covers the entire collection process — from greeting the donor and reviewing the CCF to handling temperature failures, shy bladder situations, and fatal flaws. Part 40 requires qualification training followed by five consecutive error-free mock collections (§40.33) — it does not prescribe a separate federal written examination. TestRight additionally requires a knowledge test as our own course standard.

BAT training is a separate qualification covering breath alcohol testing procedures, EBT device operation, documentation using the ATF, and handling refusals. You must have access to an approved EBT device before you can complete the hands-on portion of training — plan your device purchase before starting BAT coursework.

Understand the six reasons for DOT testing (pre-employment, random, post-accident, reasonable suspicion, return-to-duty, follow-up), the substances tested, and the cutoff levels. This knowledge is essential when collectors interact with clients and donors.

Your training certificate, mock collection records, and any employer documentation are your credentials. Keep documentation showing you currently meet §40.33(g) / §40.213(g); retaining older records indefinitely is a sound business practice rather than a Part 40 mandate — these are what you present to C/TPAs, clients, and auditors. There is no formal federal registry for collectors or BATs; your paperwork is your proof.

Use the current Federal CCF for every DOT collection — never a non-Federal or expired form (§40.40(a)–(b)). It does not have to arrive pre-printed: §40.40(c)(2) allows the required information to be preprinted, typed, or handwritten. Your C/TPA or HHS‑certified lab will normally supply these. Check which version you are being sent. The revised 2026 Federal CCF took effect 27 April 2026 (paper or electronic). The 2023 CCF may still be used, and through 30 May 2027 using it requires no memorandum for the record; from 31 May 2027 using the 2023 CCF requires an MFR under §40.205(b)(2). These dates come from ODAPC guidance rather than the text of Part 40. Be careful how this is stated: what §40.40(b) prohibits is using a non‑Federal form or an expired CCF — it does not require that forms come from any particular supplier, nor that every CCF be laboratory‑printed and barcoded. In practice a particular laboratory may require its own account‑specific, pre‑barcoded forms so specimens can be accessioned to your account. That is a laboratory or operational requirement, not a universal Part 40 rule — confirm what your lab needs before ordering.

Standard DOT urine collection supplies include: specimen collection cups with temperature strips, specimen bottles with tamper-evident seals, gloves, bluing agent (toilet bowl bluing tablet), security seals, and a leak-resistant bag for specimen transport. Your C/TPA can often provide starter kits or supply lists.

Breath alcohol testing requires an Evidential Breath Testing (EBT) device from the DOT conforming products list. These devices are a significant upfront investment. Research models, compare features, and verify the device is on the current NHTSA conforming products list before purchasing. Do not buy a used device without confirming it is still on the CPL and has current calibration records.

It depends on the purpose of your testing, not the device label. Testing for employment decisions is forensic and exempt from CLIA — which is why most workplace TPAs use Forensic Use Only (FUO) devices. Testing for a clinical / medical purpose falls under CLIA. A Certificate of Waiver covers waived tests only — CLIA also has moderate- and high-complexity categories with their own certificate, compliance or accreditation requirements (42 CFR §§493.5, 493.15), so match the certificate to the complexity of the testing you actually perform. DOT testing always ships to an HHS-certified lab, so CLIA never applies at the collection site for DOT. Check before buying devices — and don't take on a Certificate of Waiver you don't need: it commits you to the clinical-testing regime (exact IFU compliance, quality control, documentation, inspection).

A Consortium/Third-Party Administrator (C/TPA) bundles lab access, CCF forms, MRO services, and often random pool management into one relationship. Most independent collectors join a C/TPA rather than contracting directly with a lab — it is simpler, requires less volume commitment, and the C/TPA handles the back-end compliance work. Direct lab contracts may make sense once you have significant volume.

If not using a C/TPA, you will need to establish an account directly with a SAMHSA-certified laboratory. Major providers include LabCorp, Quest Diagnostics, USDTL, CRL, and others. Each requires a collection account, provides lab-specific CCFs, and has its own shipping process.

All DOT drug test results — negatives included — go through the MRO before being reported to the employer. §40.163(a) makes it the MRO’s responsibility to report all drug test results, and §40.165(a) requires all results to be reported to the DER. Non-negatives require the MRO’s individual review and verification interview; negatives may be reviewed in a streamlined way (§40.123 caps required negative review at 500 per quarter) and may be reported by electronic data file — but they are still part of the MRO process, not a bypass of it. Your C/TPA or lab will have an MRO relationship — understand how this works, the typical turnaround, and what happens when a donor requests a split specimen test.

Specimens must be shipped to the lab in a timely, chain-of-custody-compliant manner. Your C/TPA or lab will provide instructions on shipping carriers, packaging, and documentation. Understand this process before your first live collection — a broken chain of custody can invalidate a specimen.

DOT testing records have specific retention periods. Under §40.333: five years for verified positives, refusals, alcohol results of 0.02 or greater and SAP/follow-up records; one year for negatives and alcohol results below 0.02. The two-year figure for random selection records is not a universal Part 40 rule — it comes from the modal regulation, so check the agency rule that applies to you rather than assuming two years everywhere. You need a filing system (physical or digital) that keeps records organized, confidential, and accessible for audits. Set this up before your first collection.

DOT-regulated employers must have a written drug and alcohol policy, a designated employer representative (DER), and their safety-sensitive employees enrolled in a random testing program. Being able to answer basic employer compliance questions is a competitive advantage — and prevents you from facilitating a testing program that is not set up correctly.

These are the two testing situations most likely to be mishandled. Post-accident triggers and timing are modal-specific. Under FMCSA §382.303(d): if the alcohol test is not done within 2 hours you document why and keep trying, stopping at 8 hours; drug-test attempts stop at 32 hours. Other agencies differ. Reasonable suspicion testing requires a trained supervisor — the collector's role is to execute the collection, not evaluate whether the referral was warranted.

DOT drug testing has its own vocabulary. Being fluent in the terminology — CCF, ATF, EBT, MRO, DER, SAP, split specimen, fatal flaw, shy bladder — builds credibility with clients and prevents errors in documentation.

Your best early clients are small DOT-regulated employers — trucking companies (FMCSA), construction firms with CDL drivers, transit operators — who need ongoing testing but do not have a dedicated collection site nearby. Transportation companies, staffing agencies, and occupational health clinics are also strong targets. Know which DOT agencies apply to your local market.

Non-DOT employers — any business that wants drug testing but is not federally regulated — are a large and underserved market. Non-DOT testing is often modelled on the DOT process, but “fewer rules” is the wrong mental model: what applies is simply a different set of sources. Requirements can come from state and local law (several states impose detailed statutory testing requirements, and some regulate notice, specimen types, confirmation, or observed collections), employer policy, a contract or collective bargaining agreement, a state drug‑free‑workplace incentive programme, or a federal overlay such as ADA/EEOC considerations. Check the jurisdiction before assuming a DOT practice carries over. You can use the same skills and many of the same supplies. Non-DOT testing is included in both the Collector and BAT training programs.

As you build employer relationships, you can expand into C/TPA services — managing random testing pools, coordinating MRO services, maintaining employer files, and providing compliance consulting. This is one of the highest-margin add-ons in the drug testing business because it creates recurring monthly revenue from each employer account.

The 60+60 figure is an FMCSA requirement, not a universal Part 40 one. §382.603 requires employers to ensure that persons designated to supervise drivers receive at least 60 minutes of training on alcohol misuse plus at least a further 60 minutes on controlled substances use; §382.603 also states that recurrent supervisor training is not required. Other DOT modes set their own supervisor-training rules, so check the modal rule that applies. Note too that §382.603 reaches people designated to supervise drivers — an owner‑operator who employs only himself or herself has designated no one to supervise. Many employers do not know this requirement exists. Offering this training positions you as a compliance partner, not just a collection site.

DOT regulations under 49 CFR Part 40 are updated periodically. Subscribe to DOT/ODAPC updates, follow your C/TPA's compliance communications, and revisit your knowledge base when regulatory changes are announced. Your credibility as a compliance resource depends on staying current.
