Choosing the right drug screening panel is one of the most important decisions an employer, safety manager, or healthcare professional can make. Whether you are setting up a workplace testing program for the first time or upgrading an existing protocol, understanding the difference between a 5 panel drug screening, a 7 panel drug screening, and a 10 panel drug screening can save you time, money, and legal headaches.
This guide breaks down every major panel type, the exact substances each one detects, detection windows by specimen type, the latest federal regulations for 2026, and practical advice for selecting the right test for your organization.
What Is a Drug Screening Panel?
A drug screening panel is a predefined group of substances that a single test checks for simultaneously. Panels are named by number — a 5 panel drug screening tests for five substance classes, a 10 panel screens for ten, and so on.
The concept was standardized in the 1980s when the Substance Abuse and Mental Health Services Administration (SAMHSA) established the original five-drug panel for federal workplace testing. Since then, employers and laboratories have developed extended panels to keep pace with evolving patterns of substance use.
The panel you choose determines the scope of your screening program, its cost, its legal defensibility, and its relevance to the risks you are trying to mitigate. There is no universal "best" panel — the right choice depends on your industry, regulatory obligations, and the specific safety concerns of each role.
The 4 Panel Drug Screening
A 4 panel drug screening is a stripped-down version of the standard five-drug test. It typically screens for:
- Amphetamines (including methamphetamine)
- Cocaine (benzoylecgonine metabolite)
- Opiates (codeine, morphine, heroin metabolite 6-MAM)
- Marijuana (THC metabolite, THC-COOH)
The 4 panel drug screening omits PCP (phencyclidine), which has declined in prevalence in many regions. Some employers in states where marijuana use has been legalized also use a modified 4-panel that replaces THC with another substance class.
This panel is most common among private employers in low-risk industries who want a basic, cost-effective screening. It is not suitable for DOT-regulated roles or any position governed by federal testing requirements.
The 5 Panel Drug Screening: The Industry Standard
The 5 panel drug screening is the most widely used drug test in the United States. It is the mandatory panel for all Department of Transportation (DOT) regulated testing and the baseline for federal workplace programs governed by SAMHSA.
What does a 5 panel drug screening test for?
| # | Substance Class | Common Drugs Detected | Standard Cutoff (Urine) |
|---|---|---|---|
| 1 | Marijuana (THC) | Cannabis, edibles, concentrates | 50 ng/mL (screen) / 15 ng/mL (confirm) |
| 2 | Cocaine | Cocaine, crack cocaine | 150 ng/mL (screen) / 100 ng/mL (confirm) |
| 3 | Amphetamines | Amphetamine, methamphetamine, MDMA | 500 ng/mL (screen) / 250 ng/mL (confirm) |
| 4 | Opiates | Codeine, morphine, heroin (6-MAM) | 2000 ng/mL (screen) / 2000 ng/mL (confirm) |
| 5 | Phencyclidine (PCP) | PCP ("angel dust") | 25 ng/mL (screen) / 25 ng/mL (confirm) |
The 5 panel drug screening targets the substances most commonly associated with impairment in the workplace. According to Checkr, this is the go-to panel for both private employers and government agencies looking for a proven, legally defensible testing framework.
2025–2026 update: fentanyl added to DOT panels
A major regulatory shift is underway. In January 2025, SAMHSA published updated Mandatory Guidelines for federal workplace drug testing, adding fentanyl and norfentanyl to the authorized testing panels. These changes took effect on July 7, 2025.
For DOT-regulated employers, fentanyl testing has become a standard requirement in 2026, effectively turning the traditional 5-panel into a 7-substance screen. The DOT compliance updates for 2026 reflect this shift, making it critical for motor carriers, airlines, railroads, and pipeline operators to update their testing protocols.
The 7 Panel Drug Screening
A 7 panel drug screening extends the standard five-drug test by adding two additional substance classes. While the specific composition can vary by laboratory, the most common configuration includes:
Everything in the 5-panel, plus:
| # | Additional Substance | Common Drugs Detected |
|---|---|---|
| 6 | Benzodiazepines | Diazepam (Valium), alprazolam (Xanax), lorazepam (Ativan), clonazepam (Klonopin) |
| 7 | Barbiturates | Phenobarbital, secobarbital, butalbital |
Both benzodiazepines and barbiturates are prescription medications with significant sedative effects. They pose a particular risk in safety-sensitive roles because they can cause drowsiness, impaired motor coordination, slowed reaction time, and confusion — all of which are incompatible with operating machinery, driving, or making critical decisions.
The 7 panel drug screening is popular in healthcare settings, law enforcement agencies, and industries where employees may have access to prescription medications. Mobile Health notes that employers increasingly choose the 7-panel when they want coverage beyond street drugs but do not need the breadth of a 10-panel.
The 9 Panel Drug Screening Test
The 9 panel drug screening test adds four more substance classes to the standard 5-panel, offering broader coverage while stopping short of the full 10-panel scope. A typical 9-panel includes:
Everything in the 5-panel, plus:
| # | Additional Substance | Why It Matters |
|---|---|---|
| 6 | Benzodiazepines | Widely prescribed anti-anxiety medications with high abuse potential |
| 7 | Barbiturates | Central nervous system depressants that cause impairment |
| 8 | Methadone | Synthetic opioid used in pain management and addiction treatment |
| 9 | Propoxyphene | Opioid painkiller (discontinued in the U.S. but still detected) |
The 9-panel is particularly relevant in an era of rising opioid misuse because it captures methadone, a synthetic opioid that standard opiate immunoassays often miss. Employers in the construction, manufacturing, and transportation sectors frequently opt for this panel to address the full spectrum of opioid risk.
Modern portable oral fluid drug screening devices like the Altiscreen A1 can test for up to nine substance classes in a single saliva test, delivering results on-site in under 30 seconds. This eliminates the traditional tradeoff between panel breadth and testing speed — organizations no longer have to choose between comprehensive saliva-based screening and fast results.
The 10 Panel Drug Screening
A 10 panel drug screening is the most comprehensive standard panel available. It is widely used for employees in safety-sensitive positions, government workers, law enforcement officers, and healthcare professionals.
What does a 10 panel drug screening test for?
Everything in the 5-panel, plus:
| # | Additional Substance | Common Drugs Detected |
|---|---|---|
| 6 | Benzodiazepines | Xanax, Valium, Klonopin, Ativan |
| 7 | Barbiturates | Phenobarbital, secobarbital |
| 8 | Methadone | Dolophine, methadose |
| 9 | Propoxyphene | Darvon, Darvocet (discontinued but still testable) |
| 10 | Methaqualone | Quaalude (rare but included in standard panels) |
As Medical News Today explains, the 10 panel drug screening is designed to cast the widest net for both illicit street drugs and commonly misused prescription medications. It is the standard for roles where public safety is directly at stake.
Some laboratories now offer expanded 12-panel or 14-panel versions that add synthetic opioids (fentanyl, tramadol), extended opiates (oxycodone, hydrocodone), or synthetic cannabinoids. As noted by Talcada, these expanded panels are gaining traction as employers respond to the evolving landscape of substance use.
Does Kratom Show Up on a Drug Screening?
This is one of the most searched questions in drug screening today — and the answer matters for both employers and individuals.
No, kratom does not show up on standard 5, 7, 9, or 10 panel drug screenings. The active alkaloids in kratom — mitragynine and 7-hydroxymitragynine — are not included in any of the routine testing panels used in workplace, DOT, or federal screening programs.
In January 2025, when SAMHSA published its updated authorized testing panels, kratom was not listed among the required substances. This means federal workplace programs do not screen for it.
However, kratom can be detected through specialized testing. Labcorp offers a dedicated kratom panel (test code 791750) that uses immunoassay screening at 5.0 ng/mL with LC-MS/MS confirmation at 1.0 ng/mL cutoffs. Employers who want to screen for kratom must specifically add this test to their program — it will never appear on a standard panel by default.
Kratom detection windows
If a specialized kratom test is ordered, detection windows are approximately:
- Urine: 6 hours to 7 days after ingestion
- Blood: Up to 24 hours
- Hair: Up to 90 days (though hair-based kratom testing is uncommon)
The growing popularity of kratom, combined with its ambiguous legal status in several U.S. states, makes this an area to watch. Employers operating in states where kratom is banned may want to consider adding a specialized panel. For on-site oral fluid screening with customizable substance panels, portable devices like the Altiscreen A1 allow organizations to tailor their saliva-based testing program as regulations and workplace needs evolve.
DOT vs Non-DOT Drug Screening: Key Differences
Understanding the distinction between DOT and non-DOT drug screening is essential for compliance and for choosing the right panel.
DOT drug screening
DOT drug screening is federally mandated for safety-sensitive employees in transportation industries. The rules are strict and non-negotiable:
- Panel: Fixed 5-panel (now with fentanyl added in 2025/2026), no modifications allowed
- Specimen: Urine only (oral fluid approval is pending)
- Testing occasions: Pre-employment, post-accident, random, reasonable suspicion, return-to-duty, follow-up
- Laboratory: Must be HHS-certified
- MRO review: Every positive result must be reviewed by a Medical Review Officer
- Regulations: Governed by 49 CFR Part 40
DOT testing applies to drivers, pilots, train operators, pipeline workers, and other safety-sensitive transportation employees. There are no exceptions and no alternative panels — if you are DOT-regulated, the panel is prescribed by law.
Non-DOT drug screening
Non-DOT drug screening gives employers far more flexibility:
- Panel: Employer's choice — 4, 5, 7, 9, 10, 12, or custom panels
- Specimen: Urine, oral fluid, hair, or blood
- Testing occasions: Determined by company policy
- Laboratory: Employer's choice (though accredited labs are recommended)
- Regulations: Governed by state law and company policy
As Cisive notes, non-DOT testing allows companies to customize their approach based on industry-specific risks, regional substance trends, and organizational culture.
For non-DOT workplace screening, Altiscreen’s portable oral fluid drug screening solutions offer the flexibility to configure saliva-based panels and deploy testing on-site across multiple locations — while maintaining fast, reliable screening performance in the field.
Drug Screening Specimen Types: Urine vs Oral Fluid vs Hair
The specimen type you choose affects detection windows, accuracy, ease of collection, and vulnerability to cheating.
Urine drug screening
Urine remains the most common specimen for workplace drug testing. Detection windows are moderate (2–30 days depending on the substance), sample collection is well-established, and costs are low. The main drawbacks are privacy concerns during collection and the relatively high risk of sample adulteration.
According to the National Library of Medicine, urine is the preferred specimen for most regulated testing programs, including DOT and SAMHSA.
Oral fluid (saliva) drug screening
Oral fluid testing has seen explosive growth — usage among employers has increased by more than 40% between 2023 and 2026. Key advantages include:
- Short detection window (5–48 hours) ideal for detecting recent or on-the-job use
- Observed collection dramatically reduces cheating
- No bathroom or private space needed — tests can be administered anywhere
- Non-invasive — less intrusive for the employee
SAMHSA's 2025 guidelines now include authorized oral fluid testing panels for federal programs, signaling growing acceptance of saliva-based screening at the regulatory level.
Portable oral fluid analyzers, such as the Altiscreen A1, bring saliva-based drug screening directly to the field. Results are available in under 30 seconds, making oral fluid one of the fastest pathways from sample collection to actionable information. This is particularly valuable for roadside, workplace, and on-site screening scenarios where immediate saliva-based results are essential.
Hair follicle drug screening
Hair follicle drug screening provides the longest detection window of any method — up to 90 days of drug use history from a single sample. It is particularly effective for identifying chronic or repeat substance use that shorter-window tests might miss.
Hair testing is commonly used in pre-employment screening for high-security positions, court-ordered monitoring, and post-rehabilitation follow-up. The main limitations are higher cost, longer laboratory turnaround time, and the inability to detect very recent use (there is typically a 7–10 day blind spot after drug ingestion before metabolites appear in hair).
How Long Does a Drug Screening Take to Get Results?
Result turnaround depends on the testing method and technology used:
| Method | Typical Result Time |
|---|---|
| Rapid on-site devices (e.g., Altiscreen A1) | Under 30 seconds |
| Point-of-care cup/strip tests | 5–15 minutes |
| Laboratory urine screening | 1–3 business days |
| Laboratory confirmation (GC-MS / LC-MS) | 3–7 business days |
| Hair follicle lab analysis | 5–10 business days |
For employers who need immediate results — such as post-accident screening, reasonable-suspicion testing, or random on-site checks — portable screening technology has eliminated the waiting game. The ability to get a preliminary result in seconds allows supervisors to make safety decisions on the spot, with confirmatory laboratory testing available if needed.
At Home Drug Screening: What You Need to Know
At home drug screening kits have become increasingly popular among individuals preparing for employment tests and parents monitoring for substance use. These over-the-counter kits are typically immunoassay-based and available in 5, 10, or 12 panel configurations.
While convenient, at home drug screening tests have important limitations. According to research cited by consumer testing experts, accuracy varies significantly by brand and substance class. False positives can result from cross-reactivity with over-the-counter medications, foods, or supplements. Additionally, home tests provide only preliminary results — no at-home kit carries the same legal or regulatory weight as a laboratory-confirmed or professional on-site test.
For employers and organizations, professional-grade on-site screening devices provide the accuracy and documentation needed for defensible workplace decisions, while maintaining the convenience and speed of point-of-care testing.
How to Choose the Right Drug Screening Panel
Selecting the optimal panel for your organization comes down to four key factors:
1. Regulatory requirements. If your employees fall under DOT regulations, you must use the prescribed 5-panel (now including fentanyl). No exceptions. Check with the DOT Office of Drug & Alcohol Policy for current requirements.
2. Industry risk profile. High-risk industries (construction, transportation, manufacturing, energy) typically benefit from broader panels (9 or 10 panel) that capture prescription drug misuse alongside illicit substances. Lower-risk office environments may find a 5-panel sufficient.
3. Regional substance trends. The opioid crisis has made expanded opiate detection essential in many regions. Employers in areas with high rates of benzodiazepine or methamphetamine misuse should ensure their panel covers these substances.
4. Operational constraints. Consider where and how testing will happen. If you need results on-site, in the field, or across multiple locations, portable oral fluid analyzers offer the flexibility to screen for up to nine substances per saliva sample without relying on laboratory infrastructure.

Frequently Asked Questions
Does alcohol show up in a drug screening?
Standard drug screening panels (4, 5, 7, 9, or 10 panel) do not test for alcohol. Alcohol testing requires a separate breath test (breathalyzer) or an EtG/EtS urine test. Some employers add alcohol to their screening program as a separate test alongside the drug panel.
How much does a drug screening cost?
Costs vary by panel size, specimen type, and whether the test is conducted on-site or in a laboratory. A basic 5-panel urine test typically costs $30–$60 per test. A 10-panel runs $50–$100. On-site rapid oral fluid testing with portable devices can reduce per-test costs over time by eliminating laboratory fees, collection site expenses, and employee downtime associated with off-site testing.
What is a non-DOT drug screening?
A non-DOT drug screening is any drug test that is not governed by Department of Transportation regulations. Non-DOT tests give employers full discretion over the panel size, specimen type, testing frequency, and substances included. They are used by private companies, healthcare organizations, and other employers outside the federal transportation sector.
Can you fail a drug screening for prescription medications?
Yes. If a prescription medication contains a substance included in the testing panel (such as amphetamines in Adderall, opiates in codeine-based cough medicines, or benzodiazepines in Xanax), it will trigger a positive result. In DOT-regulated testing, a Medical Review Officer (MRO) will contact the donor to verify a valid prescription before reporting the result. In non-DOT testing, the process varies by employer policy.
How long do drug screening results take?
On-site rapid oral fluid screening devices deliver preliminary saliva-based results in seconds to minutes. Laboratory-based testing typically takes 1–3 business days for a negative result and 3–7 business days for a confirmed positive (which requires secondary confirmation testing using GC-MS or LC-MS/MS). See our detailed breakdown above.
The Future of Drug Screening: Portable, Fast, and Flexible
The drug screening landscape is shifting toward on-site, real-time testing. The global workplace drug testing market continues to grow, driven by stricter regulations, the ongoing opioid crisis, and technological advances that make sophisticated screening accessible outside the laboratory.
Portable oral fluid drug screening devices represent the cutting edge of this transformation. The ability to screen for multiple substances on the spot using saliva samples eliminates many of the delays, logistics challenges, and costs associated with traditional lab-based testing. Devices like the Altiscreen A1 combine the speed and convenience of point-of-care saliva testing with high analytical performance, making fast, on-site drug screening accessible for organizations of any size.
Whether you operate a fleet of commercial vehicles, manage construction sites, run a healthcare facility, or oversee an industrial workforce, the right combination of panel selection, specimen type, and testing technology can help you build a drug screening program that protects your people, satisfies regulators, and fits your operational reality.
