5-Panel vs. 10-Panel Drug Test: What Employers Use

Medically reviewed by the clinical team at Immediate Care Center of Westmont · Published July 23, 2026 · Last reviewed July 23, 2026

At Immediate Care Center of Westmont, our walk-in urgent care performs non-DOT workplace drug testing for employers and job seekers throughout DuPage County, including Downers Grove, Hinsdale, Oak Brook, Darien, Clarendon Hills, Willowbrook, La Grange, and Villa Park. If your employer has asked you to complete a drug screen, you may have seen the terms “5-panel” and “10-panel” and wondered what the difference is. This guide breaks down what each panel tests for, why employers choose one over the other, and how to prepare — so there are no surprises on the day of your test.

Please note: Immediate Care Center of Westmont offers non-DOT drug testing only. We do not provide DOT, CDL, or FMCSA regulated drug testing. The information below refers to employer-directed, non-DOT workplace screening.

What Does “Panel” Mean in a Drug Test?

The word “panel” simply refers to the number of drug classes a test screens for. A 5-panel test looks for five categories of substances; a 10-panel test looks for ten. The most common method for both is a urine sample, though other sample types exist. A general overview of how these tests work and what results mean is available from the MedlinePlus Drug Testing resource maintained by the National Library of Medicine.

It helps to understand the history. The traditional 5-panel is rooted in the federal workplace testing standard, and the federal drug-testing framework is administered by SAMHSA, whose Drug-Free Workplace Programs set the model many private employers follow. Non-DOT employers, however, are not bound by that federal panel and can customize what they screen for based on their industry, safety needs, and workplace policy.

The 5-Panel Drug Test

The 5-panel urine test is the most common workplace drug screen. It targets five widely misused substance categories:

• Marijuana (THC) — the active compound in cannabis.
• Cocaine — including its metabolites.
• Amphetamines — a class that includes methamphetamine.
• Opioids — traditionally opiates such as codeine and morphine; many modern panels expand this group.
• Phencyclidine (PCP) — sometimes called “angel dust.”

For many employers, the 5-panel provides a practical, cost-effective screen that covers the substances most associated with workplace safety and impairment concerns. It is frequently paired with a pre-employment physical as part of the hiring process.

The 10-Panel Drug Test

A 10-panel test includes the same five categories as above and adds five more classes of drugs. While the exact additions can vary by employer and laboratory, a 10-panel commonly adds substances such as:

• Barbiturates — sedatives such as phenobarbital.
• Benzodiazepines — anti-anxiety and sedative medications such as diazepam and alprazolam.
• Methadone — used in pain management and opioid treatment.
• Propoxyphene — an older prescription pain medication.
• Methaqualone — a sedative, now largely historical.

Because several of these additional categories include prescription medications, disclosing your prescriptions at the time of testing is especially important with a 10-panel screen. A benzodiazepine or methadone prescription, for example, can legitimately explain a result, and documenting it up front helps avoid confusion.

5-Panel vs. 10-Panel: Which Do Employers Use?

There is no single “right” panel — the choice depends on the employer’s industry, role, and policy. In general:

• The 5-panel is often used for general employment, entry-level, and many private-sector roles. It is efficient and covers the most common substances of concern.
• The 10-panel is more often used for positions of higher responsibility or safety sensitivity, roles with access to medications, and some healthcare, government, and professional settings — anywhere an employer wants broader coverage that includes certain prescription classes.

Some employers also choose expanded panels or add substances like alcohol depending on their needs. The bottom line for a job seeker is simple: your employer decides which panel you take. If you are unsure, ask your employer or check the paperwork they provided. Our non-DOT drug testing service can perform the panel your employer specifies.

Why the Number of Panels Matters

It is easy to assume that a bigger panel is automatically “stricter,” but that is not quite how it works. A 10-panel does not make it harder to pass — it simply looks at more categories of substances. For someone who does not use any of the drugs being screened, a 5-panel and a 10-panel produce the same clear result. The practical difference is coverage. An employer choosing a 10-panel usually wants visibility into additional classes, several of which are prescription medications, because of the responsibilities or safety demands of the role. That is precisely why disclosure is the most important thing a candidate can do. A test result on its own is just data; the context of a legitimate, disclosed prescription is what allows that data to be interpreted correctly. Approaching either panel honestly and with your medication list in hand is the single best way to ensure a smooth process.

How the Test Works

For a standard urine screen, the process is quick and straightforward:

• You provide a photo ID and any required paperwork from your employer.
• You give a urine sample following the collection instructions provided.
• The sample is screened; non-negative results are typically sent for confirmatory laboratory testing.
• When a prescription could explain a result, that information is reviewed as part of the process.

This is why honesty about your medications matters so much. A legitimate prescription, disclosed at collection, provides the context needed to interpret a result fairly.

How to Prepare for Your Drug Test

• Bring a valid photo ID and your employer’s test request or paperwork.
• List all prescription and over-the-counter medications you take, and be ready to disclose them.
• Hydrate normally so you can provide a sample, but avoid excessive water loading.
• Know which panel your employer ordered, if possible, so you know what to expect.

Because we are a walk-in clinic with an on-site lab, many employees can complete their screen — and any accompanying occupational medicine services — in a single visit.

A Note on Safety

A drug screen is a routine, non-emergency procedure. However, if you are ever experiencing a medical emergency — such as chest pain, difficulty breathing, a suspected overdose, severe confusion, or loss of consciousness — do not come in for a routine visit. Call 911 immediately.

Frequently Asked Questions

What’s the main difference between a 5-panel and 10-panel test?

Both screen for marijuana, cocaine, amphetamines, opioids, and PCP. The 10-panel adds five more classes — commonly barbiturates, benzodiazepines, methadone, propoxyphene, and methaqualone — several of which are prescription medications.

Which panel will my employer use?

That is set by your employer, not the clinic. The 5-panel is most common for general employment, while the 10-panel is often chosen for safety-sensitive or higher-responsibility roles. Check your paperwork or ask your employer.

What if I take prescription medication?

Disclose it at the time of testing. A valid prescription can legitimately explain certain results and is documented as part of the process. This is especially relevant for the additional categories on a 10-panel test.

How much does a workplace drug test cost?

Cost depends on the panel your employer orders and how billing is handled. Because these details vary, we do not list a flat price here. Please see our cost and insurance page or call us for current information.
