Hiring the right employees is one of the most critical decisions a company can make — and for employers in Kansas City, pre-employment drug testing plays an essential part for building a safe, reliable, and productive workforce.
But what exactly shows up on a pre-employment drug test? And what should Kansas City employers know before choosing the proper testing solution?

At Test Smartly Labs, we simplify the process by offering walk-in, on-site, and confidential tests for businesses throughout Kansas City, Overland Park, Independence, and surrounding areas. Here’s what employers need to know about what’s detected on a modern pre-employment drug test.

 

What Does a Pre-Employment Drug Test Look For?

Most employers request either a 5-panel, 10-panel, or expanded-panel drug test. These tests screen for the most commonly used illicit substances, as well as prescription drug misuse, depending on your company policy.

Below is a breakdown of the typical panels employers use:

 

Common Drug Panels Used for Pre-Employment Screening

✔ Standard 5-Panel Test (Most Common for Employment)

The 5-panel is the baseline for most workplaces. It detects:

  • Marijuana (THC) 
  • Cocaine 
  • Opiates (heroin, codeine, morphine) 
  • Amphetamines (methamphetamine, MDMA in some cases) 
  • Phencyclidine (PCP) 

This is also the required panel for DOT-regulated employees, with specific federal cutoffs.

✔ 10-Panel Drug Test (Expanded Screening for Higher-Risk Workplaces)

Many industries in Kansas City — including construction, transportation, warehouses, healthcare, and manufacturing — use 10-panel tests to screen for more prescription drug misuse.

A typical 10-panel can include all 5-panel drugs plus:

  • Benzodiazepines 
  • Methadone 
  • Barbiturates 
  • Propoxyphene (less common now) 
  • Methaqualone (in some variations) 

Some employers request 12- or 14-panel tests, adding drugs such as buprenorphine, tramadol, fentanyl, and synthetic cannabinoids.

 

What Types of Samples Are Used?

At Test Smartly Labs, employers can select the test method that best fits their company policy:

✔ Urine Testing (Most Common)

  • Detects drug use from 1–30 days, depending on the drug 
  • DOT-approved 
  • Fast, reliable, affordable 
  • Lab-based or instant options available 

✔ Hair Follicle Testing

  • Detects drug use up to 90 days 
  • Harder to cheat 
  • Ideal for industries wanting to eliminate long-term use 

✔ Nail Drug Testing

  • Detects up to 6 months of history 
  • Extremely reliable 
  • Great for legal cases or long-term monitoring 

✔ Oral Fluid (Saliva) Testing

  • Detects very recent use (minutes to 48 hours) 
  • Useful for on-site testing or suspicion-based situations 

Test Smartly Labs helps employers choose the correct test based on industry, compliance, and risk level.

 

What About Alcohol?

Pre-employment alcohol testing is not always required, but some companies request a breath alcohol test (BAT) or EtG urine test.

  • Breath Alcohol Test — Detects current impairment. 
  • EtG Test — Detects alcohol consumption up to 80 hours 

Employers in safety-sensitive jobs often include alcohol screening as part of onboarding.

 

Can Prescription Medications Affect the Result?

Yes — but not in the way most people assume.

If an applicant tests positive due to a legitimate prescription, the results are reviewed by a Medical Review Officer (MRO) before being released to the employer.

The MRO determines:

  • Whether the drug was legally prescribed 
  • Whether the individual is taking it as directed 
  • Whether the medication could affect job performance 

This process protects applicants while ensuring employers follow best practices.

 

How Far Back Does a Pre-Employment Drug Test Show Drug Use?

Detection times vary based on drug and test type, but here’s a general guide:

Test Type Typical Detection Window
Urine 1–30 days
Hair Up to 90 days
Nails Up to 6 months
Saliva Minutes to 48 hours

We help Kansas City employers choose the right detection window based on job duties and risk level.
