Introduction to 5 and 10-Panel Drug Testing

Employers, schools, and government organizations use drug tests to screen individuals for illegal or controlled substances. People who are conscious of their health can even book them independently.

Both 5-panel and 10-panel drug tests serve as critical tools for pre-employment screening, routine workplace testing, and recovery monitoring. These tests not only help prevent workplace accidents but also ensure that organizations comply with federal and industry-specific regulations.

PART I: The 10-Panel Drug Test

10-Panel Drug Testing Overview

What is the Purpose of a 10-Panel Drug Test?

A 10-panel drug test is designed to identify ten specific substances, providing a comprehensive snapshot of an individual’s recent drug use. Employers, healthcare providers, and legal authorities (such as the Department of Transportation – DOT) frequently use this test for the following reasons:

  • Workplace Safety and Compliance: Maintaining a drug-free workplace prevents accidents and supports productivity. This is especially crucial in industries involving machinery or public interaction.
  • Regulatory Compliance: Compliance with industry-specific guidelines, such as those in transportation, construction, and healthcare, is often mandated by law.
  • Substance Abuse Monitoring: Used in recovery programs, a 10-panel drug test tracks an individual’s progress and adherence to sobriety.
  • Controlled Substances Detection: Analytical toxicology examines samples for drug residues and controlled substances that may affect work performance or safety.

The test is also part of pre-employment drug screenings to prevent substance abuse issues before they become workplace concerns. Background checks combined with drug testing offer a holistic approach to ensuring safe hiring practices.

What are the Substances Detected?

The 10-panel drug test screens for the following substances, covering both illegal drugs and prescription medications that may be misused:

Amphetamines and Methamphetamine

Often used illicitly, these substances can lead to aggressive behavior and impaired decision-making.

Barbiturates and Benzodiazepines

Prescribed for anxiety and sleep disorders but may lead to misuse.

Cocaine

A highly addictive stimulant with severe health consequences.

Marijuana (THC) and THC Oil

Although marijuana is legal in some states, many employers still test for it due to its psychoactive effects.

Methadone

Used in opioid addiction treatment but can be misused.

Opiates and Opioids

Includes drugs like heroin and prescription painkillers.

Phencyclidine (PCP)

Known for causing hallucinations and violent behavior.

Phenobarbital and Propoxyphene

Prescription medications that can be dangerous if misused.

Detection Times

Detection times, or windows, vary based on the drug, the individual’s metabolism, and the type of test:

  • Urine Tests: Most common. Urine tests offer detection times of a few days to weeks for different drugs.
  • Saliva Tests: Shorter detection windows. Saliva tests typically provide results within hours to a few days.
  • Blood Tests: More invasive, detecting drugs taken within hours or days. PEth alcohol tests are a popular subcategory.
  • Hair Tests: Provide the longest detection window, potentially showing drug use over the past 90 days.
  • Fingernail Tests: Very accurate. These test for a wide range of substances over a lengthy period.

Factors affecting detection include the individual’s hydration level, drug purity, and metabolism rate. Drug metabolites, the byproducts of substances broken down in the body, are the primary indicators in these tests.

Testing Procedure

The 10-panel drug testing process includes several steps:

Preparation

Instructions may include fasting or avoiding certain medications.

Sample Collection

Urine is the standard sample type, collected under controlled conditions to prevent tampering.

Sample Analysis

The sample is shipped to a certified lab, where it undergoes urinalysis and further analysis for drug metabolites.

Results Review

A Medical Review Officer (MRO) reviews and confirms results, especially if non-negative.

Interpreting Results

Drug test results interpretation representation.

Drug test results are usually categorized as follows:

  • Negative: Indicates no drug presence above the cut-off concentration.
  • Positive: Drug levels exceed the acceptable threshold.
  • Inconclusive or Invalid: Requires a retest due to contamination or abnormal pH levels.

False positives can occur, often due to prescription drugs or over-the-counter medications. Confirmatory tests like gas chromatography-mass spectrometry (GC-MS) help verify positive results.

Handling Positive Results

If the test results are positive, a certified MRO will contact the test-taker to discuss any legitimate prescription use. A second lab test can confirm the results, especially in cases of potential false positives.

Legal and Workplace Considerations

A judge's hammer.

Employers in Portland, Oregon State, and across the US must comply with federal laws, such as:

Americans with Disabilities Act (ADA)

The ADA prohibits employment discrimination based on disability, which includes protections for individuals with a history of substance abuse who are in recovery or undergoing treatment. However, it does not protect current illegal drug users.

Under the ADA, employers must make reasonable accommodations for qualified individuals in recovery as long as it does not pose a direct threat to workplace safety. This law ensures that employees are not discriminated against solely for past substance use or addiction treatment.

Drug-Free Workplace Act of 1988

This federal law requires certain employers, particularly those with federal contracts or grants, to establish and maintain a drug-free workplace. It mandates that these employers implement drug-free policies, conduct employee drug awareness programs, and take corrective action if employees engage in drug-related misconduct.

Although the act does not require employee drug testing, it encourages employers to create a workplace free from illegal drug use to comply with federal regulations.

Title VII of the Civil Rights Act

Title VII prohibits employment discrimination based on race, color, religion, sex, or national origin.

In the context of drug testing, Title VII requires that drug testing policies be applied fairly and consistently to all employees without discriminatory intent or impact. Employers must ensure that testing does not disproportionately target certain groups and must accommodate religious practices where possible, so long as it does not interfere with legitimate safety concerns.

Fair Credit Reporting Act (FCRA)

The FCRA regulates how employers use background checks, including drug test reports, in employment decisions. It mandates that employers must inform and obtain written consent from applicants or employees before conducting a background check or drug test through a third-party service.

If a test yields unfavorable results that may impact employment, the FCRA requires the employer to provide a copy of the report and a summary of rights before taking adverse action, ensuring transparency and fairness in employment decisions.

Family and Medical Leave Act (FMLA)

The FMLA provides eligible employees with up to 12 weeks of unpaid, job-protected leave for specific family and medical reasons, including treatment for serious health conditions, which could include substance abuse treatment. However, FMLA protections do not extend to absences due to substance abuse itself, only to leave for treatment, thereby supporting employees in seeking recovery without the fear of job loss.

National Labor Relations Act (NLRA)

The NLRA protects employees’ rights to collective bargaining and concerted activities. When it comes to drug testing policies, employers in unionized workplaces must negotiate drug testing procedures with the union. Even in non-union settings, the NLRA allows employees to discuss and address concerns about drug testing policies collectively, ensuring that employees have a voice in workplace decisions that impact them.

Post-Incident Evaluations

Post-incident evaluations are drug tests conducted after a workplace accident or incident, especially if the incident resulted in injury or property damage. The goal is to determine whether drug or alcohol use may have been a contributing factor. This type of evaluation helps employers maintain a safe workplace by identifying substance abuse issues that could lead to recurring safety hazards.

Random Testing

Random testing involves selecting employees at random for drug testing, often as part of an ongoing program to discourage drug use and promote workplace safety. It is commonly used in safety-sensitive industries, such as transportation and construction, and is often mandated by federal regulations for certain roles. The screening must be conducted impartially and consistently to comply with employment law.

State Laws

Drug testing laws vary significantly by state, and employers must comply with specific state regulations regarding how and when drug testing can be performed. Some states have strict guidelines on drug testing practices, including conditions for pre-employment, post-incident, and random testing and restrictions on testing for substances like marijuana, which is legal in some states.

Employers should be familiar with state laws to ensure compliance and to respect employee rights under local jurisdiction.

Part II: The 5-Panel Drug Test

5-Panel Drug Test Overview.

Purpose and Substances Tested

The 5-panel drug test is a simpler version commonly used by employers and federal agencies. It screens for five substances:

  1. Amphetamines
  2. Cocaine
  3. Opiates
  4. Phencyclidine (PCP)
  5. Marijuana (THC)

The Department of Transportation (DOT) mandates 5-panel testing for its employees, and it’s the standard in most federal workplace guidelines.

Detection Timeframes

The 5-panel test primarily uses urine samples, but detection times vary depending on sample type.

Chronic users may have longer detection times due to metabolite build-up in their system.

Test Procedure and Preparation

Preparation for a 5-panel test generally involves avoiding certain medications. The sample collection is straightforward, followed by analysis at a lab. Results are typically delivered within days.

Understanding Test Results

Results interpretation includes:

  • Negative: No drug traces above the cut-off.
  • Positive: Drug levels exceed the threshold.
  • Inconclusive: Possible errors requiring a retest.

As with 10-Panel Testing, the MRO reviews and confirms non-negative results. Prescription drug verification can explain some non-negative results.

Drug Testing Laws

Drug testing regulations enforced in the US and Oregon State.

Federal laws, including the Civil Rights Act and ADA, govern workplace drug testing practices. Oregon’s state-specific cannabis laws may impact THC testing restrictions, especially where marijuana is legal. Employers should be aware of these regulations to avoid discrimination lawsuits.

Employer and Employee Considerations

Results are confidential and shared directly with the employer. For a positive result, the employee may face disciplinary action, depending on company policies and whether the result stems from prescribed medications.

Additional Testing Options

Other options beyond the 5 and 10-panel tests include:

  • 4-Panel Tests: Excludes certain drugs like marijuana.
  • 7-Panel Tests: Additional prescription drugs.
  • Non-DOT Tests: Customized for private companies.

Employers may opt for DOT-certified or standards-upholding labs like ours 🤓 or work with MROs to ensure the integrity of the testing process.
