FDA Clearance & CLIA Waivers: What Staffing Agencies Must Understand Before Drug Testing

Drug testing is a routine part of hiring for staffing agencies—but how those tests are sourced and administered matters more than many firms realize.

In 2026, staffing agencies are under increasing scrutiny from clients, insurers, and regulators to ensure their drug testing programs are not only fast and consistent, but also legally defensible. Two terms come up again and again in this conversation: FDA clearance and CLIA waivers.

This article explains what those terms actually mean, why they matter for staffing agencies, and how choosing the wrong testing products can create unnecessary risk.

Why FDA Clearance and CLIA Waivers Matter in Staffing

Staffing agencies operate at the intersection of speed and compliance. A screening program that slows hiring loses candidates. A program that cuts corners exposes the agency—and its clients—to liability.

FDA clearance and CLIA waivers are not marketing buzzwords. They are regulatory signals that a drug test:

• Has met specific federal standards

• Is appropriate for certain testing environments

• Can be used safely and consistently outside of a laboratory

Understanding these designations helps staffing firms choose products that support defensible, scalable drug testing programs.

What FDA Clearance Means for Drug Testing Kits

The U.S. Food and Drug Administration regulates in-vitro diagnostic devices, including drug test kits.

When a drug test is FDA-cleared, it means the manufacturer has demonstrated that the test:

• Performs as intended

• Meets accuracy and reliability standards

• Is substantially equivalent to an approved predicate device

For staffing agencies, FDA clearance is important because it:

• Signals product quality and validation

• Supports defensibility if results are challenged

• Aligns with client and insurer expectations

Using non-cleared tests may save money upfront, but it can raise questions during audits, disputes, or incident investigations.

What a CLIA Waiver Actually Means

CLIA stands for the Clinical Laboratory Improvement Amendments, which regulate laboratory testing in the United States.

A CLIA-waived drug test is classified as:

• Simple to perform

• Low risk for incorrect results

• Suitable for use outside a certified laboratory

This designation is critical for staffing agencies because it allows testing to be conducted:

• In staffing offices

• On job sites

• During onboarding events

• Without laboratory certification

In practical terms, CLIA-waived tests enable on-site, point-of-care drug testing—a major advantage for high-volume hiring.

FDA Clearance vs CLIA Waiver: They Are Not the Same

One of the most common misconceptions in staffing is assuming these terms are interchangeable. They are not.

• FDA clearance speaks to the device itself

• CLIA waiver speaks to where and how the test can be used

A staffing agency’s drug testing program works best when test kits are both FDA-cleared and CLIA-waived, ensuring quality and operational flexibility.

Why This Matters for Staffing Agencies Specifically

Staffing agencies face unique pressures:

• High candidate volume

• Tight placement timelines

• Multiple client requirements

• Varying job risk levels

Using FDA-cleared, CLIA-waived tests allows agencies to:

• Screen candidates quickly and consistently

• Reduce reliance on off-site labs

• Avoid restroom and scheduling bottlenecks

• Support same-day placements

• Maintain documentation clients trust

These benefits directly impact fill rates and client satisfaction.

Common Mistakes Staffing Agencies Make

In 2026, most drug testing problems aren’t about intent—they’re about misunderstanding.

Common issues include:

• Purchasing low-cost tests without verifying clearance status

• Assuming “rapid” automatically means CLIA-waived

• Mixing test types inconsistently across clients

• Failing to document why a test method was chosen

• Letting vendors dictate compliance instead of policy

Smart staffing agencies ask questions before buying test kits, not after a problem arises.

Urine Cups and Saliva Kits: What to Look For

Both urine and saliva drug tests can be effective for staffing—but only when properly sourced.

When evaluating kits, staffing agencies should confirm:

• FDA clearance status

• CLIA waiver designation

• Panel configuration (5, 6, 10, or 12 panel)

• Clear instructions for non-clinical staff

• Consistent lot tracking and documentation

Saliva tests are often favored for speed and observation. Urine tests remain useful for baseline screening and expanded panels. The compliance foundation matters more than the specimen type.
