ZIP groupings are a navigation aid, not a guarantee that every ZIP contains a collection clinic. Use the finder for current participating locations.
Find a Collection Clinic Near You
Enter your ZIP code to see participating Quest Diagnostics and Labcorp collection clinics anywhere in Tennessee. You choose a clinic during checkout, so confirm the provider and location before you order.
Quest Diagnostics tests must be completed at a Quest clinic, and Labcorp tests at a Labcorp clinic. Match the provider filter to the test you intend to order.
Tests Available Across Tennessee
Every lab-based test is processed through a certified laboratory partner, including Quest Diagnostics and Labcorp. Applicable tests include Medical Review Officer review and chain of custody documentation.
Urine Drug Tests
The most widely ordered specimen type, with 5 panel, 10 panel, 12 panel, expanded opiate, and DOT configurations for pre-employment, random, post-accident, and personal testing.
Hair Drug Tests
A longer look-back option than urine. Hair panels typically cover a detection window of up to about 90 days, depending on hair length and growth.
DNA and Paternity Testing
Home kits for personal knowledge, plus legal testing with photo ID verification, witnessed collection, and documented chain of custody for matters a court may review.
Nail Drug Tests
Fingernail or toenail testing can help when hair is unavailable or a longer history is requested. Detection varies with nail growth and the individual.
Oral Fluid Tests
Saliva collection focused on recent use, often used for reasonable-suspicion and post-incident workplace situations.
Alcohol Testing
Breath alcohol testing measures current impairment, while EtG and other lab options are used for monitoring over a longer period.

What Tennessee Employers and Individuals Should Know
One process across three grand divisions
A donor in Memphis, a driver based in Knoxville, and an applicant in Clarksville all follow the same steps: order the correct test online, visit a participating collection clinic, and receive results through a secure account. That consistency matters for employers with staff in more than one part of the state.
Tennessee's Drug-Free Workplace Program
Tennessee runs a state Drug-Free Workplace Program for employers. Employers who follow the program's requirements may qualify for workers' compensation premium credits. Confirm current program rules with the state and your insurance carrier before building a policy around it, and use testing panels and documentation that match the written policy.
Regulated and non-regulated testing are different orders
DOT testing for safety-sensitive transportation employees follows federal rules in 49 CFR Part 40 and uses DOT-specific panels. Non-DOT workplace testing is set by the employer's own policy. Ordering the correct category at the start avoids a recollection.
Testing across Tennessee
- Nashville-based team
- Quest Diagnostics and Labcorp collection options
- DOT and non-DOT testing
- Random testing consortium for employers
- 24/7 post-accident collection support
Employers with drivers or crews in several Tennessee cities can manage testing through one account.

How Far Back Each Test Looks
Detection windows are approximate. Actual results depend on the substance, frequency of use, dose, specimen characteristics, and individual metabolism.
| Test Type | Typical Detection Window | Commonly Used For |
|---|---|---|
| Oral fluid (saliva) | About 24 to 48 hours | Recent-use, reasonable suspicion, post-incident |
| Urine | Roughly 1 to 4 days for many substances, with variation by substance and use pattern | Pre-employment, random, DOT |
| Breath alcohol | Current impairment only | DOT alcohol testing, post-accident |
| Urine EtG (alcohol) | Up to about 80 hours | Abstinence monitoring and probation |
| Hair | Typically up to about 90 days | Longer look-back testing |
| Nail | Typically longer than hair, varying with nail growth | Extended-history situations when appropriate |

A Tennessee Company Testing Tennessee
ReliaLab Test is a third party administrator based in Nashville. The same ordering, collection, and reporting process supports individuals and employers from Memphis to the Tri-Cities.
Local support, statewide reach
The team works from 3656 Trousdale Dr, Suite 109, in Nashville, Monday through Friday. Collection happens at participating Quest Diagnostics and Labcorp clinics, so a donor does not need to travel to Nashville to test.
Employer programs built for multiple locations
Employer accounts can combine DOT and non-DOT testing, random pool management, background screening, and post-accident support. That helps Tennessee companies with crews, drivers, or offices in several counties keep one record.
Legal testing requires a legal order
For paternity and other DNA matters that a court may review, legal testing uses photo ID verification, witnessed collection, and documented chain of custody. A home kit is for personal knowledge only.
Cost follows the test, not the city
A test costs the same whether the donor is in Chattanooga or Jackson. Price depends on the specimen type and panel, and the catalog shows the price before checkout.

Tennessee Drug Testing Questions
Order the test online from ReliaLab Test, then complete collection at a participating Quest Diagnostics or Labcorp collection clinic. Clinics are available across Middle, East, and West Tennessee. Use the ZIP code finder on this page to check the nearest option before you order.
ReliaLab Test offers urine, hair, nail, oral fluid, alcohol, and DNA testing in Tennessee, along with DOT testing and background checks for employers. The correct specimen and panel depend on who requested the test and why.
Most participating collection clinics do not require an appointment, but hours and policies vary. Order first, review the instructions on your lab pass, and confirm clinic hours before you go. Legal DNA collection may need to be scheduled.
Cost depends on the specimen type and panel size, not the city. A basic urine panel, a hair panel, and a DOT test are priced differently. The online catalog shows the price for each test before checkout.
Many negative urine results reach your secure account within 24 to 48 hours after the laboratory receives the specimen. Turnaround varies by specimen type, and a non-negative screen can take longer because it goes through confirmation testing and Medical Review Officer review.
A DOT drug test follows federal rules in 49 CFR Part 40 for safety-sensitive transportation employees, such as CDL drivers regulated by FMCSA. Testing reasons include pre-employment, random, post-accident, reasonable suspicion, return-to-duty, and follow-up.
Many Tennessee employers use drug testing as part of a written workplace policy, and DOT-regulated employers must test covered employees. Employers should confirm applicable federal and state requirements, including the Tennessee Drug-Free Workplace Program if they participate, before testing.
ReliaLab Test offers home paternity kits for personal knowledge and legal paternity testing with photo ID verification, witnessed collection, and chain of custody. Legal collection can be completed at a participating collection clinic or by a mobile collector.
A standard hair test typically looks back up to about 90 days using roughly 1.5 inches of head hair. Body hair can be used when head hair is unavailable, but growth rates differ, so the window varies.
