The Cobb County Drug Screening Lab is an independent, on-site laboratory, specializing in providing comprehensive and quality testing service for the Cobb County judicial complex and support agencies.

This on-site drug and alcohol testing laboratory was opened on the judicial campus during 2007 to reduce the cost of testing and to provide immediate testing results to court services and ensure public safety. The laboratory collects the donor’s specimen and provides the ordering agency with immediate analysis result. All specimen collections are directly observed to provide the most effective approach to the prevention of adulteration and substitution. The Drug Screening Lab provides time saving, economical, and accurate point of collection analysis, while maintaining the highest compliance with professional testing standards. As an added convenience to customers, the Lab accepts credit card/debit payments.

*In addition to the payment being rendered, a federal or state issued ID must be presented prior to being screened.

Processes and Procedures

Once payment has been collected, the individual will sit outside in the waiting room to be called. Your state or federal issued ID will be held until the screen is collected for identification purposes.

NOTE: Before any screen can be conducted, a review of the drug screen procedures must be reviewed. 

Judicial Interpreters

Interpreter Request Form

The Cobb County Judicial Interpreters Program, administered by Superior Court Administration, provides interpreters to protect the rights of limited English proficiency individuals under the Title VI Civil Rights Act of 1964 and deaf or hard of hearing individuals under the Americans with Disabilities Act and state law (O.C.G.A. §24-6-650 to 658). While Spanish is the most requested language, we do get requests for dialects such as Amharic.

In any case, it is our procedure to diligently attempt to secure a certified interpreter first. If one is not available, we try for a registered or conditionally approved interpreter. If that effort fails, the judge will follow the Supreme Court of Georgia Commission on Interpreters guidelines to qualify the interpreter from the bench.

With Atlanta’s increasingly diverse population, the need for interpreters has grown dramatically. When the program started in 1990 there were 36 requests for interpreters. By 2017, the requests had increased to 4,256 for the year.

The Cobb County Judicial Interpreters Program maintains a list of interpreters certified or registered with the Georgia Commission on Interpreters. For information on how to become a certified or registered court interpreter visit

Permanent Process Servers

A Process Server must have an Order from Court each time he or she is to serve papers. Beginning in 1998, Cobb County Superior Court Judges elected to start a program enabling Process Servers to receive a standing Order for an entire year instead of requiring a new order each time personal service is required. To become a new Permanent Process Server in Cobb County, a person must complete an application and have it endorsed by a Cobb attorney in good standing. Previously approved Process Servers must complete a renewal application package annually. After a criminal background check is completed, an Order is signed to award Permanent Process Server status for one year.
