Choose a Panel That Fits Your Testing Requirements

The right panel depends on the reason for testing and the substances that must be included. Because panel composition can vary, the selected screen should match the applicable workplace policy, regulation, or legal request.

Available screening options include:

5-panel drug test: Screens for common substances such as cocaine, marijuana, amphetamines, opiates, and phencyclidine, commonly called PCP.
10-panel drug test: Expands the screen and may include benzodiazepines, methamphetamine, and barbiturates.
Other expanded panels: Can cover additional substances, including certain synthetic drugs, when broader screening is required.

What to Expect During Collection & Result Review

A certified collector handles the specimen according to the procedures required for the selected test. Many initial results are available within minutes, while results requiring further review take longer.

The process may include:

Specimen collection: We collect and identify the sample according to the applicable testing procedure.
Initial screening: We screen the specimen for the substances included in the selected panel.
Laboratory confirmation: A positive or non-negative initial result may require laboratory confirmation. This additional step can take one to three days.

DOT & Non-DOT Urine Testing for Fort Worth Employers

We support DOT-compliant programs and non-DOT workplace screening. The appropriate panel and collection procedure depend on whether the employee holds a federally regulated, safety-sensitive position.

Employers should understand these distinctions:

DOT testing: Federal rules require a standardized 5-panel urine screen and collection procedures established under 49 CFR Part 40. A Medical Review Officer, a licensed physician responsible for reviewing laboratory findings, verifies results through the federal process.
Non-DOT testing: Employers generally have more flexibility to set the testing frequency, panel size, and substances screened through their workplace policy, subject to applicable laws.

Chain-of-Custody Testing for Tarrant County Legal Matters

For collections that require legal defensibility, we follow chain-of-custody procedures. This documented record identifies who collected, handled, transferred, and tested the specimen from collection through reporting.

Our collectors regularly work with attorneys, judges, and individuals who need court-admissible results. This documentation may be required for probation, custody matters, pending drug-related cases, or attorney-directed testing in Tarrant County. The panel and testing method should follow the instructions provided by the court, supervising agency, or attorney.

How Detection Windows & Validity Checks Affect Results

Many drugs remain detectable in urine for approximately two to 10 days after use, but no single detection window applies to every sample. The substance, frequency of use, metabolism, hydration, and other factors can affect how long a drug or its metabolites remain detectable.

How We Check for Dilution or Tampering

Our testing protocol includes specimen validity checks that can flag diluted, substituted, or adulterated samples. An adulterated sample contains a substance added to interfere with testing. These checks commonly evaluate temperature, pH, specific gravity, and creatinine levels.
