Accredited Drug Testing provides extensive hair follicle drug assessments in Johnson City, Texas. Whether you need a hair drug or alcohol evaluation, we specialize in hair testing and have facilities in all cities nationwide to facilitate your test. Typically, a length of 1.5 to 2 inches of hair from the crown or body suffices. These tests check for drugs, alcohol/ETG, or offer tailored testing solutions.
Over the years, drug testing methods have increasingly leaned towards hair follicle drug tests. Employers, judicial systems, and Substance Abuse professionals now favor hair over urine tests. Used by organizations with strict no-drug policies, courts, and probation services, hair follicle tests identify drug use over extended periods, up to 90 days. However, for detecting recent drug use, within 5 days, urine tests remain the most precise option.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

The detection of drug and alcohol ingestion through hair testing is increasingly regarded as an effective approach. Hair records a comprehensive history of substance use, capturing biomarkers within the strands of developing hair. When collected near the scalp, hair provides an extended detection period of up to three months for alcohol and drugs. It's straightforward to collect, resistant to tampering, and convenient to transport.
Gathering a segment of hair approximately 1.5 inches in length, containing around 200 strands (similar in size to a #2 pencil), yields 100mg of hair, which is the optimal quantity for analysis and verification. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It’s advised to measure the sample on a jeweler’s scale. If head hair is not accessible, an equivalent amount of body hair may be used. 'Head hair' refers solely to scalp hair, whereas 'body hair' encompasses all other types of hair (including facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into a laboratory’s framework. This step includes verifying the integrity and proper shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.
Screening is a preliminary assessment to identify potential drug usage. Though Screening efficiently rules out drug use in most cases, a positive result requires confirmation to be valid in a legal context. Samples that are tentatively positive in Screening necessitate additional confirmation.
For samples tentatively positive in the Screening stage, extra hair is extracted from the initial sample for the Extraction phase. During this phase, drugs are isolated from hair at concentrations significantly lower than those in other sample types (e.g., urine or oral fluid), making hair drug screening the most challenging to execute.
Positive Screening results undergo confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation if necessary. The comprehensive laboratory procedure, from Accessioning to Confirmation, is evaluated based on the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
