In Crockett, Texas, Accredited Drug Testing offers comprehensive hair follicle drug testing. For those needing a hair drug or alcohol test, our expertise lies in hair testing, with centers available in all cities nationwide. Typically, 1.5 to 2 inches of hair is required from the head or body. Our hair tests can identify drugs, alcohol/ETG, and provide other custom hair testing solutions.
Recently, methods for conducting drug tests have increasingly included hair follicle tests. Many employers, courts, and substance abuse professionals now prefer hair tests to standard urine tests. Hair follicle testing is favored by employers with zero-tolerance policies, courts, and probation-supervised individuals. Its key advantage is a 90-day detection window, observed during collection, making it nearly cheat-proof. Yet, urine remains best for recent-use screening within 5 days.

Hair analysis is increasingly recognized as a valuable resource for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and drug exposure by encapsulating biomarkers within the existing hair strand fibers. When sourced near the scalp, hair samples can reveal a detection timeframe of up to three months for alcohol and drugs. The collection of hair is straightforward, relatively tamper-resistant, and facilitates easy transportation.
A sample of 1.5 inches, consisting of around 200 hair strands (equivalent in thickness to a #2 pencil) nearest to the scalp, results in 100mg of hair, which is the optimal quantity for analysis and verification. For EtG, additional tests, and extensive panels exceeding 10, a specimen of 150mg is advisable. It is suggested that specimens are measured using a jeweler’s scale. If scalp hair is unobtainable, a commensurate quantity of body hair may be used. "Head hair" pertains solely to scalp hair, whereas "body hair" encompasses all other hair types, such as beard and underarm hair.
Process Overview
The fundamental phases in laboratory processing for drug test evaluation include Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the first processing step where a sample is systematically registered. This phase ensures that samples are properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and addresses any data entry omissions from an electronic custody system.
Screening provides an initial rapid assessment for illicit drugs. Although Screening presents a cost-effective method to exclude drug use in most samples, any findings from a positive screen must undergo confirmation for legal acceptability. Any samples testing presumptively positive in Screening require a secondary verification.
Upon a presumptive positive in Screening, excess hair is extracted from the original sample for the Extraction phase. During this phase, drugs are drawn from hair at lower concentrations than found in alternative methodologies like urine or oral fluid, underscoring the complexity of hair drug testing.
Confirmation for positive Screening outcomes is completed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all presumptive positive samples are cleaned as necessary. The entire process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and accredited according to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though often termed as "hair follicle tests", the examination actually involves the hair strand above the scalp, not the follicle itself.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed.
