Accredited Drug Testing provides comprehensive hair follicle drug testing services in Agua Dulce, Texas. Specializing in hair testing, our facilities nationwide can conduct both drug and alcohol hair tests. A hair length of 1.5 to 2 inches is typically required, though body hair can also be used. Custom tests for drugs, alcohol/ETG, and other substances are available.
In recent times, hair follicle drug tests have become a preferred method for drug screening. Many organizations, including employers, courts, and Substance Abuse professionals, now opt for this test over the traditional urine test. This method is favored by those enforcing zero-tolerance drug policies due to its extended detection window, which can be up to 90 days. Collecting the sample under observation also reduces the possibility of tampering. However, for drug use within the past five days, a urine test remains more precise.

Hair analysis is recognized as a robust method for identifying drug and alcohol usage. Hair captures a comprehensive history of alcohol and other drugs by embedding biomarkers within the hair strand as it grows. When the sample is taken near the scalp, it offers up to a 3-month detection timeframe for alcohol and other drugs. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.
A sample section measuring 1.5 inches, consisting of approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is the optimal quantity for testing and verification. For tests like EtG, additional panels, or more than 10-panel screens, 150mg of the sample is suggested. Using a jeweler’s scale to weigh the sample is advised. If scalp hair is not present, a similar amount of body hair can be utilized. "Head hair" refers solely to scalp hair, whereas "body hair" encompasses other hair forms (such as facial or underarm hair).
Process Overview
Processing a drug test result in the lab involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is logged into the lab's system. This includes checking that the sample was properly sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and completing required data entry aside from what an electronic chain of custody system provides.
Screening provides a preliminary check for drug use. It serves as a cost-efficient means to rule out drug consumption in most samples, though a positive result in screening must be validated for court acceptability. Any samples that are presumptively positive in Screening require a follow-up confirmation.
Should a sample be presumptively positive during Screening, additional hair is extracted from the initial collection for further processing in Extraction. This stage involves isolating drugs from hair at lower concentrations than other methods (such as urine or oral fluid), explaining why hair drug screening is among the most challenging methodologies.
Verification of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed as needed before confirmation. The comprehensive lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though often called "hair follicle tests", these tests analyze the hair strand instead of the follicle beneath the scalp.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
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. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
