Accredited Drug Testing conducts comprehensive hair follicle drug tests in Hills Prairie, Texas. For those requiring a hair drug or alcohol analysis, we specialize in this testing type, with centers across all U.S. cities. Typically, 1.5 to 2 inches of hair from the crown or body is required. Hair analyses may include drug detection, alcohol/ETG, or can be customized for specific hair tests.
Lately, hair follicle drug testing has become a more common method for detecting drug use. Many employers, judicial systems, and substance abuse experts now prefer hair testing over traditional urine tests. This method benefits employers enforcing strict drug policies and judicial entities with its extended detection period of up to 90 days, non-tamper collection, and difficulty to alter results. However, urine tests remain more precise for recent substance use within a 5-day window.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term record for alcohol and drugs, capturing biomarkers within the hair strands as they grow. By collecting hair near the scalp, a detection range of up to roughly three months for alcohol and drugs is achievable. Hair is easy to collect, moderately challenging to tamper with, and straightforward to transport.
A sample of 1.5 inches consisting of around 200 hair strands (approximately the thickness of a #2 pencil) near the scalp provides 100mg of hair, which is the perfect sample size for analysis and verification. For EtG, supplementary tests, and/or assessments beyond 10 panels, it's advised to use 150mg of the sample. It's advisable to use a jeweler’s scale to weigh the sample. If scalp hair is not available, a similar amount of body hair can be used. Head hair specifically refers to hair from the scalp. Body hair includes all other hair forms (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is processed into the lab’s system. This step verifies that the sample is properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data required not captured by an electronic chain of custody system.
Screening is a preliminary evaluation for substances of abuse. Although Screening is an economical approach to exclude drug use in most samples, a positive result requires confirmation to be legally valid. All samples that show a presumptive positive in Screening necessitate secondary validation.
When a specimen is presumptively positive at the Screening stage, additional hair is extracted from the primary sample for the Extraction phase. Here, drugs are extracted from hair at a lower concentration than other methods (e.g., urine or saliva), which makes hair drug analysis the most challenging method to execute.
Verification of any positive screen outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample is washed before confirmation if necessary. The complete laboratory procedure from Accessioning to Verification is audited under both the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the examination itself targets the hair strand and not the follicle beneath the scalp.

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.
