In Valera, Texas, Accredited Drug Testing offers comprehensive hair follicle drug tests. If you require a hair or alcohol test, our expertise lies in hair testing, with centers across all U.S. cities ready to conduct these tests. Generally, 1.5 to 2 inches of hair from your head or body is needed. The tests can screen for drugs, alcohol/ETG, or be tailored for other specific hair testing requirements.
Over the years, hair follicle tests have increasingly been used for drug screenings. Employers, courts, and substance abuse professionals lean towards hair tests instead of the usual urine tests. Companies with zero-tolerance drug policies, judicial systems, and probation clients often prefer this method. Its main advantage is the longer detection window, typically up to 90 days, collected under supervision, making it hard to manipulate. Nonetheless, for detecting drug use within the last 5 days, urine tests remain the most precise.

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Through capturing biomarkers within the fibers of the growing hair strand, hair offers a comprehensive overview of alcohol and drug usage over time. When taken from near the scalp, hair can offer up to a 90-day detection period for alcohol and drugs. Hair is effortless to collect, presents a challenge to tamper with, and is simple to transport.
A sample measuring 1.5 inches of roughly 200 hair strands (about the size of a #2 pencil) nearest to the scalp will yield 100mg, deemed the optimal sample size for screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a specimen size of 150mg is advised. We suggest measuring the specimen using a jeweler’s scale. Should scalp hair not be accessible, an equivalent quantity of body hair can be gathered. By head hair, we mean scalp hair specifically. Body hair encompasses all other hair types (like facial or axillary).
Process Overview
The lab processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary integration of a sample into the lab’s system, ensuring the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any leftover data entry absent from an electronic chain of custody system.
Screening consists of an initial rapid assessment for drugs of abuse. Although Screening serves as a cost-efficient means to clear most samples of drug use, a positive outcome necessitates confirmation to be court-acceptable. Presumptively positive samples at the Screening stage require additional verification.
If a sample appears presumptively positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. In Extraction, drugs are retrieved from hair at a much lower concentration than other methods (like urine or oral fluid), making hair drug analysis the most challenging method to execute.
Confirmation of any positive screening result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives receive a wash before confirmation if needed. The complete lab process from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair directive and the accreditation to ISO / IEC 17025 standards.

Note: Often labeled as "hair follicle tests", the analysis targets the hair strand rather than the follicle below 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.
