In Votaw, Texas, Accredited Drug Testing delivers comprehensive hair follicle drug testing solutions. Our facilities across the nation conduct hair drug or alcohol testing, requiring 1.5 to 2 inches of hair from the head or body in most instances. Hair tests can detect drugs, alcohol/ETG, or custom options.
Recently, hair follicle drug testing has become a preferred method for determining drug use. Employers, courts, and Substance Abuse professionals often choose this method over standard urine tests due to its extended detection period of up to 90 days. It's almost impossible to tamper with, offering a reliable alternative for those with zero-tolerance policies. However, a urine test is more effective for identifying drug use in the past 5 days.

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. The fibers of growing hair strands trap biomarkers, offering an extended record of substance use. When sampled close to the scalp, hair can reveal usage of alcohol and drugs for a period of up to roughly three months. Hair collection is straightforward, relatively resistant to tampering, and easily shipped.
A 1.5-inch hair sample containing around 200 strands (similar in size to a #2 pencil) gathered near the scalp provides an approximate weight of 100mg, ideal for screening and confirmation processes. For EtG analyses, additional testing, or examinations that exceed 10 panels, a specimen weight of 150mg is advisable. It's suggested to measure the sample using a jeweler’s scale. In instances where scalp hair is not available, a similar quantity of body hair may be used. The term head hair specifically refers to scalp hair, whereas body hair includes all other hair types (such as facial or axillary).
Process Overview
The drug test result laboratory process consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the laboratory system. This step includes ensuring that the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any remaining data entry that was not included by an electronic chain of custody system.
Screening serves as a preliminary technique to detect drug usage. While Screening is an economical approach to eliminate drug use in most samples, a positive result requires confirmation for legal validity. Any samples deemed presumptively positive in Screening need subsequent confirmation.
In cases where Screening indicates a presumptive positive, additional hair is extracted from the original sample for further preparation in the Extraction process. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug analysis a particularly challenging methodology.
Confirmation of positive Screening results is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as required before confirmation. The entire laboratory procedure, from Accessioning through Confirmation, is conducted in compliance with the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although sometimes labeled as "hair follicle tests", the analysis targets the hair strand, not the hair 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.
