In Weslaco, Texas, Accredited Drug Testing offers comprehensive hair follicle drug assessments. For those seeking hair-based drug or alcohol screening, our expertise lies in hair follicle testing, available at centers across the nation. Typically, 1.5 to 2 inches of hair from the crown or body is sufficient for testing. Hair samples can be scrutinized for drugs, alcohol/ETG, or other tailored hair analysis options.
Recent trends show an increase in the use of hair follicle drug assessments for substance detection. Employers, judicial bodies, and Substance Abuse experts favor hair tests over traditional urine tests. Hair follicle assessments are optimal for organizations implementing strict drug policies, the judiciary, and probationary monitoring. The advantage lies in an extended detection window, often up to 90 days, with the collection process being difficult to tamper with. Nevertheless, for detecting drug use within the immediate past 5 days, urine tests remain more reliable.

Hair analysis is recognized as a vital method for identifying drug and alcohol consumption. By capturing biomarkers in the fibers of the growing hair, it offers a comprehensive history of substance use. A sample collected close to the scalp can reveal drug and alcohol use over the past three months. Hair collection is straightforward, resistant to tampering, and convenient to transport.
A 1.5-inch segment of approximately 200 hairs (comparable to the girth of a #2 pencil) nearest to the scalp yields 100mg, the perfect amount for both screening and validation. For EtG, add-on tests, or those exceeding 10 panels, 150mg of hair is suggested. Using a jeweler’s scale to weigh the sample is advisable. In the absence of scalp hair, an equivalent amount of body hair may be taken. The term "head hair" specifically refers to the scalp, whereas "body hair" encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory processing for a drug test encompasses four major phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts by incorporating a sample into the laboratory’s system, ensuring proper sealing and shipment, determining a random LAN (Laboratory Accessioning Number), and filling in any missing data not provided by an electronic chain of custody system.
Screening is a preliminary examination for drugs of abuse. Although it's a cost-effective approach for detecting drug absence in most samples, a positive outcome in Screening must be validated for legal proceedings. A secondary confirmation is necessary for screened presumptive positive samples.
Should Screening indicate a presumptively positive sample, additional hair is taken from the original sample for the Extraction process. Here, drugs are extracted from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluids), contributing to hair drug screening being the most challenging technique to execute.
Confirmation of any positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as needed. The comprehensive laboratory process from Accessioning to Confirmation is vetted under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Note: While termed "hair follicle tests," the analysis focuses on the hair strand rather than the follicle beneath the scalp.

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.
