In Vidaurri, Texas, Accredited Drug Testing offers comprehensive hair follicle testing for drugs and alcohol. Specializing in hair assessments, our nationwide centers are equipped to conduct these tests across all cities. Generally, 1.5 to 2 inches of hair from the crown or body is required. Tests can measure drugs, alcohol/ETG, or provide tailored options.
Recently, hair follicle drug tests have become more common for drug screening. Employers, courts, and substance abuse counselors often prefer hair tests over urine tests. Hair tests are favored by those enforcing no-tolerance policies, courts, and probationers due to their longer detection span of up to 90 days, the observed collection method, and the difficulty of tampering. Nonetheless, for screening recent drug use within 5 days, urine tests remain the most accurate.

The use of hair tests has become recognized as an effective method for identifying the usage of drugs and alcohol. Hair captures biomarkers within its fibers, offering an extended history of substance consumption. When hair is gathered near the scalp, it can reveal a detection period of up to around three months for alcohol and drugs. The collection of hair is straightforward, posing challenges to tampering, and is efficiently shipped.
A segment measuring 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil’s size) located near the scalp provides around 100mg, which is the preferred sample mass for both screening and confirmation processes. For tests such as EtG, additional panels, or any test exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for measuring the sample. In scenarios lacking scalp hair, a similar quantity of body hair is an acceptable alternative. In this context, head hair indicates specifically scalp hair, while body hair encompasses all other forms (including facial, axillary, etc.).
Process Overview
The lab processing of a drug test outcome encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial management of a specimen within the laboratory framework. It entails verifying the intact seal and proper shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data input which isn’t covered by an electronic chain of custody setup.
Screening offers a preliminary rapid assessment for substances of abuse. While Screening provides a cost-efficient solution for excluding drug usage in most samples, favorable screens require confirmation to be valid in legal settings. Samples that indicate potential positivity during Screening must undergo secondary validation.
Upon a positive indication during the Screening stage, further hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations than alternative approaches (such as urine or oral fluid), making hair drug screening the most challenging technique to execute.
Subsequent Confirmation of any positive results is performed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All preliminarily positive samples are subject to washing before confirmation when needed. The comprehensive laboratory procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair guidelines and accreditation to ISO / IEC 17025 standards.

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.
