Accredited Drug Testing provides comprehensive hair follicle drug evaluations in Killeen, Texas. For those requiring hair drug or alcohol examinations, Accredited Drug Testing excels in this realm and operates testing facilities nationwide capable of carrying out hair analyses. Typically, 1.5 to 2 inches of hair from the scalp or body is necessary. The hair testing can detect drugs, alcohol/ETG, and can be tailored to specific requirements.
In recent times, hair follicle drug tests have become more prevalent in screening methods. Courts, employers, and substance abuse specialists are increasingly favoring hair analysis over traditional urine tests. Hair follicle drug tests are advantageous for employers with strict drug policies, court orders, and probationary monitoring. A key advantage is the significantly extended period of drug use detection, which can reach up to 90 days, accompanied by an observed sample collection process, making manipulation nearly impossible. However, for detecting very recent drug use, urine tests remain the gold standard.

Hair testing is now recognized as an effective instrument in identifying drug and alcohol use. The hair captures a prolonged history of these substances by embedding biomarkers within its developing fibers. When hair is taken near the scalp, it can offer a detection window of up to about three months for alcohol and other drugs. Hair collection is straightforward, relatively hard to tamper with, and easy to transport.
A hair sample measuring 1.5 inches, consisting of around 200 strands (approximately the size of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is ideal for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. It's recommended to weigh the sample on a jeweler's scale. If scalp hair cannot be obtained, an equal volume of body hair is an option. In the context of head hair, we mean only scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary).
Process Overview
Laboratory processing of a drug test involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is logged into the laboratory system. This involves ensuring the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any pending data entry not covered by an electronic chain of custody system.
Screening serves as a speedy preliminary check for drug abuse. Although Screening is a cost-efficient means to eliminate drug usage for most samples, any positive screen needs verification for legal admissibility. Samples that are presumptively positive during Screening require a follow-up confirmation.
If a sample is presumptively positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. At this stage, drugs are extracted from hair at much lower concentrations than seen in other methods like urine or oral fluid, making hair drug screening the most challenging methodology.
Confirmation for any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

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.
