In Smithland, Texas, Accredited Drug Testing provides comprehensive hair follicle drug testing services. If you require a hair or alcohol test, they specialize in hair testing with centers available nationwide, ready to conduct these tests. Generally, 1.5 to 2 inches of hair is needed from the crown or other body parts. Hair testing can reveal drugs, alcohol/ETG, or other tailored testing options.
Recently, hair follicle drug testing has become a favored method for substance screening over the standard urine test. It's popular among employers with strict no-drug policies, court systems, and probation services. The key advantage is its extended detection window—up to 90 days—making it nearly foolproof compared to other methods. However, for identifying very recent drug use, a urine test remains more precise.

Hair analysis is increasingly regarded as an effective method for detecting substance and alcohol usage. Hair holds a comprehensive timeline of alcohol and drug activity by embedding biomarkers within the growing strands. When gathered from the scalp, it can reveal substance presence over an estimated three-month duration. The collection process is straightforward, with challenges in tampering, and it's convenient for transport.
A sample measuring 1.5 inches, containing roughly 200 hair strands (about #2 pencil thickness) nearest to the scalp yields 100mg, an optimal amount for screening and validation. For EtG, additional tests, or more than 10-panel tests, 150mg is advised. It's best to measure using a jeweler's scale. When scalp hair isn’t available, an equivalent quantity of body hair can be used. In terms of head hair, we mean scalp hair alone. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The principal steps in lab analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about processing a sample into a lab's system, checking that it was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry outside of an electronic chain of custody system.
Screening provides a rapid check for drugs of abuse. While it is an economical way to eliminate drug use in most samples, a positive result must be confirmed for legal admissibility. Samples showing presumptive positives in Screening need subsequent confirmation.
Should a sample show a presumptive positive in Screening, additional hair is collected from the initial sample for Extraction. Here, drugs are extracted from hair at lower concentrations than other methods (e.g., urine or oral fluid), making hair testing the most challenging method.
Confirmation of positive results occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to necessary confirmation. The lab process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often termed "hair follicle tests," the analysis focuses on the hair strand, not the follicle beneath the scalp.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. 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.
