In Brenham, Texas, Accredited Drug Testing provides comprehensive hair follicle drug screenings. If you require a hair drug or alcohol assessment, our specialization lies in this area and we have facilities nationwide to conduct such tests. Typically, samples require 1.5 to 2 inches of hair from the crown or body. These tests can detect drugs, alcohol/ETG, or be customized for other analyses.
The trend for drug screenings has shifted towards hair follicle testing. Employers, courts, and substance abuse experts often prefer it over urine testing. Businesses with zero-tolerance policies, judicial systems, and probation services utilize hair tests. This method's advantage is a 90-day detection period, observed collections, and resistance to tampering. However, urine tests are more accurate for recent use within 5 days.

Hair examinations have emerged as a potent method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and other substances by embedding biomarkers within the strands of hair as it grows. When cut close to the scalp, hair offers a detection window of up to roughly three months for alcohol and drugs. It's straightforward to collect, somewhat challenging to tamper with, and conveniently transportable.
A sample measuring 1.5 inches, consisting of approximately 200 strands of hair (comparable to the thickness of a #2 pencil) near the scalp, will yield 100mg of hair, which is the preferred sample size for testing and confirmation. For EtG, expanded panels, and/or examinations exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing the specimen. Should scalp hair be inaccessible, a similar quantity of body hair can be gathered. By head hair, we mean scalp hair exclusively. Body hair pertains to every other hair type (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary handling of a sample within a laboratory’s framework. This step verifies the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry absent in an electronic chain of custody system.
Screening entails a rapid preliminary evaluation for drugs of abuse. While Screening is an economical strategy to eliminate drug usage in most samples, a positive result from Screening requires confirmation to be court-admissible. Any sample presumptively positive in Screening mandates secondary confirmation.
When a sample is presumptively positive in the Screening phase, an additional quantity of hair is extracted from the initial sample and readied for Extraction. This stage extracts drugs from hair at significantly lower concentrations compared to other methods (for example, urine or oral fluid), which makes hair drug screening one of the most challenging methodologies.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Washing of all presumptive positive samples is done prior to confirmation as required. Each part of the laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although frequently called "hair follicle tests", the test examines the hair strand itself rather than the hair 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
