Accredited Drug Testing offers comprehensive hair follicle testing services in Clarendon, Texas. Should you require a hair or alcohol test, we excel in the field of hair tests, with nationwide testing centers ready to assist. Typically, 1.5 to 2 inches of hair from the head or body is required. Hair testing provides analysis for drugs, alcohol/ETG, or custom options.
Recently, there has been an increase in the implementation of hair follicle drug testing. Employers, courts, and substance abuse experts are often choosing hair drug tests over traditional urine tests. This method is preferred among those enforcing zero-tolerance policies. The advantage of hair testing is its extended detection window—up to 90 days—collected under supervision and nearly impossible to tamper with. However, for detecting recent drug use within 5 days, urine tests remain the most precise.

Hair testing has emerged as a formidable method for uncovering drug and alcohol consumption. Hair retains a detailed record of alcohol and drug usage by encapsulating biomarkers in the fibers of the hair strand as it grows. When gathered near the scalp, hair offers roughly a 3-month period during which it can detect alcohol and drug use. Hair is easy to collect, relatively hard to tamper with, and simple to send.
A sample measuring 1.5 inches with approximately 200 hair strands (equivalent to the width of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal specimen for both screening and confirmation. For EtG tests, additional panels, and those exceeding 10 panels, 150mg of hair is advised. It's recommended to use a jeweler’s scale for weighing the sample. If scalp hair is inaccessible, a corresponding amount of body hair may be obtained. When mentioning head hair, it strictly pertains to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
A drug test result's laboratory processing encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating the initial sample into a laboratory’s framework. This step ensures the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplemental data entry not covered by an electronic chain of custody system.
Screening conducts a preliminary rapid check for drug abuse. Although Screening is a cost-efficient means of eliminating drug use in most samples, a positive screen demands confirmation to be permissible in legal settings. Any samples that test presumptively positive in Screening necessitate a secondary confirmation.
If a sample is flagged as presumptively positive during Screening, more hair is extracted from the initial sample and set up for Extraction. During this phase, drugs are extracted from hair at lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to execute.
Confirmation of screened positive results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed prior to confirmation if needed. The entire laboratory process, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Note: Although often called "hair follicle tests", the analysis is performed on the hair strand and 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
