Accredited Drug Testing offers comprehensive hair follicle drug testing services in Lakeway, TX. If you're in need of a hair drug or alcohol test, count on our expertise in hair testing at any of our nationwide centers. Generally, 1.5 to 2 inches of hair from the scalp or body can be used. Our hair tests can determine the presence of drugs, alcohol/ETG, or can be tailored to specific testing needs.
In recent years, hair follicle drug tests have become a more prevalent method for detecting drug use. Many employers, courts, and substance abuse professionals opt for hair drug tests over standard urine tests. Employers imposing zero-tolerance policies, courts, and probation cases frequently require these tests. The primary advantage of hair follicle testing is its ability to detect drug use over a prolonged period—up to 90 days—collected in an observed and secure manner, rendering it nearly impossible to circumvent. For recent drug use detection within the past 5 days, urine tests remain the most precise option.

Hair testing has become known as an effective method for discovering drug and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by embedding biomarkers within the strands of hair as they grow. When gathered from close to the scalp, hair can offer a detection period for alcohol and other drugs of up to roughly three months. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of approximately 200 hairs (comparable to a #2 pencil's size) nearest the scalp provides 100mg, which is the optimal sample for screening and verification. For EtG, add-ons, or more extensive tests beyond 10 panels, an amount of 150mg is suggested. Using a jeweler’s scale to weigh the sample is advisable. If there is no available scalp hair, a similar quantity of body hair can be used. When discussing head hair, we mean scalp hair specifically. Body hair includes all other kinds (facial, underarm, etc.).
Process Overview
The key phases in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample within a lab’s framework. This comprises checking if the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and fulfilling additional data entry that isn't provided by an electronic chain of custody mechanism.
Screening involves a preliminary swift assessment for drugs of abuse. Although Screening is an economical approach to exclude drug usage for most samples, a positive screening must be confirmed for legal admissibility. Samples showing presumptive positives in Screening need further confirmation.
If a sample appears presumptive positive in Screening, additional hair is extracted from the initial sample for preparation in Extraction. Here, drugs are extracted from hair at significantly lower levels than with other methods (such as urine or saliva), representing why hair drug screening is notably challenging to execute.
Confirmation for any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive are cleansed before confirmation if needed. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

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.
