Accredited Drug Testing offers comprehensive hair follicle testing services in Valle Vista, Texas. Our expertise extends to both hair drug and alcohol tests, with our centers available in cities nationwide. For accurate testing, individuals should have 1.5 to 2 inches of head or body hair. Hair testing analyzes for a range of substances including drugs and alcohol/ETG and offers custom testing solutions.
Hair follicle drug tests have become more common in drug testing procedures in recent years. Increasingly, employers, courts, and substance abuse experts mandate these tests over traditional urine tests due to their accuracy and reliability. These tests are favored for their extensive detection period of up to 90 days, secure collection process, and resistance to tampering, making them essential for maintaining zero-tolerance policies. However, for recent drug use detection, within a 5-day window, urine tests remain effective.

Hair testing is recognized as a potent method for identifying drug and alcohol involvement. Hair retains a prolonged history of alcohol and other substances by encasing biomarkers within the fibers of the expanding hair strand. When obtained near the scalp, hair can offer up to nearly a 3-month detection span for alcohol and other substances. Hair is straightforward to gather, a bit challenging to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp will provide 100mg of hair, the optimal sample size for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg sample is advisable. It's suggested to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be obtained. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The four primary phases in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample into a lab’s system. This stage confirms the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finishes any additional data entry not available from an electronic chain of custody system.
Screening constitutes a preliminary rapid inspection for drugs of abuse. Although Screening is an economical method to rule out drug consumption for most samples, a positive screening result needs to be confirmed for court admissibility. Any samples deemed presumptively positive in Screening necessitate a secondary verification.
In cases where a sample is presumptively positive during the Screening stage, additional hair is taken from the initial sample and made ready for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug screening the most intricate method to execute.
Confirmation for any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation as required. The entire lab process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Note: Although frequently termed "hair follicle tests", the test itself examines 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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
