Accredited Drug Testing offers comprehensive hair follicle drug assessments in Homestead Valley, CA. If a hair drug or alcohol test is required, our specialty in hair testing is supported by nationwide centers ready to conduct these tests. Typically, hair length should be 1.5 to 2 inches from the crown or body. Tests can detect drugs, alcohol/ETG, and provide custom options.
Recently, hair follicle testing has become a preferred method for drug testing. Employers, courts, and substance abuse experts increasingly select hair drug tests over urine tests. These tests are ideal for employers with zero-tolerance policies, as well as for courts and those on probation. The main advantage is a broader detection window of up to 90 days, with an observed collection process, making cheating difficult. However, for recent drug use, under five days, a urine test remains most accurate.

Hair analysis has gained recognition as an effective method for detecting substance and alcohol use. Hair captures a long-term record of alcohol and other drugs by incorporating biomarkers within the growing hair strand's fibers. When gathered near the scalp, hair can offer up to roughly a 3-month detection timeframe for alcohol and other drugs. The collection of hair is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment comprising about 200 hair strands (around the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the perfect amount for screening and verification. For EtG, expanded panels, and/or screenings exceeding 10 panels, a 150mg sample is advisable. It is suggested to measure the sample using a jeweler’s scale. If scalp hair is unattainable, a comparable quantity of body hair can be used. When referencing head hair, we specifically mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The four key stages in the laboratory evaluation of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary processing of a sample into a lab’s system. This process ensures that the sample was properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not already provided by an electronic chain of custody system.
Screening involves a preliminary swift analysis for drugs of abuse. Although Screening is a cost-efficient strategy to exclude drug use in most samples, a positive screen must be confirmed to be admissible in legal settings. Any samples identified as possibly positive in Screening do require additional confirmation.
If a sample shows potential positivity in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are isolated from hair at much lower concentrations than in alternative methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Any positive screening outcome is verified via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with potential positivity are cleansed before confirmation if needed. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 benchmarks.

Limitations:
Note: Despite being commonly called "hair follicle tests", the test examines the hair strand and not the follicle beneath the scalp

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
