Accredited Drug Testing provides comprehensive hair follicle drug examinations in Barstow, California. If you're seeking a hair drug or alcohol assessment, we focus on hair evaluations, with testing sites across all cities Nationwide ready to execute the test. You should have approximately 1.5 to 2 inches of hair on the crown, or body hair may be viable in many instances. Hair samples can be scrutinized for narcotics, alcohol/ETG, or other tailored hair testing alternatives.
Recently, hair follicle drug testing has increasingly been the chosen method for drug screening. Many employers, judicial bodies, and Substance Abuse councils now mandate a hair drug evaluation instead of the traditional urine analysis. Hair follicle tests are selected by employers enforcing strict no-drug-use protocols, courts, and individuals under probationary supervision. The standout advantage of hair testing is its extended window of drug detection, which can reach up to 90 days, collected under observed conditions, and is challenging to manipulate. Nonetheless, when screening for drug consumption within the past five days, urine tests remain the most precise.

Hair screening has gained recognition as a potent method for identifying drug and alcohol consumption. Hair strands encapsulate biomarkers within their fibers, offering a long-term record of substance use. When gathered near the scalp, hair can reveal substance use history extending up to 3 months. It is simple to collect, less prone to tampering, and easy to transport.
A 1.5-inch cut of around 200 hair strands (about the thickness of a #2 pencil) near the scalp gives 100mg of hair, optimal for both preliminary and confirmatory testing. For EtG, additional screenings, or extensive tests beyond 10 panels, a 150mg sample is advisable. Using a jeweler’s scale is suggested to weigh the sample. If scalp hair is not available, a comparable quantity of body hair can be used. By "head hair", only scalp hair is implied. "Body hair" indicates other hair types (facial, axillary, etc.).
Process Overview
The core steps in the lab processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a specimen into a lab's framework. This entails ensuring the sample was sealed and shipped properly, assigning a unique LAN (Laboratory Accessioning Number), and completing any other data input not managed by an electronic chain of custody protocol.
Screening constitutes a preliminary quick assessment for substances of abuse. Though Screening is economically effective for eliminating drug use in most samples, any positive screen must be confirmed for legal acceptability. Any samples presumptively positive in Screening necessitate further confirmation.
If Screening yields a presumptive positive result, additional hair from the initial specimen is used for Extraction. This phase involves extracting substances from hair at much lower concentrations than other methods (e.g., urine or oral fluid), emphasizing why hair drug screening is the most complex method to execute.
The confirmation of any positive screen occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the compliance with ISO/IEC 17025 criteria.

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.
