Accredited Drug Testing provides comprehensive hair follicle drug analyses in North El Monte, California. If a hair drug or alcohol test is necessary, Accredited Drug Testing excels in this area, boasting centers across all cities nationally for convenient testing. Generally, 1.5 to 2 inches of hair are required from the head's crown or other body parts may be used. Hair testing can identify drugs, alcohol/ETG, and other custom options.
Hair follicle drug testing has become a popular method in recent years. Employers, legal systems, and substance abuse experts opt for hair tests over typical urine testing. Hair follicle exams appeal to zero-tolerance employers, courts, and those on probation because they offer a detection window of up to 90 days, are gathered under observation, and are notoriously hard to manipulate. However, urine tests remain superior for identifying drug use within five recent days.

Hair testing is increasingly recognized as a valuable method for identifying drug and alcohol consumption. The long history of substance use is captured by biomarkers embedded in the growing hair strands. When cut near the scalp, hair can reveal up to about a three-month period of drug and alcohol history. The collection process is straightforward, it's relatively hard to tamper with, and it is easy to transport.
A sample from the scalp of around 1.5 inches and approximately 200 hair strands (roughly the width of a #2 pencil) will yield 100mg, which is ideal for screening and validation. For EtG, additional analyses, or tests over 10 panels, 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. If scalp hair is not an option, an equivalent body hair sample can be used. When we mention head hair, it is specific to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processes involved in a drug test result comprise four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial introduction of a sample into the laboratory's system. This step ensures the sample is properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data not available through an electronic chain of custody system.
Screening involves a preliminary assessment for substances of abuse. While Screening is an economical means to exclude drug use in most samples, a positive result here must be validated for legal acceptability. Any samples with a presumptive positive in Screening require further confirmation.
In cases of presumptive positive results during Screening, additional hair is extracted from the original specimen for further preparation in the Extraction process. At this phase, drugs are extracted from hair at much lower concentrations than in methods like urine or oral fluid testing, making hair drug testing the most challenging methodology.
The confirmation of any positive screening involves techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation complies with the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 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. 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.
