Accredited Drug Testing offers comprehensive hair follicle drug tests in Stevinson, California. For those seeking hair drug or alcohol screenings, Accredited Drug Testing is an expert in hair testing, with centers across the nation for hair testing. Hair measuring 1.5 to 2 inches from the scalp or body can be used. Hair tests can screen for drugs, alcohol/ETG, or include alternative custom options.
Recently, hair follicle drug testing has become a more common approach. Numerous employers, judges, and substance abuse counselors request hair testing over the traditional urine method. Employers with zero-tolerance policies, legal systems, and probationary obligations often rely on hair testing. Its main advantage is a longer drug detection window of up to 90 days, collected under supervision, making it nearly tamper-proof. Nonetheless, urine testing is more precise for screening recent drug use within the past 5 days.

Hair testing is now recognized as a robust method for identifying the use of drugs and alcohol. Hair can capture the long-term presence of alcohol and other substances by embedding biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair offers roughly a detection period of up to 3 months for alcohol and drugs. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.
A sample measuring 1.5 inches of around 200 hair strands (comparable in size to a #2 pencil) close to the scalp yields 100mg of hair, considered the optimal sample for both screening and confirmation. For EtG, additional tests, and/or tests over 10 panels, a specimen of 150mg is advised. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair isn't available, the same amount of body hair can be collected. When mentioning head hair, it specifically means scalp hair. In contrast, body hair includes all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the sample's initial incorporation into a laboratory system. This process confirms the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry missing from an electronic chain of custody system.
Screening involves a preliminary swift check for substances of abuse. While Screening is a cost-effective measure to exclude drug use in most samples, a positive screen necessitates confirmation for legal admissibility. Any samples that are presumptively positive during Screening require additional confirmation.
If the Screening phase indicates a presumptive positive, more hair is retrieved from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug screening is among the most challenging techniques to execute.
Confirmation for any positive result in Screening is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive are washed before confirmation as required. The complete laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

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.
