Accredited Drug Testing offers comprehensive hair follicle drug assessments in Selma, California. If you're in need of a hair drug or alcohol analysis, they are experts in hair testing with facilities across all cities in the nation capable of performing such tests. It requires having 1.5 to 2 inches of hair from your head or body, which is generally used. Hair evaluations can be conducted for substances, alcohol/ETG, or other customized testing options.
In recent years, hair follicle drug tests have become a more common method for conducting drug screenings. A growing number of employers, courts, and Substance Abuse specialists now prefer hair drug tests over the traditional urine tests. Hair follicle drug tests are mandated by employers with zero-tolerance policies on drug use, judicial systems, and individuals under probation. The key advantage of hair follicle tests is their significantly longer detection window for drug use, extending up to 90 days, obtained in an observed manner, making deception nearly impossible. Yet, for screening drug intake within the past 5 days, urine tests remain unmatched in accuracy.

Hair analysis is now recognized as a potent method for identifying drug and alcohol consumption. Hair strands encapsulate a long-term record of alcohol and drugs by capturing biomarkers within the fibers of the expanding hair. When gathered close to the scalp, hair can reveal usage patterns for up to around a 3-month period for alcohol and drugs. Hair is easy to gather, challenging to tamper with, and straightforward to send.
A 1.5-inch section comprising roughly 200 hair strands (similar to the width of a #2 pencil) nearest to the scalp delivers 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, add-ons, and/or assays exceeding 10 panels, 150mg of the sample is suggested. We endorse using a jeweler’s scale for weighing the sample. If scalp hair is not accessible, a corresponding amount of body hair might be utilized. When discussing head hair, we mean only scalp hair. Body hair includes all other types (beard, armpits, etc.).
Process Overview
The principal steps in the lab analysis of a drug testing sample include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample in a laboratory's system. It involves checking that the sample was securely sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody procedure.
Screening addresses a preliminary rapid assessment for substances of abuse. Though Screening is an economical method to rule out drug usage in the majority of samples, a positive screening requires confirmation to be valid in legal settings. Samples that yield a presumptive positive on Screening need a secondary confirmation.
In cases where a sample tests presumptively positive during the Screening phase, additional hair is retrieved from the original sample and readied for Extraction. During Extraction, drugs are withdrawn from hair at much lower concentrations than through other methods (e.g., urine or saliva), making hair drug screening the most complex methodology to conduct.
Confirmation of any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed pre-confirmation as required. Each phase of the lab process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair specifications and accredited to ISO/IEC 17025 standards.

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.
