Accredited Drug Testing provides comprehensive hair follicle drug assessments in Haiwee, California. For those requiring hair-based drug or alcohol analysis, Accredited Drug Testing's expertise in hair evaluation is unmatched, with facilities nationwide capable of conducting such tests. Typically, 1.5 to 2 inches of hair from the crown or body are needed. Hair tests can evaluate drugs, alcohol/ETG, and other specialized testing services.
In recent times, drug testing approaches have increasingly embraced hair follicle evaluations. Workplaces, judicial systems, and substance abuse experts often prefer hair tests over traditional urine analyses. Hair follicle tests offer several advantages, including an extended detection timeline—generally up to 90 days—and are observed during collection, making it nearly impossible to falsify results. However, urine tests remain the most precise choice for detecting recent drug use within five days.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair analysis has emerged as a formidable method for identifying alcohol and drug consumption. Hair captures a prolonged history of substance use by incorporating biomarkers into the strands of growing hair. When gathered near the scalp, hair may reveal up to about a 3-month window for detecting alcohol and drugs. Hair is easy to gather, somewhat challenging to alter, and is straightforward to transport.
A 1.5-inch specimen consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest the scalp will yield 100mg of hair, the preferred sample size for both screening and verification. For EtG, additional tests, or those beyond 10 panels, a specimen weighing 150mg is advised. We suggest measuring the sample weight with a jeweler’s scale. If there's no scalp hair available, an equivalent quantity of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory procedures for processing a drug test encompass four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is integrated into the lab’s system. This process involves ensuring that the sample was correctly sealed and delivered, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any outstanding data not covered by an electronic chain of custody procedure.
Screening is a preliminary check for substances of abuse. Although Screening offers an economical way to exclude drug use in most cases, any positive results must be confirmed for legal acceptability. Samples with a presumptive positive result during Screening require further confirmation.
If a sample shows presumptive positivity in Screening, additional hair is collected from the source sample and readied for Extraction. In this phase, drugs are extracted from hair at markedly lower concentrations than found in other techniques (such as urine or saliva), underscoring why hair drug analysis is the most challenging method to execute.
Verification of any positive Screen result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if required. The entire lab process, from Accessioning to Confirmation, adheres to the rigorous standards of the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 certification.
Advantages of hair drug testing:
Limitations:
Note: Despite being termed "hair follicle tests", the analysis is conducted on the hair strand itself, not on the follicle beneath the scalp.

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.
