Accredited Drug Testing offers comprehensive hair follicle drug testing services in Fairfax, CA. For those who require hair or alcohol testing, we provide expert hair analysis through our nationwide network of centers. Typically, 1.5 to 2 inches of hair from the crown or body is required. Our analysis covers drugs, alcohol/ETG, or additional tailored testing options.
In recent times, hair follicle testing has become a predominant method for drug screening. Employers, legal courts, and substance abuse advisors are increasingly opting for hair tests over traditional urine tests. Employers with zero-tolerance policies, courts, and probation officers prefer this method due to its extended detection window of up to 90 days and observed collection process, which minimizes chances of tampering. However, for drug use detection within the past 5 days, urine tests remain the most accurate choice.

Hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair offers a prolonged timeline of substance use by embedding biomarkers within the hair's fibers as it grows. When the sample is taken near the scalp, hair can reveal up to a roughly 3-month period for detecting drugs and alcohol. Hair collection is straightforward, tampering with it is somewhat challenging, and it is uncomplicated to transport.
A sample measuring 1.5 inches containing approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for both screening and confirming results. For EtG, additional tests, and/or tests exceeding 10 panels, a specimen size of 150mg is advised. Using a jeweler’s scale to weigh the specimen is suggested. In the absence of scalp hair, a similar quantity of body hair may be gathered. When discussing head hair, we specifically mean scalp hair. Body hair pertains to all other types of hair (facial, axillary, etc.).
Process Overview
The drug testing process in a laboratory encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the laboratory's system. This step involves ensuring the sample has been appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening constitutes a preliminary rapid evaluation for substances of abuse. Despite being an economical approach to dismiss drug usage in most samples, a positive screening result necessitates confirmation to be valid in legal settings. Samples that exhibit a presumptive positive in Screening necessitate a further validation process.
If Screening indicates a presumptive positive, additional hair is extracted from the primary specimen for the Extraction phase. During Extraction, drugs are isolated from the hair at a significantly lower concentration compared to other testing methods (like urine or oral fluid), underscoring the complexity of conducting hair drug screening.
Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing prior to confirmation as needed. The entire laboratory sequence from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", this analysis actually focuses on the hair strand and not the follicle beneath the scalp.

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.
