Accredited Drug Testing offers comprehensive hair follicle drug tests in Sierraville, California. Whether you require a hair drug or alcohol test, we are experts in hair testing and have facilities nationwide. Testing guidelines suggest that hair from the crown or body (between 1.5 to 2 inches long) is typically utilized. Our tests can screen for drugs, alcohol/ETG, and other personalized options.
Recently, the preference for conducting drug tests has shifted towards hair follicle testing. Employers, the legal system, and Substance Abuse experts are opting for hair analysis over standard urine tests. Hair follicle testing is preferred by employers with strict no-drug policies, the courts, and probation services. The main advantage of hair testing is its extended detection timeframe of up to 90 days, requiring observation during sample collection, making it almost infallible. However, for drug usage detection within the first 5 days, urine tests remain the definitive choice.

Hair analysis has emerged as a robust method for identifying alcohol and drug usage. The hair strand captures a prolonged record of substance exposure by encasing biomarkers within its growing fibers. When gathered near the scalp, it can detect substances over a span of nearly three months. The collection process is straightforward, resistant to tampering, and convenient for transport.
A sample of 1.5 inches or approximately 200 strands (similar to the thickness of a #2 pencil) nearest the scalp yields the optimal 100mg necessary for both screening and verification. For EtG, additional analyses, and tests exceeding 10 panels, 150mg is advised. Using a jeweler’s scale to weigh the sample is recommended. In the absence of scalp hair, an equivalent portion of body hair can be obtained. References to head hair specifically denote scalp hair, while body hair encompasses all other growth types (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory drug testing process include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, samples undergo initial integration into the laboratory’s database. This step verifies the secure sealing and proper shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing details not covered by an electronic chain of custody system.
Screening constitutes a preliminary assessment for the presence of illicit substances. While it offers a budget-friendly approach to exclude drug presence in most samples, a positive outcome necessitates confirmation for courtroom validity. Samples that tentatively test positive during Screening require further confirmation.
Should a sample test tentatively positive in the Screening, additional hair is sourced from the original batch for the Extraction phase. Here, drug compounds are isolated from hair at an exceptionally diluted rate compared to other methods (e.g., urine or oral fluid), underscoring the complexity of performing hair drug screens.
Confirmation of positive findings is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples undergo a cleaning process as part of the confirmation phase. The entire sequence from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair criteria and accreditation under 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.
