In Catheys Valley, CA, Accredited Drug Testing is the go-to for comprehensive hair follicle drug tests. Our centers across the nation, including all cities, offer specialized hair drug and alcohol testing. Typically, 1.5 to 2 inches of crown or body hair is required for analysis, tailored to detect drugs, alcohol/ETG, and more.
Lately, workplaces, courts, and substance abuse professionals increasingly prefer hair follicle tests over urine tests. Employers with zero-tolerance policies find them invaluable due to their longer 90-day detection period. Collected under supervision, these tests are nearly foolproof. Yet, for recent usage (within 5 days), urine tests remain unmatched in accuracy.

Hair analysis has become recognized as an effective method for identifying substance and alcohol consumption. Hair reflects a prolonged timeline of alcohol and drugs by embedding biomarkers within the fiber of the growing strand. When sourced near the scalp, hair reveals up to a 3-month frame of detection for alcohol and drugs. It is straightforward to collect hair, relatively resistant to tampering, and simple to transport.
A 1.5-inch section of roughly 200 strands (comparable to the girth of a #2 pencil) closest to the scalp yields 100mg of hair, the preferred sample volume for testing and validation. For EtG, enhancements, and/or analyses beyond 10 panels, a 150mg quantity is advisable. We advocate measuring the specimen with a jeweler’s scale. If scalp hair is inaccessible, a comparable quantity of body hair may be taken. References to head hair pertain only to scalp hair, whereas body hair encompasses all other types like facial and axillary.
Process Overview
There are four pivotal stages in lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the entry of a sample into a laboratory’s system initially. This process includes confirming the correct sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and concluding any additional data entry omitted by an electronic chain of custody system.
Screening represents an initial, brief inspection for drugs of misuse. Though economical, Screening is essential to eliminate drug use in most samples, but a positive screen necessitates confirmation to be valid in legal settings. Any samples with presumptive positives in Screening demand a subsequent confirmation.
When a sample indicates a presumptive positive in the Screening phase, additional hair from the original sample is obtained for Extraction. Here, drugs are isolated from hair at levels considerably lower than other methods (like urine or oral fluid), part of why hair analysis is the most challenging technique to execute.
Confirmation for any positive screen is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation if needed. The complete process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair endorsement and the ISO / IEC 17025 accreditation 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.
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.
