At Accredited Drug Testing located in Gualala, California, we offer comprehensive hair follicle drug evaluations. If a hair or alcohol test is what you require, we're experts in hair assessments and facilitate them at centers throughout the nation. Typically, 1.5 to 2 inches of hair from the crown or body suffices. Hair testing can identify drugs, alcohol/ETG, among other options tailored for hair analysis.
Recently, hair follicle drug tests have gained traction as a preferred method for drug evaluation. These tests are often mandated by employers, judicial bodies, and Substance Abuse Specialists in lieu of traditional urine tests. Hair follicle assessments are favored where zero-tolerance drug policies are in place, by courts, and for those on probation, due to their extended 90-day detection period and the challenge in tampering with the samples. However, when it comes to identifying drug use within a 5-day window, the urine test remains the most precise.

The utilization of hair testing is increasingly recognized as an effective method for uncovering drug and alcohol consumption. Hair offers a comprehensive historical account of alcohol and other drugs by embedding biomarkers within the developing hair strand's fibers. A proximity-based sample taken near the scalp can deliver an approximate 3-month timeframe for the detection of alcohol and other drugs. The collection process for hair is straightforward, relatively resistant to tampering, and convenient for transportation.
Obtaining a 1.5-inch segment from around 200 hair strands, approximately matching a #2 pencil's thickness, near the scalp can yield a 100mg sample, ideal for both initial tests and subsequent confirmations. For tests such as EtG, add-ons, or above 10 panels, a 150mg sample is advisable. We suggest weighing this sample on a jeweler's scale. If scalp hair isn't available, an equivalent quantity of body hair can be gathered. "Head hair" strictly refers to scalp hair, while "Body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four essential phases in processing a drug test result in a laboratory setting include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is first processed into the laboratory's system. This step confirms that the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any other necessary data input absent from an electronic chain of custody system.
Screening entails an initial quick assessment for drugs of abuse. Screening provides a cost-efficient method to eliminate drug usage for most samples, but any positive screen must be verified to stand in court. Samples flagged as presumptively positive in Screening undergo a secondary confirmation.
Presumptively positive samples from the Screening phase necessitate additional hair extraction from the initial specimen to prepare for Extraction. During Extraction, drugs are isolated from hair at far lower concentrations than alternative methods (e.g., urine or oral fluid), explaining the complexities of hair drug screening.
Confirmation of positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed prior to Confirmation if needed. The overall laboratory procedure, from Accessioning through Confirmation, undergoes review under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", the testing itself analyzes the hair strand rather than the hair follicle beneath the scalp.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
