In Lake Cavanaugh, Washington, Accredited Drug Testing offers comprehensive hair follicle drug testing services. With specialized expertise in hair testing, we operate nationwide facilities capable of conducting hair-based drug and alcohol assessments. Typically, 1.5 to 2 inches of hair is needed from the head or body. These tests can detect substances, alcohol/ETG, or be modified for specific needs.
Increasingly, hair follicle drug tests are the preferred method for drug screening. Many employers, judges, and addiction experts are turning to this method over traditional urine tests. Hair tests are favored by those enforcing zero-tolerance drug policies, including employers and courts. Their main advantage is a longer detection period, up to 90 days, minimized cheating risks through direct observation, although for detecting very recent drug use within 5 days, urine tests remain more precise.

The perception of hair testing has evolved into a robust method for identifying alcohol and drug use. Hair maintains an extended record of substance intake by capturing biomarkers within the hair's growing fibers. When taken near the scalp, hair can reveal up to a three-month history of alcohol and drug usage. Hair is straightforward to gather, relatively hard to tamper with, and convenient to send.
A section of hair measuring 1.5 inches with around 200 strands (similar in size to a #2 pencil) near the scalp offers 100mg, the preferred amount for both screening and confirmation. For EtG, extra tests, and tests surpassing 10 panels, a 150mg sample is advised. We suggest assessing the sample's weight with a jeweler's scale. If scalp hair isn't accessible, an equivalent quantity of body hair can be used. The term "head hair" specifically denotes scalp hair. In contrast, "body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary entry of a sample into a lab's system. This process verifies proper sealing and shipping of the sample, assigns a randomized LAN (Laboratory Accessioning Number), and completes any missing data entry not covered by an electronic chain of custody.
Screening consists of an initial swift check for substance abuse. While Screening offers an economical method to eliminate drug usage for most samples, a positive finding needs confirmation to hold up in legal proceedings. Samples displaying positive results in Screening necessitate additional confirmation.
Should a sample indicate a positive result during Screening, additional hair is extracted from the primary specimen to prepare for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), making hair drug analysis one of the most intricate methodologies.
Confirmation of positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Samples with preliminary positive results undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

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.
