Providing comprehensive hair follicle drug testing services, Accredited Drug Testing is your go-to resource in Arlington, Washington. If a hair-based drug or alcohol test is necessary, you can rely on our specialization in hair testing, with centers located throughout cities nationwide. For testing, 1.5 to 2 inches of hair from your head or body is typically required. Hair tests offer analysis for drugs, alcohol/ETG, and customized options.
Hair follicle drug tests have increasingly become part of the drug testing landscape over recent years. This method is preferred by many employers, courts, and substance abuse professionals over standard urine tests. With zero-tolerance policies, employers, courts, and those on probation favor hair follicle testing due to its longer drug use detection window of up to 90 days. Additionally, the observed collection method makes it nearly impossible to tamper with, offering a more reliable test, although for recent drug use within 5 days, urine tests still lead in accuracy.

Hair testing has emerged as an influential technique for identifying drug and alcohol consumption. It offers a long-term analysis of alcohol and drug levels by capturing biomarkers within the hair strand's fibers as it grows. When taken from the scalp, hair can show drug and alcohol use for up to three months. It's easy to collect, challenging to tamper with, and convenient to send.
A 1.5-inch hair sample consisting of roughly 200 strands (the size of a #2 pencil) near the scalp weighs about 100mg, which is optimal for screening and confirmation. For EtG, additional tests, and those exceeding 10 panels, a sample of 150mg is suggested. It's advisable to weigh this on a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be used. Scalp hair refers only to hair from the head, while body hair encompasses other types (facial, axillary, etc.).
Process Overview
The key steps in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage that involves integrating a sample into a lab’s system, ensuring it was sealed and shipped correctly, assigning a LAN (Laboratory Accessioning Number), and doing any extra data entry that may not have been done through an electronic chain of custody.
Screening conducts an initial check for drug use. Though it’s a cost-effective method to rule out drug use, a positive screen must be confirmed for legal validity. Samples with presumptive positives in Screening require additional confirmation.
If a sample shows positive in Screening, more hair is taken from the initial sample for Extraction. Drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening particularly complex.
Confirmation of positive screened results is done via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples are washed before confirmation as necessary. The process from Accessioning to Confirmation is examined under both CAP (College of American Pathologists) Hair designation and 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
