In Purdy, Washington, Accredited Drug Testing offers comprehensive hair follicle drug testing. If a hair or alcohol test is required, our centers are available in every city across the nation, providing specialized hair testing services. Generally, a length of 1.5 to 2 inches of hair from the crown or other body areas is necessary. Hair analysis can detect drugs, alcohol/ETG, or other tailored testing options.
Recently, the popularity of hair follicle drug tests has risen. Employers, judicial systems, and Substance Abuse experts often favor hair tests over traditional urine tests. For zero-tolerance environments, court mandates, or probation compliance, hair tests are invaluable. Their key advantage lies in detecting drug use over a longer timeframe, typically up to 90 days, through an observed collection process that’s challenging to evade. Nonetheless, for recent drug activity, a urine test remains the most accurate.

Hair testing has become recognized as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of alcohol and drug use by capturing biomarkers within the hair strand's fibers. When sourced close to the scalp, hair can reveal up to a 3-month detection period for alcohol and drugs. Collecting hair is straightforward, relatively tamper-resistant, and simple to transport.
A 1.5-inch piece comprising approximately 200 hair strands (similar in thickness to a #2 pencil) nearest to the scalp provides 100mg of hair, which is optimal for screening and verification. For EtG, supplemental tests, or panels exceeding 10, 150mg of the sample is suggested. It's advisable to measure the sample with a jeweler’s scale. If scalp hair isn't accessible, a comparable quantity of body hair can be gathered. Mention of head hair specifies scalp hair exclusively, while body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The primary stages in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's initial integration into the laboratory framework. This encompasses ensuring the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and performing any remaining data entry not covered by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for drug abuse. Although Screening is a cost-efficient means to negate drug usage in most samples, a positive screen needs validation to be court-admissible. Samples that appear positive in Screening necessitate a further confirmation.
If a sample seems positive during the Screening phase, more hair is extracted from the initial specimen for the Extraction stage. In this stage, drugs are retrieved from hair in much lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug testing the most complex methodology to execute.
Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS or LC/MS/MS. All samples presumed positive are cleansed before confirmation when needed. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Though frequently termed as "hair follicle tests", the analysis targets the hair strand itself 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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
