Accredited Drug Testing provides comprehensive hair follicle drug tests in University Place, Washington. For hair or alcohol testing needs, we specialize in hair testing with centers nationwide. Typically, 1.5 to 2 inches of cranial or body hair is needed. Hair tests can be customized to detect drugs, alcohol, or other specific substances.
Recently, hair follicle drug testing has become more common. It's favored by employers, courts, and substance abuse experts over traditional urine tests. These tests are crucial for employers with strict drug policies and help courts and probation officers. Hair tests can detect drug use for up to 90 days and are performed under observation, making them hard to manipulate. For recent drug use within 5 days, urine tests are still the most reliable.

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. By trapping biomarkers within the fibers of hair strands, it provides a long-term history of alcohol and other drugs. When cut close to the scalp, hair samples can reveal a detection window of up to around 3 months for alcohol and various drugs. Hair collection is straightforward, tough to tamper with, and convenient to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (about #2 pencil thickness) near the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG tests or panels exceeding 10, 150mg of the sample is advisable. It's suggested to weigh the sample using a jeweler's scale. Should scalp hair be unavailable, collecting an equivalent amount of body hair is permissible. "Head hair" refers exclusively to scalp hair, while "body hair" denotes all other body hair types (such as facial and axillary hair).
Process Summary
The laboratory processing of a drug test result encompasses four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial registration of the sample into the lab system. This involves confirming the sample's proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and completing additional data entries not covered by an electronic chain of custody system.
Screening constitutes a preliminary rapid assay for drug abuse. Although economically efficient for excluding drug usage in most samples, a positive screen must undergo confirmation to be considered court-admissible. Presumptively positive samples during Screening necessitate secondary confirmation.
Should a sample yield a presumptive positive during the Screening phase, additional hair is extracted from the original sample and readied for the Extraction step. At this juncture, drugs are isolated from hair at markedly lower concentrations compared to other testing methods (such as urine or oral fluid), accounting for the complexity of hair drug screening methodologies.
Positive screening outcomes are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptively positive samples are cleansed as required. From Accessioning through Confirmation, the entire laboratory process is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Drawbacks:
Note: Despite being termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
