Accredited Drug Testing offers comprehensive hair follicle drug testing in Dieringer, Washington. For those needing a hair drug or alcohol test, we are experts in this area and provide testing at centers across the nation, including all cities. Generally, you need 1.5 to 2 inches of hair from the crown of your head, but body hair might suffice. Hair tests can be customized for drugs, alcohol/ETG, and other specific requirements.
In recent times, drug testing often involves the hair follicle method. Hair drug tests are increasingly preferred by employers, legal authorities, and substance abuse experts over the conventional urine tests. Employers with strict drug policies, courts, and probationary officers favor this approach. The key advantage is its extended detection window, often up to 90 days, ensured by observed sample collection, making it nearly foolproof. Nonetheless, for identifying drug use within the past 5 days, urine tests remain the gold standard.

The utilization of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair serves as a repository for long-term usage history by embedding biomarkers within its fibers as the strand grows. When gathered from near the scalp, hair can reveal alcohol and drug consumption within an approximate three-month period. The process of collecting hair is straightforward, relatively tamper-proof, and straightforward to transport.
A 1.5-inch segment containing about 200 hair strands (similar in size to a #2 pencil) located closest to the scalp will yield 100mg of hair, which is the optimal amount for both screening and confirmation. For extended tests such as EtG or those exceeding 10 panels, a 150mg sample is advisable. It's suggested to measure the sample using a jeweler's scale. If scalp hair is not an option, a comparable volume of body hair can be used. Head hair refers exclusively to scalp hair, while body hair encompasses all other types (including facial and axillary).
Process Overview
The drug test analysis in the laboratory involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is entered into a laboratory's system. This stage involves ensuring the sample was correctly sealed and delivered, generating a random LAN (Laboratory Accessioning Number), and completing any additional input that isn't captured by an electronic chain of custody.
Screening includes an initial abbreviated evaluation to identify drugs of abuse. This step is an economical approach to dismiss drug usage in most samples, although a positive result must undergo confirmation to be legally admissible. Samples with a presumptive positive result in Screening require further confirmation.
If a sample is presumed positive during the Screening step, additional hair is extracted from the initial sample to prepare for Extraction. Here, drugs are retrieved from hair at much lower concentrations when compared to other techniques (such as urine or oral fluid), which contributes to the complexity of hair drug screening.
Any positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed as necessary. The entire laboratory testing protocol, from Accessioning to Confirmation, is conducted under the supervision of the CAP (College of American Pathologists) Hair category and accredited to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", the test analyzes the hair strand rather than the 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.
