In Maryhill, Washington, comprehensive hair follicle drug testing is offered by Accredited Drug Testing. Whether you require a hair drug or alcohol test, our specialty lies in hair testing, with nationwide testing facilities available to conduct such tests. Generally, hair from your head or body, measuring 1.5 to 2 inches, suffices for the test, which can screen for drugs, alcohol/ETG, or other tailored testing methods.
Hair follicle drug tests have become increasingly common in drug testing over the years. Various organizations such as employers, legal entities, and substance abuse experts choose hair drug tests over urine tests. This preference is due to the extended drug detection period of up to 90 days, providing a more effective inquiry for employers with strict policies, and during testing, it is challenging to manipulate the result. Conversely, urine tests remain the go-to for recent drug use detection within the past five days.

Hair analysis is increasingly recognized as a robust method for detecting drug and alcohol consumption. By embedding biomarkers in the strands of hair as they grow, it offers a prolonged overview of drug and alcohol use. Sampling close to the scalp yields up to a 3-month detection span for alcohol and drugs. Collecting hair is straightforward, resistant to tampering, and convenient for shipping.
A 1.5-inch sample comprising roughly 200 hairs (approximate thickness of a #2 pencil) near the scalp equates to 100mg, which is the preferred amount for testing and verification. For EtG and tests over 10 panels, 150mg is advisable. It's best to measure the sample using a jeweler’s scale. If head hair is not present, a similar mass of body hair can be used. Head hair specifically refers to scalp hair, while body hair encompasses other types (facial, underarm, etc.).
Process Overview
The laboratory testing process for drugs encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase where a sample is logged into the laboratory system. This step entails confirming the proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any outstanding data entry that the electronic chain of custody doesn't cover.
Screening is a preliminary evaluation to ascertain the presence of drugs. Although cost-efficient for eliminating drug use in many samples, any positive screen must be verified before being legally valid. Presumptively positive samples during Screening need secondary authentication.
If a sample appears positive in Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair at significantly lower levels than other methods (such as urine or saliva), making hair drug screening particularly challenging.
Positive screening outcomes are confirmed through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleaned before confirmation if necessary. From the initial Accessioning to final Confirmation, the entire lab procedure is overseen in compliance with both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly called "hair follicle tests", the test examines 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.
