Accredited Drug Testing provides comprehensive hair follicle drug testing services in Harper, Washington. For those in need of hair-based drug or alcohol screening, we specialize in this method with testing facilities available in every city across the nation. Generally, a hair length of 1.5 to 2 inches from the crown or other body hair can be used. These tests can detect drugs, alcohol/ETG, or be tailored for other specific requirements.
Hair follicle drug tests have become a more prevalent method for drug screening in recent years. A multitude of employers, judicial systems, and substance abuse experts now opt for hair testing over traditional urine tests. This method is particularly favored by zero-tolerance employers, legal entities, and those overseeing probation. The key advantage of hair testing is its extended detection period of up to 90 days, making it harder to spoof due to its observed collection process. Nonetheless, urine tests remain most precise for detecting drug use within the past five days.

Hair analysis has emerged as an effective method for detecting the consumption of drugs and alcohol. Hair retains a long-term record of substance use by capturing biomarkers within the structure of the hair strand as it grows. Collected near the scalp, hair can offer a detection period of up to about three months for alcohol and drugs. Collecting hair is straightforward, comparatively tamper-resistant, and convenient for shipping.
A hair sample of 1.5 inches, consisting of around 200 strands (comparable to the thickness of a #2 pencil) near the scalp, provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, or evaluations exceeding 10 panels, a quantity of 150mg is suggested. It is advisable to measure the sample using a jeweler's scale. In cases where scalp hair is inaccessible, an equivalent volume of body hair is acceptable. When discussing head hair, it specifically means scalp hair only, while body hair encompasses all other types, such as facial or axillary hair.
Process Overview
The essential steps in processing a drug test in a laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial input of a sample into the laboratory's system. This step involves ensuring the sample is correctly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and finalizing any necessary information entry not completed by an electronic chain of custody system.
Screening consists of an initial rapid evaluation for substances of abuse. While Screening offers a cost-efficient method to check for substance use in most samples, a positive result needs further confirmation to hold up in judicial settings. Any sample that yields a presumptively positive Screening outcome mandates secondary confirmation.
If a sample returns a presumptively positive result during Screening, additional hair is extracted from the original sample and readied for Extraction. During Extraction, substances are removed from the hair at concentrations significantly lower than other methods (such as urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation of a positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are cleansed before confirmation as necessary. The entire laboratory process, from Accessioning to Confirmation, is evaluated under both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although sometimes called "hair follicle tests," the analysis is conducted on the hair strand and not the follicle beneath the scalp.

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.
