Accredited Drug Testing offers comprehensive hair follicle drug assessments in Marengo, Washington. If you're in need of a hair-based drug or alcohol test, Accredited Drug Testing is a specialist in this field with a network of testing facilities across all cities Nationwide, ready to conduct a hair drug screening. Typically, 1.5 to 2 inches of hair from the scalp or body is sufficient for most cases. These tests can evaluate for drugs, alcohol/ETG, or other personalized hair testing options.
In recent times, the adoption of hair follicle drug testing has grown. Many employers, judicial systems, and Substance Abuse authorities now favour hair drug tests over the conventional urine tests. Employers enforcing strict no-drug policies, legal courts, and individuals on probation increasingly use these tests. The main advantage of using hair follicle tests lies in their extended detection window for drug use—generally up to 90 days—which is overseen in a monitored collection process, making it nearly foolproof. However, urine testing remains the gold standard for detecting drug use within the immediate past 5 days.

Hair testing is recognized as an effective means for assessing drug and alcohol usage. The hair retains a comprehensive history of substances by capturing biomarkers within the strands as they grow. When taken near the scalp, this method can detect the presence of drugs and alcohol for up to about 90 days. Collecting hair is straightforward, hard to tamper with, and convenient to transport.
A sample of 1.5 inches consisting of roughly 200 hair strands (comparable to a #2 pencil) close to the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, it is advised to have 150mg of the sample. The specimen should be weighed on a jeweler’s scale. If scalp hair is absent, a similar quantity of body hair can be used. When referring to head hair, it specifically denotes scalp hair. Body hair encompasses other types such as facial and axillary hair.
Process Overview
The four primary stages involved in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a laboratory’s system. This step includes confirming the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.
Screening is a preliminary rapid test for drugs of abuse. While Screening is a cost-efficient method to exclude drug consumption for most samples, a positive result requires confirmation to be court-admissible. Any samples flagged as presumptively positive during Screening necessitate a follow-up confirmation.
If a sample shows presumptive positivity during the Screening phase, additional hair is taken from the initial sample and prepped for Extraction. In Extraction, drugs are isolated from hair at a significantly lower concentration than with other methods (e.g., urine or oral fluid), which is why hair drug testing is among the most challenging methodologies to execute.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as required. The entire laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite often being termed as "hair follicle tests", the test actually evaluates the hair strand rather than the follicle beneath the scalp.

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.
