Accredited Drug Testing provides extensive hair follicle testing services in Vernon, Arizona. For those in need of drug or alcohol hair tests, Accredited Drug Testing excels in this field, with centers located nationwide for convenience. Generally, a minimum of 1.5 to 2 inches of hair from the crown or body is required. Hair tests can detect a range of substances, including drugs and alcohol/ETG, with options for tailored testing.
Recently, drug testing methods increasingly favor the use of hair follicle tests. Employers, judicial systems, and addiction professionals often prefer hair tests over urinalysis. Hair follicle tests are chosen by employers with strict drug policies, legal entities, and those supervising probation. The main advantage of a hair drug test is its longer detection period—up to 90 days—making it difficult to alter, compared to urinalysis, which is more effective for recent use detection within 5 days.

Hair examinations are increasingly recognized as an effective resource for detecting drug and alcohol consumption. Hair offers an extensive timeline of alcohol and drug intake by embedding biomarkers within its growing fibers. When obtained near the scalp, hair can reveal substances used over a span of about three months. Hair collection is straightforward, somewhat resistant to tampering, and convenient for transportation.
A 1.5-inch segment of approximately 200 hair strands (equivalent to the size of a #2 pencil) closest to the scalp yields about 100mg, which is the optimal quantity for evaluation and validation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. Using a jeweler's scale to measure the specimen is recommended. Should scalp hair be unavailable, a similar volume of body hair can be gathered. References to head hair imply exclusively scalp hair, whereas body hair pertains to all other types (such as facial and axillary).
Process Overview
The four principal stages in laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample into a lab's system. This phase involves confirming that the sample was sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody system.
Screening consists of an initial rapid assessment for substances of abuse. Although Screening is a cost-efficient method to exclude drug use in most samples, a positive screen must be validated to be legally accepted. Samples that test presumptively positive during Screening necessitate further confirmation.
Upon a presumptive positive in the Screening phase, additional hair is taken from the original sample and prepared for Extraction. Here, drugs are extracted from hair at considerably lower concentrations compared to other methods (such as urine or oral fluid), highlighting why hair drug screening is one of the most challenging methodologies.
Verification of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as needed. The entire laboratory workflow from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed as "hair follicle tests", these tests actually analyze the hair strand rather than the hair 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.
