In Selma, Oregon, Accredited Drug Testing provides comprehensive hair follicle drug tests. Whether for drug or alcohol testing, our company excels at hair testing, with facilities available nationwide. Typically, 1.5 to 2 inches of hair is required from the head, or body hair may be used. Hair samples allow analysis for various substances, including drugs and alcohol/ETG.
The trend of using hair follicle drug tests for screening has gained momentum in recent years. Many employers, courts, and substance abuse bodies are opting for hair tests over traditional urine tests. Employers with stringent zero-tolerance policies and those monitoring probationers rely on this method. Its major advantage is the extended detection period of up to 90 days, with observations minimizing the risk of cheating. However, urine tests remain the most reliable for detecting recent drug use within five days.

Hair analysis is now regarded as an effective means for identifying substance and alcohol consumption. Hair maintains a prolonged record of alcohol and drugs by embedding biomarkers within the fibers of the hair as it grows. When sourced near the scalp, hair offers a detection period of up to around 3 months for alcohol and drugs. Hair is straightforward to gather, somewhat resistant to tampering, and simple to transport.
To ensure an optimal sample for analysis, a 1.5-inch segment comprising roughly 200 hairs (approximating the thickness of a #2 pencil) nearest to the scalp will yield 100mg. This is the preferred amount for testing and validation. For EtG, supplementary tests, and/or beyond 10-panel assessments, 150mg of the sample is advised. It's recommended to measure the collection on a jeweler’s scale. In cases of unavailability of scalp hair, a comparable portion of body hair may be used. When head hair is mentioned, it specifically refers to scalp hair. Body hair encompasses any other types (facial, axillary, etc.).
Process Overview
The four critical phases in processing a drug test result in a lab setting include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial handling of a sample into the lab's system. This step verifies that the sample was correctly sealed and sent, assigns a random Laboratory Accessioning Number (LAN), and finalizes any supplementary data input absent from an electronic custody chain.
Screening offers a preliminary fast assessment for illicit substances. Although Screening is a cost-efficient method to eliminate drug usage in the bulk of samples, a positive outcome requires confirmation to be legally acceptable. Any samples marked presumptive positive in Screening necessitate subsequent verification.
If a sample appears presumptive positive in Screening, additional hair is extracted from the initial collection for the Extraction phase. At this point, drugs are isolated from hair at notably lower concentrations than in other methods like urine or oral fluids, bolstering the complexity of hair drug testing.
The verification of any positive Screening outcomes is completed using GC/MS, GC/MS/MS or LC/MS/MS methods. Prior to confirmation, all presumptive positives undergo washing as needed. Every facet of the lab process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", the analysis actually examines the hair strand rather than the follicle beneath the scalp
In Selma, OR, hair follicle testing is preferred for its reliability and longer detection periods compared to urine tests. Hair tests minimize false negatives and ensure accurate drug use histories over a longer span, offering insights beyond standard urine tests.

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.
