Accredited Drug Testing provides comprehensive hair follicle drug assessments in San Luis Obispo, California. Whether your requirement is for a hair drug or alcohol test, we are experts in hair analysis with facilities across all major cities in the U.S. capable of conducting such tests. Typically, you need 1.5 to 2 inches of hair, either from your scalp or body, for assessment. Hair samples can be tailored for analyzing various substances, including drugs and alcohol/ETG.
Recently, more often, drug testing has included a hair follicle approach. This method is favored by employers, judicial bodies, and addiction counselors over traditional urine tests. Employers with strict drug-free mandates, legal entities, and probation officers increasingly resort to hair follicle analysis. Its standout advantage is a duration of detection extending to about 90 days, observed while collected, and nearly cheat-proof. Nonetheless, urine tests still excel in detecting recent drug use within a 5-day frame.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair analysis has evolved into a robust method for identifying drug and alcohol consumption. The strands of hair capture biomarkers within their fibers, offering an extended timeline of drug and alcohol history. When taken near the scalp, hair can reveal usage over nearly three months for alcohol and drugs. The collection process is straightforward, less prone to tampering, and convenient to transport.
A 1.5-inch section of roughly 200 hair strands (comparable to the thickness of a #2 pencil) taken nearest the scalp will provide 100mg of hair, which is an optimal amount for both screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, it is advised to use 150mg of the sample. It's recommended to weigh the specimen using a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair may be utilized. "Head hair" is exclusively used to refer to scalp hair. "Body hair" pertains to all other hair types (including facial and axillary hair).
Process Overview
There are four principal steps in processing a drug test in the laboratory: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the laboratory's system. This step ensures that the sample was correctly sealed and dispatched, a random LAN (Laboratory Accessioning Number) is assigned, and any additional data not captured by electronic systems is inputted.
Screening consists of an initial rapid assessment for drug abuse. While Screening is economical for dismissing drug use on most samples, a positive result requires verification for legal acceptability. Samples with presumptive positives in Screening demand a subsequent confirmation step.
For samples that test as presumptive positives during Screening, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are isolated from hair at much smaller concentrations compared to other methods (e.g., urine or saliva), which makes hair analysis the most intricate to conduct.
Verification of any positive screen is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleaning prior to confirmation as required. The complete laboratory procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.

Note: Although often called "hair follicle tests", the assessment focuses on the hair strand rather than 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.
