For individuals in El Portal, California seeking comprehensive hair follicle drug testing, Accredited Drug Testing offers a complete solution. Specializing in hair tests across all cities nationwide, a sample generally requires 1.5 to 2 inches of hair from the crown or elsewhere on the body. Our hair testing can detect drugs, alcohol/ETG, or be customized for unique requirements.
More frequently in recent years, drug testing has incorporated hair follicle methods. Employers, courts, and substance abuse experts often prefer hair tests over urine tests. Employers with strict no-drug policies, courts, and those on probation utilize these tests because of their longer 90-day detection ability, observed collections, and low susceptibility to cheating. However, for drug use within the last 5 days, urine tests remain the most precise.

Hair analysis has been recognized as a compelling means for identifying drug and alcohol usage. The hair holds a comprehensive account of alcohol and drug consumption by encapsulating biomarkers within the hair strand as it grows. When gathered near the scalp, hair can present nearly a 3-month detection period for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and conveniently transportable.
A 1.5-inch portion comprising roughly 200 hair strands (comparable to the girth of a #2 pencil) from the scalp yields 100mg of hair, the optimal amount for screening and confirmation. For EtG, supplementary tests, and/or panels exceeding 10, a 150mg sample is advised. It’s suggested to measure the sample on a jeweler’s scale. If scalp hair isn’t obtainable, an equivalent quantity of body hair may be used. The term head hair exclusively refers to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary four steps in the lab analysis of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the foremost handling of a specimen within a lab’s framework. It includes checking that the specimen was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any leftover data input not offered by an electronic chain of custody system.
Screening serves as a preliminary rapid inspection for drug usage. Although Screening is an economical method to negate drug utilization in most samples, a positive finding requires verification to be valid in court. Samples deemed presumptively positive during Screening necessitate further confirmation.
If a sample is deemed presumptively positive during Screening, additional hair is drawn from the initial sample for Extraction preparation. During this phase, drugs are isolated from hair at significantly lower levels than other techniques (e.g., urine or oral fluid), rendering hair drug screening the most challenging technique to execute.
Verification of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive undergo washing before confirmation as needed. The entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair protocol and meets ISO / IEC 17025 accreditation standards.

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.
