Accredited Drug Testing offers comprehensive hair follicle drug assessments in Pasadena, Texas. If you're seeking a hair or alcohol analysis, Accredited Drug Testing excels in this type of testing with facilities in every major U.S. city equipped to administer it. For most cases, a sample length of 1.5 to 2 inches from the scalp or another body area is needed. Hair evaluations are effective for detecting drugs, alcohol/ETG, or other tailored testing requirements.
The past years have seen an increase in utilizing hair follicle drug assessments over traditional methods. Many companies, judicial systems, and substance specialists now prefer hair analysis to urine sampling. Hair follicle evaluations are favored by organizations with zero-tolerance policies, legal bodies, and those on probation. Their chief advantage is the extended timeframe for identifying drug use, often up to 90 days, performed under supervision, and difficult to manipulate. However, for testing substance intake within recent days, urine still proves most precise.

Hair testing is increasingly recognized as an effective means to identify drug and alcohol consumption. Hair retains a comprehensive timeline of alcohol and drug intake by encapsulating biomarkers in the strands of hair as it grows. When retrieved closely from the scalp, hair can offer a detection span of up to around 3 months for alcohol and drugs. Hair collection is effortless, challenging to tamper with, and straightforward to transport.
A 1.5-inch hair specimen of around 200 strands (roughly the thickness of a #2 pencil) nearest to the scalp yields 100mg, an optimal quantity for screening and corroboration. For EtG extensions, and/or assessments beyond 10 panels, a specimen amount of 150mg is advised. We suggest weighing the specimen using a jeweler’s scale. If scalp hair isn't accessible, a similar volume of body hair can be used. By head hair, we mean specifically scalp hair. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result includes four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the primary processing of a specimen into a lab’s system. This involves ensuring the sample was correctly sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and finalizing any necessary data input not covered by an electronic chain of custody system.
Screening provides a preliminary rapid assessment for substance abuse. Screening serves as an economical approach to dismiss drug usage in most samples, though a positive screen must undergo confirmation for court usability. Samples preliminarily deemed positive in Screening require further confirmation.
For samples preliminarily positive in the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. During this phase, drugs are extracted from hair at far lower concentrations than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation of any positive initial result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive receive a wash before confirmation as necessary. The full laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Note: Although commonly termed as "hair follicle tests", the assessment targets the hair strand itself 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.
