Accredited Drug Testing provides comprehensive hair follicle drug testing services in Los Fresnos, Texas. If you're looking for a hair drug or alcohol test, we specialize in hair testing and have centers across all U.S. cities capable of conducting these tests. Generally, 1.5 to 2 inches of hair from your crown or body is required. Hair tests can detect drugs, alcohol/ETG, or offer other tailored testing options.
In recent times, drug testing frequently involves a hair follicle drug test. Many workplaces, legal systems, and substance abuse experts now prefer hair tests to standard urine tests. Hair follicle tests are favored by employers with strict drug policies, courts, and those overseeing probation. The key advantage is its longer detection span for drugs, reaching up to 90 days, and using a monitored collection method, it's nearly tamper-proof. Yet, when detecting recent drug use within five days, urine tests remain highly accurate.

Recognized for its efficacy, hair testing serves as a potent method for identifying the use of drugs and alcohol. Hair captures a prolonged timeline of substance use by embedding biomarkers within the strands as they grow. When snipped near the scalp, hair reveals a detection period extending nearly 90 days for both alcohol and other substances. Collecting hair is straightforward, difficult to tamper with, and convenient for shipping.
A snippet of 1.5 inches, approximately 200 strands (comparable to a #2 pencil), taken nearest to the scalp provides a 100mg sample, optimal for both screening and confirmation. For EtG, additions, and/or tests exceeding 10 panels, a 150mg specimen is advisable. It is recommended to measure the sample with a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair is suitable. References to head hair pertain solely to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The drug test result process entails four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial integration of a sample into the laboratory system. This step ensures that the sample’s seal and shipment are intact, assigns a random LAN (Laboratory Accessioning Number), and addresses any additional data entry absent from an electronic chain of custody.
Screening offers a preliminary, rapid assessment for drug abuses. While Screening is a cost-effective measure to dismiss drug consumption in most cases, a positive result warrants confirmation for legal admissibility. Presumptively positive Screening samples necessitate a secondary verification.
Should a sample yield a presumptive positive in the Screening phase, additional hair is extracted from the primary sample for the Extraction process. This phase involves deriving drugs from hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), explaining the challenge of hair drug testing.
Confirmation of positive results is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positives are cleansed prior to confirmation when needed. The comprehensive lab process ranging from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Often mischaracterized as "hair follicle tests", the analysis focuses on the hair strand itself, not the follicle beneath the scalp.

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. 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.
