In Cedar Park, Texas, Accredited Drug Testing offers comprehensive hair follicle drug testing. If hair drug or alcohol testing is required, our expertise lies in hair testing, with facilities available across all cities nationwide to conduct such tests. Typically, a hair length of 1.5 to 2 inches on the crown or body is necessary. These tests can detect drugs, alcohol/ETG, or can be tailored for other specific testing needs.
Hair follicle drug testing has become more prevalent in recent years as a method of drug testing. Employers, courts, and Substance Abuse professionals are increasingly opting for hair drug tests over traditional urine tests. For employers with zero-tolerance drug policies, courts, and probationers, the main advantage of hair follicle tests is their extended detection window, typically up to 90 days, improving reliability and reducing cheating opportunities. However, urine tests remain the most precise for recent drug use within five days.

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.
Utilizing hair testing has emerged as an effective means for detecting both drug and alcohol usage. Hair captures a comprehensive history by embedding biomarkers within the strands as they grow. When collected close to the head, it can provide a detection period of up to roughly three months for drugs and alcohol. It's easy to collect, tough to tamper with, and simple to transport.
By gathering a 1.5-inch segment of around 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp, you obtain 100mg, the optimum sample size for both screening and confirmation. For EtG, additional analyses, and/or tests beyond ten panels, a 150mg sample is preferred. We advise measuring the specimen with a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair can be obtained. By head hair, we specifically mean scalp hair. Body hair refers to everything else (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test result encompasses four critical phases: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially processed into the lab's system. This step ensures the sample was sealed and sent correctly, issues a random LAN (Laboratory Accessioning Number), and completes any outstanding data entry absent from an electronic chain of custody system.
Screening involves a prompt preliminary check for substance use. Although screening is a cost-efficient way to exclude drug use for most samples, a positive screen mandates confirmation for legal acceptability. Presumptive positives from Screening demand secondary verification.
Should a sample show presumptive positivity in Screening, more hair is collected from the initial sample for Extraction. Here, substances are isolated from hair at far lower concentrations than other methods (e.g., urine or saliva), making hair drug screening particularly complex to execute.
Any positive screening outcome is validated through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. Each laboratory step from Accessioning to Confirmation falls under the scrutiny of both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Note: Often called "hair follicle tests," the test evaluates the hair strand, not the hair follicle within the scalp

Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. 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.
