In Winnsboro, Texas, Accredited Drug Testing offers thorough hair follicle drug analysis. If you require a test for hair-borne substances, we are the experts with nationwide and local testing facilities capable of conducting hair evaluations. Generally, 1.5 to 2 inches of hair from the scalp or elsewhere on the body is required. Hair analysis can detect drugs, alcohol/ETG, and other specific testing options.
Recently, the practice of administering drug tests has increasingly utilized hair follicle analysis. Employers, courts, and substance abuse experts often prefer it over traditional urine tests. Hair follicle testing is favored by such entities due to its superior detection period, extending up to 90 days, its observed collection method, and the difficulty to tamper with it. Despite this, urine tests remain the most accurate for detecting recent drug use within the last five days.

Hair analysis is now viewed as a significant method for identifying drug and alcohol consumption. Hair captures a prolonged record of substance intake by embedding biomarkers within its strands during growth. When hair is taken near the scalp, it can offer a detection period extending up to around three months for substances. Hair is easy to collect, fairly resistant to tampering, and simple to send.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil's diameter) nearest to the scalp yields 100mg of hair, which is the optimal sample size for testing. For EtG, supplementary tests, or screenings above 10 panels, a 150mg sample is advised. It is suggested to weigh the sample with a jeweler’s scale. If scalp hair isn't available, a comparable amount of body hair is acceptable. "Head hair" specifically refers to scalp hair. "Body hair" indicates all other hair types (like facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step of integrating a sample into the lab's system. This involves confirming the sample's proper sealing and transportation, generating a random LAN (Laboratory Accessioning Number), and completing any lacking data entry not supported by an electronic custody system.
Screening serves as an initial rapid assessment for drug presence. Although Screening is a cost-efficient strategy for excluding drug use in most samples, a positive result in Screening must undergo Confirmation to be valid legally. Presumptive positives in Screening must proceed to a subsequent confirmation stage.
When a sample tests positive during Screening, additional hair from the original batch undergoes preparation for Extraction. During this step, drugs are isolated from hair at far lower concentrations than seen in alternative methods (e.g., urine or saliva), which positions hair testing as the most challenging method to conduct.
Confirmation for any positive result from screening utilizes GC/MS, GC/MS/MS, or LC/MS/MS technologies. Prior to confirmation as necessary, all presumptive positive samples receive a wash. From Accessioning to Confirmation, the entire lab process adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

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.
