Accredited Drug Testing offers comprehensive hair follicle drug assessments in Uncertain, Texas. If you're in need of hair-based drug or alcohol testing, we excel in hair analysis with locations across every major city nationwide. Typically, 1.5 to 2 inches of hair on the crown or other body hair is necessary. Our tests are capable of identifying drugs, alcohol/ETG, and can be tailored for specific testing needs.
Recently, hair follicle drug tests have become increasingly common in drug screening practices. Numerous employers, the judiciary, and substance abuse specialists now favor hair tests over traditional urine tests. Employers with strict anti-drug policies, courts, and probationers frequently rely on this method. Hair follicle tests provide an extended detection window, up to 90 days, through an observed collection, making tampering highly unlikely. Nevertheless, for recent drug use within the last 5 days, urine tests remain superior in accuracy.

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair can capture a long-term record of substance use by embedding biological markers within the hair strands as they grow. When strands are gathered near the scalp, they can offer a detection period of up to about three months for alcohol and drugs. Hair collection is straightforward, relatively secure from tampering, and convenient to transport.
A 1.5-inch sample, consisting of around 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp, yields 100mg of hair—ideal for testing and confirming. For testing involving EtG, add-ons, and/or more than 10-panel screenings, 150mg is suggested. Using a jeweler’s scale to weigh the sample is advisable. Should scalp hair be unavailable, an equivalent weight of body hair may be used. The term 'head hair' specifically applies to scalp hair, whereas 'body hair' includes all other kinds (facial, axillary, etc.).
Process Overview
Processing a drug test result in a laboratory generally includes Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample is initially entered into a laboratory’s system. This process involves confirming that the sample was properly sealed and delivered, generating a random LAN (Laboratory Accessioning Number), and completing any outstanding data input not covered by an electronic chain of custody system.
Screening serves as a preliminary evaluation for drug residues. Though Screening is an economical technique for eliminating drug use in most samples, results must be confirmed to be considered valid in legal settings. Samples indicating potential drug presence in Screening necessitate follow-up confirmation.
Should a sample indicate probable drug presence during Screening, additional hair from the original sample is set aside for Extraction. During Extraction, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluids), which contributes to the complexity of hair drug screening.
Verification of positive screenings is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo washing before confirmation where necessary. The entire procedure from Accessioning through Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Benefits of hair drug testing:
Drawbacks:
Note: Frequently labeled as "hair follicle tests," the test actually examines the hair strand 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. 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.
