In Holliday, Missouri, Accredited Drug Testing offers thorough hair follicle drug assessments. Whether you're seeking a drug or alcohol test through hair sampling, our specialists are proficient in this domain. We operate multiple centers across all major cities nationwide to facilitate hair tests. Typically, 1.5 to 2 inches of head or body hair is essential for testing, which can detect drugs, alcohol/ETG, and also be tailored for other testing requirements.
Hair follicle testing has grown in popularity recently for drug evaluations, replacing the conventional urine test. This shift is seen among employers with stringent anti-drug policies, judicial systems, and probation officers. The primary allure of hair tests is their ability to identify drug use over a period extending to 90 days, collecting samples under supervision, making it almost uncheatable. However, urine tests remain more precise for recent drug usage within the past 5 days.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a detailed timeline of substance use by encapsulating biomarkers within the fibers of the strand as it grows. When clipped near the scalp, hair can offer insights into alcohol and drug use for a period of up to roughly 3 months. Hair is easy to obtain, relatively resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches with roughly 200 strands (comparable to the thickness of a #2 pencil) when cut closest to the scalp yields 100mg, the perfect quantity for both preliminary and confirmatory analysis. For EtG, additional testing, or evaluations exceeding 10 panels, a sample of 150mg is advisable. It's suggested to weigh the sample using a jeweler’s scale. Should scalp hair be insufficient, an equivalent sample from body hair can be used. Note: 'head hair' refers exclusively to scalp hair, while 'body hair' includes all other types (such as facial, and axillary hair).
Process Overview
The four fundamental phases in lab processing of a drug testing result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the first level of sample processing into a lab’s framework. This step involves checking that the sample was secured and transported effectively, labeling it with a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody system.
Screening constitutes an initial rapid assessment for drug presence. Although it is an economical approach to exclude drug use across most samples, a positive screen must be verified for validity in a legal context. Samples that are presumptive positives in Screening must undergo additional confirmation.
For samples that yield a presumptive positive in the Screening step, more hair is taken from the existing sample and readied for Extraction. Here, substances are isolated from hair at concentrations much lower than those found in other test samples (like urine or oral fluids), which accounts for the complexity of performing hair drug testing.
Confirmation of any positive screening result is performed with methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation where necessary. The comprehensive lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although frequently called "hair follicle tests," the evaluation inspects the hair strand, not the follicle located 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.
