Accredited Drug Testing provides comprehensive hair follicle drug screenings in Carter, Tennessee. For those needing hair drug or alcohol analyses, we at Accredited Drug Testing have expertise in hair evaluations, operating centers nationwide to conduct such tests. Typically, you need 1.5 to 2 inches of hair on your head or body, which is often suitable for use. These hair tests can reveal drugs, alcohol/ETG, or other specific testing regimens.
In recent developments, the approach to drug screening has increasingly involved hair follicle testing. Many workplaces, judicial systems, and substance abuse consultants now prefer hair drug tests over the traditional urine analysis. Employers with strict no-drug policies, the legal system, and those on probation often utilize hair follicle drug tests. The key advantage of these tests is their extended detection window for identifying drug use, typically lasting up to 90 days, gathered through a supervised procedure, greatly reducing the chance of tampering. Nevertheless, for detecting recent drug use within five days, urine tests remain the most precise.

Hair evaluations play a significant role in identifying substance use for both drugs and alcohol. The structure of hair holds biomarkers, preserving a detailed history of intake. Close-to-scalp hair samples can reveal drug and alcohol usage for nearly three months. The procedure of collecting hair is straightforward, presents challenges for tampering, and facilitates easy transport.
A sample measuring 1.5 inches, consisting of about 200 hair strands (roughly equivalent to a #2 pencil) taken nearest to the scalp represents 100mg, which is optimal for both screening and confirmation. If testing involves EtG, additional panels, or exceeds 10 panels, 150mg of hair is recommended. Using a jeweler’s scale is advisable for weighing the sample. When scalp hair isn't present, a similar quantity of body hair can be obtained. The term head hair specifically denotes scalp hair, while body hair encompasses all other types (such as facial or axillary hair).
Process Overview
There are four core phases in laboratory drug test processing: Accessioning, Screening, Extraction, and Confirmation.
Accessioning integrates a sample into the lab’s workflow. This phase includes ensuring the sample's proper sealing and delivery, assigning it a LAN (Laboratory Accessioning Number), and completing additional details not captured by automated systems.
Screening presents a preliminary assessment to detect drug use. Although Screening economically eliminates negatives in most samples, verified confirmation is essential for legal validity. A second confirmation is necessary for any sample perceived positive during Screening.
Presumptive positives from Screening undergo further hair extraction from the original sample for the Extraction phase. Here, drug collection from hair occurs at significantly lower levels than other methods (e.g., urine or oral fluids), contributing to the complexity of hair drug testing.
To verify positive Screening outcomes, methods like GC/MS, GC/MS/MS, or LC/MS/MS are employed. Pre-confirmation, all presumptively positive samples undergo washing as needed. Every phase from Accessioning to Confirmation is scrutinized based on both CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 accreditation.

Note: Despite the term "hair follicle tests" being commonly used, the process examines the hair strand, rather than the follicle situated under the skin.

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.

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.
