Accredited Drug Testing offers comprehensive hair follicle testing services in Louisville, Tennessee. Specializing in hair drug and alcohol tests, our facilities across the nation are equipped to conduct reliable hair tests. Most individuals need 1.5 to 2 inches of hair from the scalp, although body hair might also be suitable. Hair samples can be tested for drugs, alcohol/ETG, or customized options to meet specific testing needs.
Recently, hair follicle testing has become a preferred drug testing method over traditional urine tests. Employers, judicial systems, and Substance Abuse professionals are increasingly opting for hair drug tests for their reliability and longer detection window. Hair follicle tests provide a longer detection period, capturing up to 90 days of drug use history, are collected under supervision, and are difficult to tamper with. However, urine tests remain the most precise choice for detecting drug use within the past 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.
Hair testing is recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the strands, hair documents a comprehensive history of substance use. Hair collected near the scalp can reveal alcohol and drug use over a period of up to three months. It's straightforward to collect, somewhat resistant to tampering, and easy to transport.
A length of hair measuring 1.5 inches with approximately 200 strands (the width of a #2 pencil) taken closest to the scalp yields about 100mg, ideal for preliminary screening and validation. For tests like EtG, add-ons, or those surpassing 10 panels, a sample of 150mg is advised. We suggest using a jeweler’s scale for precise measurement. If scalp hair is not available, a similar quantity of body hair is acceptable. References to head hair specifically mean scalp hair. Body hair encompasses all other hair varieties, such as facial or axillary.
Process Overview
The primary steps in laboratory assessment for drug tests are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the foundational step where a sample enters the lab system. This phase ensures the sample's proper sealing and shipment, assigns it a distinct LAN (Laboratory Accessioning Number), and completes any missing data entry not captured by an electronic custody system.
In the Screening phase, a rapid test for drugs of abuse is conducted. While cost-effective for excluding drug use in most samples, a positive Screening result requires confirmation for legal acceptability. Samples indicating a potential positive in Screening need additional verification.
For samples flagged as positive in Screening, additional hair is taken from the original sample and readied for Extraction. This step isolates drugs from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening especially challenging.
Confirmation for any positive Screening result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo a wash before confirmation as necessary. The full lab process from Accessioning to Confirmation is carefully reviewed under the CAP (College of American Pathologists) Hair designation as well as the ISO / IEC 17025 accreditation standards.

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.
