Accredited Drug Testing offers comprehensive hair follicle drug testing services in Central, Tennessee. For those requiring a hair test for drugs or alcohol, Accredited Drug Testing is a leader in this field, with nationwide centers skilled in conducting hair tests. Typically, 1.5 to 2 inches of hair on the scalp or body can be used. Hair tests can detect drugs, alcohol/ETG, along with other tailored testing options.
Recently, the trend in drug testing has increasingly shifted towards hair follicle drug tests. Many employers, judicial systems, and substance abuse specialists now prefer hair tests over traditional urine tests. Companies that enforce strict no-drug-use policies, along with courts and probation offices, often opt for hair follicle tests. A significant advantage of these tests is their extended detection window for drug use—generally up to 90 days. The process is observed, making it almost immune to tampering, though urine tests remain the most accurate for detecting usage within a recent 5-day frame.

Hair examinations are increasingly recognized as an effective method for identifying drug and alcohol consumption. The hair provides an extended record of substance intake by incorporating biomarkers within the strands of hair as it grows. Hair samples taken near the scalp can offer a detection timeline of roughly up to 90 days for alcohol and drugs. This method of collection is straightforward, resistant to tampering, and convenient for transportation.
A sample measuring 1.5 inches, consisting of about 200 hair strands (similar in width to a #2 pencil), taken nearest the scalp, amounts to 100mg, which is optimal for both screening and confirmation. For tests like EtG and others extending beyond 10-panel screenings, a 150mg specimen is advisable. It's suggested to measure the sample using a jeweler’s scale. If head hair is not present, an equivalent sample of body hair might be used. 'Head hair' refers exclusively to scalp hair, while 'body hair' includes all other types (facial, axillary, etc.).
Process Overview
The laboratory evaluation of a drug test comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary intake of a specimen into the lab's infrastructure. This step verifies correct sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing information not covered by an e-chain of custody system.
Screening performs an initial cursory examination for substances of abuse. Though cost-efficient, this step identifies drug presence in many samples. However, all positive screens must undergo confirmation prior to legal use. Samples with presumptive Screening positives necessitate a subsequent confirmation.
When Screening indicates presumptive positivity, further hair is extracted from the original batch and prepared for Extraction. This phase isolates drugs from hair at lower concentrations than other methods (e.g., urine or oral fluids), making hair testing a complex analytical procedure.
Confirming any Screening positivity is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Samples requiring confirmation are cleansed as necessary before analysis. From Accessioning through Confirmation, the entire testing process adheres to the CAP (College of American Pathologists) Hair protocols and aligns with ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed "hair follicle tests", these screenings analyze the strand itself, excluding the follicle under the scalp.

The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
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.
