Accredited Drug Testing offers extensive hair follicle drug testing services in Harrison, Tennessee. Should you require a hair drug or alcohol test, we specialize in hair testing and provide facilities nationwide, enabling performance of hair tests in every city. Typically, 1.5 to 2 inches of hair is required from the scalp, although other body hair may suffice. Tests can determine drugs, alcohol/ETG, or accommodate other personalized hair testing preferences.
Recently, drug testing techniques have increasingly incorporated hair follicle testing. Employers, courts, and substance abuse professionals often prefer hair drug tests over the conventional urine tests. Hair follicle drug tests cater to zero-tolerance employers, judicial systems, and probationary scenarios. Their primary advantage lies in a longer detection window—usually up to 90 days—through an observed process, with minimal risk of deception. However, urine tests remain superior for detecting recent (within five days) drug use.

Hair analysis is now acknowledged as a significant method for identifying drug and alcohol use. It offers a prolonged timeline of substance use by preserving biomarkers within the hair fiber as it grows. Hair samples taken close to the scalp can reveal drug and alcohol use for roughly up to three months. Collecting hair is straightforward, moderately challenging to tamper with, and convenient to transport.
A sample length of 1.5 inches containing roughly 200 hairs (similar in size to a #2 pencil) nearest to the scalp provides 100mg, which is the optimal quantity for both screening and verification. For tests such as EtG, additional panels, or tests exceeding 10 panels, 150mg of hair is advised. It is recommended to measure the sample using a jeweler's scale. In the absence of scalp hair, the same quantity of body hair may be obtained. By head hair, we mean hair from the scalp exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The procedure for laboratory processing of drug testing consists of four stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample in a lab's system. This step validates that the sample is properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data inputs not handled by an electronic chain of custody system.
Screening initiates a rapid check for the presence of drugs. Even though Screening is an economical method to dismiss drug use in most samples, a positive screen must be confirmed to be legally acceptable. Samples showing a presumptive positive during Screening necessitate further confirmation.
Upon a presumptive positive in Screening, additional hair is extracted from the original specimen for the Extraction process. At this stage, drugs are retrieved from the hair at significantly lower concentrations than through other testing methods (such as urine or oral fluid), which makes hair drug screening uniquely challenging.
Confirmation of positive screening outcomes is done via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if required. The entire laboratory procedure from Accessioning through Confirmation is evaluated under CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field.
