Accredited Drug Testing offers comprehensive hair follicle drug screening services in Midtown, Tennessee. Whether you require a hair drug or alcohol test, we specialize in hair analysis and provide testing facilities in all major cities nationwide. A hair length of 1.5 to 2 inches on the head or body is typically needed. Hair testing can be conducted for drugs, alcohol/ETG, or other personalized options.
In recent times, hair follicle drug testing has become increasingly prevalent. Various organizations, judicial bodies, and substance abuse professionals now prefer this method over traditional urine tests. Employers with zero-tolerance policies, courts, and probationers rely on hair tests due to their extended detection period of up to 90 days, observed collection process, and high resistance to tampering. However, for detecting recent drug use within the last 5 days, urine tests remain most effective.

Utilizing hair tests has emerged as an effective method for identifying alcohol and drug consumption. Hair offers an extended history of substance use by embedding biomarkers within the strands as the hair grows. When gathered near the scalp, hair can indicate substance consumption over a period of up to three months. It is straightforward to collect, relatively hard to tamper with, and convenient to ship.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (around the mass of a #2 pencil), will yield 100mg, which is the peak sample for analysis and validation. For EtG, supplemental tests, or those exceeding 10 panels, 150mg is advised. It's suggested to measure the hair on a jeweler’s scale. Should scalp hair be absent, an equivalent amount of body hair is acceptable. Head hair specifically refers to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The drug testing lab procedure consists of four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning handles the initial entry of a specimen into a lab's database. It verifies proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes data entry not automatically recorded by an electronic chain of custody.
Screening performs an initial and swift assessment for drug presence. While screening serves as a cost-effective technique to dismiss drug use in most specimens, a positive result must be confirmed for legal validity. Specimens showing presumptive positivity in Screening necessitate further confirmation.
When a specimen shows presumptive positivity during Screening, additional hair is extracted from the original sample for preparation in the Extraction stage. In this phase, drug compounds are derived from hair at lower concentrations compared to other methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmatory analysis of any positive screen utilizes GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples indicated as presumptively positive undergo washing before confirmation where necessary. The comprehensive lab procedure, from Accessioning through Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Though sometimes termed "hair follicle tests", the examination pertains to the hair strand rather than the follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. 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.
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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
