Accredited Drug Testing offers thorough hair follicle drug testing services in Nashville, North Carolina. When in need of hair drug or alcohol testing, our expertise in hair testing is unmatched, with testing locations across numerous cities nationwide capable of conducting these tests. A minimum of 1.5 to 2 inches of hair from the crown or body is generally required. Hair testing can detect drugs, alcohol/ETG, and offers customizable testing options.
In the past few years, hair follicle drug testing has become a preferred method for screening. It is now increasingly requested by employers, courts, and Substance Abuse experts instead of the typical urine test. This method is favored by companies with strict drug-free policies, judicial systems, and probation offices. Its main advantage is the extended detection timeframe of up to 90 days, starting from a supervised collection, making it difficult to deceive. Yet, for identifying recent drug use within the last five days, urine testing remains the most precise.

Hair testing has emerged as an influential tool for identifying the use of drugs and alcohol. Hair offers an enduring history of substances by encasing biomarkers within the fibers of its growing strands. Collected close to the scalp, hair provides an approximate 3-month detection window for alcohol and substances. It's easy to collect, a bit challenging to alter, and simple to transport.
A 1.5-inch sample comprising roughly 200 hairs (around the width of a #2 pencil) taken nearest to the scalp provides 100mg, the perfect amount for screening and confirmation. For EtG, additions, and/or tests beyond 10 panels, 150mg is suggested. We advocate weighing the specimen using a jeweler’s scale. If scalp hair is unavailable, an equal amount of body hair can be collected. When mentioning head hair, we specifically mean scalp hair. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The process in a laboratory drug test comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial handling of a sample in a lab's system. This includes confirming that the sample is sealed and shipped correctly, issuing a random LAN (Laboratory Accessioning Number), and finishing any additional data entry not covered by an electronic chain of custody system.
Screening entails an initial brief evaluation for abused drugs. Although Screening economically eliminates drug use in most samples, a positive result must be confirmed for courtroom acceptability. Presumptive positive samples from Screening necessitate secondary confirmation.
If a sample tests presumptively positive in Screening, more hair is extracted from the original sample for Extraction. Here, drugs are obtained from hair at reduced concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method.
GC/MS, GC/MS/MS, or LC/MS/MS are used for confirming positive Screening results. Presumptive positive samples are washed as necessary before confirmation. The comprehensive lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair standard and accreditation to ISO / IEC 17025 criteria.

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.
