Accredited Drug Testing offers thorough hair follicle drug assessments in Chesterfield, South Carolina. Seeking a hair-based drug or alcohol evaluation? Our expertise in hair testing includes nationwide facilities capable of conducting these tests. Generally, 1.5 to 2 inches of hair on your head or body is necessary for analysis, covering drugs, alcohol/ETG, or tailored testing options.
Recently, drug testing methods have increasingly relied on hair follicle tests. Businesses, judicial systems, and Substance Abuse experts now often prefer hair testing over typical urine tests. Hair tests, valued by those enforcing zero drug tolerance, probationary checks, or court directives, spotlight a broader detection window—often up to 90 days—performed under scrutiny and nearly impervious to manipulation. Nonetheless, for recent drug use within 5 days, urinalysis remains the definitive choice.

Hair analysis is now acknowledged as an effective means for identifying drug and alcohol involvement. It provides an extended-history record of substance intake by encasing biomarkers within the hair strand's evolving fibers. Hair, when clipped near the scalp, can represent a detection window of up to 3 months for alcohol and other substances. Collection is straightforward, tampering is challenging, and it ships conveniently.
To acquire an optimal sample, a 1.5-inch portion consisting of about 200 strands (equal in thickness to a #2 pencil) nearest the scalp is needed, equating to 100mg—the perfect amount for both screening and validation. For EtG, extra checks, or tests exceeding 10 panels, 150mg of the sample is advised. Use a jeweler's scale for accurate measurement. Should scalp hair be unavailable, a corresponding quantity of body hair can be utilized. Here, head hair exclusively signifies scalp hair, while body hair includes all other varieties (facial, auxiliary, etc.).
Process Overview
The laboratory procedure for a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial sample logging into a laboratory’s framework. This stage ensures the sample's seal and correct shipping, assigns a random LAN (Laboratory Accessioning Number), and finalizes any missing data not captured by an electronic chain of custody.
Screening performs an initial cursory inspection for illicit substances. Though cost-efficient for ruling out drug presence in numerous samples, positive screens require confirmation before legal admissibility. Presumptively positive samples necessitate additional verification.
Should a sample be ostensibly positive in Screening, extra hair from the original sample is prepared for Extraction. This involves obtaining drugs from hair at much lower concentrations than other techniques (e.g., urine or oral fluid) and is why hair drug testing is notably complex.
Confirmation of any positive screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are appropriately cleaned before confirmation. The complete laboratory workflow from Accessioning to Confirmation is assessed per the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 norms.

Note: Although occasionally termed "hair follicle tests", the test examines the hair strand, not 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.
