We are experts in hair assessments and provide services across numerous cities nationwide. You'll need 1.5 to 2 inches of hair from your scalp, or body hair can be an alternative. Hair tests are customizable for drugs, alcohol/ETG, and other needs.
Hair follicle drug testing has surged in popularity recently for screening. Courts, employers, and substance abuse professionals now prefer hair drug tests over the usual urine assays. These tests serve employers with zero-tolerance policies and courts managing probation.

Hair sampling is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged timeline of substance intake by embedding biomarkers within the strands as they grow. When taken from near the scalp, hair can offer nearly a 3-month analysis period for alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (roughly equivalent to the thickness of a #2 pencil) from the scalp, yields 100mg of hair, the optimal quantity for both screening and confirmation. For tests involving EtG, additional substances, and/or beyond 10 panels, 150mg of hair is advised. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair cannot be obtained, an equivalent volume of body hair may be used. When mentioning head hair, we mean exclusively scalp hair. Body hair encompasses all other hair varieties (facial, armpits, etc.).
Process Overview
The key phases in laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This involves ensuring the sample is appropriately sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not supplied by an electronic chain of custody system.
Screening involves a preliminary rapid check for substances of misuse. Screening is an economical method to exclude drug use in most samples, but a positive result requires confirmation for legal acceptability. Any samples with a presumptive positive outcome in Screening necessitate a secondary verification.
If a sample tests presumptively positive during Screening, further hair is extracted from the initial sample for the Extraction phase. At this point, substances are removed from the hair at a much lower concentration than in other testing methods (e.g., urine or oral fluid), which is why hair drug screening presents the greatest methodological challenge.
Verification of any screening-positive result is carried out through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positives undergo a washing process before confirmation if necessary. The comprehensive laboratory sequence from Accessioning to Confirmation is assessed following both the CAP (College of American Pathologists) Hair category and the ISO / IEC 17025 accreditation.

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.
