When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is now viewed as an effective means for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of alcohol and substance usage by capturing biomarkers within the fibers of the growing hair strand. When taken near the scalp, this method can reveal alcohol and drug use over roughly a 3-month period. Collecting hair is straightforward, challenging to tamper with, and easily transported.
A 1.5-inch length comprising around 200 strands (equivalent to a #2 pencil’s thickness) closest to the scalp will yield 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional analyses, and/or evaluations exceeding 10 panels, 150mg is advised. Accurate weighing of the sample on a jeweler’s scale is suggested. Where scalp hair cannot be obtained, a similar quantity of body hair can be used. Head hair specifically refers to scalp hair, whereas body hair includes facial, axillary, and other types.
Overview of the Process
The primary steps in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the lab’s system. This process includes confirming the proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not provided by the electronic chain of custody system.
Screening consists of an initial rapid assessment for drug abuse. While Screening offers a cost-efficient method for excluding drug use in most samples, a positive screen requires confirmation to be legally admissible. All presumptive positive samples from Screening must be confirmed through additional analysis.
When a sample appears positive in the Screening phase, more hair is separated from the original specimen for Extraction. During Extraction, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
For any screening results that show positivity, Confirmation employs techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive specimens are cleaned before confirmation if necessary. The entire lab process from Accessioning through to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Drawbacks:
Note: Though commonly termed "hair follicle tests", it is the hair strand that is analyzed, not the follicle beneath the scalp.

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.
