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.
The application of hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair captures a prolonged record of substance use by embedding biomarkers within the fibers of the growing strands. When collected near the scalp, it offers a detection window of up to about three months for substances like alcohol and drugs. The process of collecting hair is straightforward, challenging to tamper with, and convenient for transportation.
A sample measuring 1.5 inches and consisting of roughly 200 strands (approximately the size of a #2 pencil) closest to the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG, extra tests, and/or panels exceeding 10, it is advised to collect 150mg of the specimen. It's recommended to weigh the sample using a jeweler's scale. If scalp hair isn't accessible, a similar quantity of body hair can be used. "Head hair" here specifically refers to scalp hair. "Body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
In the laboratory analysis of a drug test result, the primary steps include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a sample into the laboratory's system. This step includes ensuring the sample's proper sealing and shipping, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry that isn't covered by an electronic chain of custody system.
Screening provides a preliminary check for substances of abuse. Though Screening serves as a cost-efficient approach to rule out drug use for most samples, a court-admissible outcome necessitates confirmation of any positive screen. Consequently, samples with presumptive positive results from Screening required a second confirmation.
Should a sample be presumptively positive during Screening, additional hair is extracted and prepared for the Extraction phase. During this process, drugs are isolated at significantly lower concentrations from hair compared to other methods (e.g., urine or oral fluid), highlighting the challenge of hair drug screening.
Confirmation involves verifying any positive screening result through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptive positive undergo a washing step before confirmation, as necessary. The entire procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the accreditation under ISO / IEC 17025 standards.

Limitations:
Note: Commonly referred to as "hair follicle tests", the analysis is actually conducted on the hair strand, not the follicle below 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.
