Whether you're in need of a hair drug or alcohol screening, Accredited Drug Testing is an expert in this field, providing services in all cities nationwide. Typically, 1.5 to 2 inches of hair from the head or body is required. These tests can detect drugs, alcohol/ETG, or can be customized to various testing options.
Over recent years, the incorporation of hair follicle drug tests has become more prevalent during drug screenings. Various employers, judicial systems, and substance abuse experts now favor hair testing over the traditional urine test. Hair follicle evaluations assist strict drug-use policies, legal entities, and those on probation. The main advantage of such tests is their extensive 90-day drug detection window, alongside being observed during collection, significantly reducing the potential for evasion. However, for identifying drug use within the preceding five days, urine testing remains most effective.

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 recognized as an effective method for identifying drug and alcohol usage. Hair archives a prolonged timeline of alcohol and drug consumption by embedding biomarkers within the fibers of actively growing hair strands. When sampled near the scalp, hair can offer a detection period of up to around 3 months for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.
A 1.5-inch segment comprising roughly 200 hair strands (approximately the girth of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample size for both initial screening and subsequent confirmation. For EtG, additional screens, and/or tests exceeding 10 panels, 150mg of the sample is advised. We advocate using a jeweler’s scale for precise specimen measurement. In cases where scalp hair is not accessible, an equivalent portion of body hair can be gathered. When mentioning head hair, we specifically refer to scalp hair. Body hair, in contrast, includes all non-scalp hair types (like facial or axillary hair).
Process Overview
The laboratory processing for a drug test outcome consists of four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initiating the sample within the lab's system. This step entails confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing data absent from an electronic chain of custody record.
Screening serves as a preliminary assessment for potential drug presence. Although Screening is a cost-friendly approach to eliminate drug use suspicion for most samples, any positive results necessitate confirmation for legal validity. Samples that test presumptively positive during Screening must undergo secondary confirmation.
Should a sample test presumptively positive during Screening, further hair is extracted from the collected sample and readied for Extraction. During this step, drug traces are extracted from hair at significantly lower concentrations compared to alternative methods (e.g., urine or saliva), explaining why hair drug testing is among the most labor-intensive methods.
To confirm a positive screening outcome, analyses like GC/MS, GC/MS/MS, or LC/MS/MS are utilized. All samples with presumptive positive results undergo washing before confirmation if necessary. The complete laboratory process, from Accessioning through Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Limitations:
Note: Although commonly termed as "hair follicle tests", the analysis is actually conducted on the hair strand rather than 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.
