Accredited Drug Testing offers comprehensive hair follicle drug assessments in Meridian, Pennsylvania. For those needing a hair drug or alcohol evaluation, Accredited Drug Testing excels in these analyses, with facilities available in every city across the nation. Typically, 1.5 to 2 inches of hair is required, either from the head or body. Hair analyses can be conducted for substances, alcohol/ETG, or other tailored testing requests.
In recent times, drug screening methods have increasingly adopted hair follicle tests. More employers, judicial systems, and substance abuse experts now prioritize hair-based evaluations over conventional urine tests. Hair follical screenings are favored by employers adhering to strict no-drug policies, courts, and probation officers. They benefit from an extensive detection window, usually up to 90 days, administered under supervision, making them hard to tamper with. Nevertheless, urine screenings still offer the highest accuracy for determining substance use within the past five days.

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 analysis has become recognized as an effective instrument for spotting alcohol and drug usage. Hair offers an extended history of drugs and alcohol by preserving biomarkers within the fibers of the expanding hair shaft. When gathered near the scalp, hair can give up to around a 3-month period of detection for substances like alcohol and drugs. Hair is straightforward to collect, somewhat challenging to adulterate, and simple to transport.
A sample 1.5 inches in length consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is the preferred amount for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is preferred. We suggest using a jeweler's scale to weigh the sample. In cases where scalp hair is not available, an equivalent amount of body hair can be used. References to head hair pertain exclusively to scalp hair, while body hair encompasses all other hair sections (facial, axillary, etc.).
Process Overview
There are four principal steps associated with lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample into the lab's system. This step includes checking if the specimen was securely sealed and correctly transported, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody.
Screening is an initial rapid check for drugs of abuse. Although Screening serves as a cost-efficient technique to dismiss drug use across numerous samples, a positive outcome must be substantiated for judicial acceptability. Samples showing presumptive positivity demand secondary confirmation.
If a specimen is deemed presumptively positive at the Screening stage, further hair is drawn from the initial batch and readied for Extraction. During this phase, drugs are drawn from hair at a much lower concentration than other methodologies (e.g., urine or oral fluid), which makes hair drug analysis the most challenging methodology to execute.
Confirmation on any positive screening results is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a wash prior to confirmation as needed. The whole lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Drawbacks:
Note: Despite being often termed "hair follicle tests", the actual examination is conducted on the hair strand and not the hair 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.
