Accredited Drug Testing provides comprehensive hair follicle analysis for drug detection in Philadelphia, Pennsylvania. For those requiring a hair or alcohol test, Accredited Drug Testing excels in this field, with testing centers nationwide prepared to administer hair assessments. Generally, 1.5 to 2 inches of hair from the head or body is needed for testing. Hair evaluations can check for drugs, alcohol/ETG, or other tailored options.
In recent times, hair follicle drug assessments have become a preferred method for drug evaluations. More employers, courts, and substance abuse professionals now favor hair over traditional urine testing. Hair follicle analysis is ideal for employers with strict drug policies, judicial systems, and probationers. This method's key advantage is its extended detection period, up to 90 days, with observation during collection, making manipulation nearly impossible. However, urine tests remain the best option for identifying recent drug use within five days.

Hair testing is recognized as a notable method for identifying drug and alcohol usage. Hair captures a comprehensive historical record of alcohol and drugs by embedding biomarkers within the strands as they grow. When sourced near the scalp, hair can represent up to an estimated 3-month detection window for drugs and alcohol. It is straightforward to collect, relatively tamper-resistant, and convenient to transport.
A sample of about 1.5 inches, consisting of approximately 200 strands (similar to the girth of a #2 pencil) close to the scalp, yields 100mg of hair, serving as the optimum amount for screening and confirmation. For tests like EtG or those exceeding 10 panels, 150mg of the sample is advisable. It's suggested to assess the sample's weight using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair is acceptable. "Head hair" pertains exclusively to scalp hair, whereas "body hair" refers to other types of hair (such as facial or axillary).
Process Overview
There are four primary stages in processing a drug test result in a lab: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary integration of a sample into a lab's system, including checking that it was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and accomplishing any additional data entry absent from an electronic chain of custody system.
Screening entails an initial swift evaluation for drug abuse. While it's an economical approach for excluding drug usage in most samples, positively screened samples must be validated for credibility in legal proceedings. Mindful that any presumptive positives from Screening need verification through a secondary confirmation.
Upon a presumptive positive result during Screening, additional hair from the initial sample is readied for Extraction. This phase involves retrieving drugs from hair at a lower concentration relative to other techniques (e.g., urine or oral fluid), which underscores the challenge in conducting hair drug screening.
Positive screening confirmations are executed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as required. The entire lab process from Accessioning through Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and is held to the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Though often termed "hair follicle tests", the assessment itself examines 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.

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.
