Hair Follicle Drug Testing - Mamaroneck, NY

What it is, How it works

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged profile of substance use, encapsulating biomarkers within the hair shaft as it grows. Collected strands near the scalp can reveal an alcohol and drug detection period extending up to approximately three months. The collection process is straightforward, with minimal risk of tampering, and shipment is convenient.

Acquiring about a 1.5-inch sample of roughly 200 hair strands (equivalent to the width of a #2 pencil) nearest to the scalp provides 100mg of hair, which is optimal for analysis and verification. For EtG, additional substances, and tests exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler's scale for weighing the specimen is advised. Should scalp hair be inaccessible, a comparable amount of body hair may be gathered. When specifying head hair, we refer exclusively to scalp hair. Conversely, body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial sample integration into a laboratory system, confirming proper sample sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any missing data entry not supplied by an electronic chain of custody system.

Screening is a preliminary rapid assessment for drug abuse indications. Although Screening is an economical method to dismiss drug presence in most samples, confirming a positive result is necessary for legal admittance. Positive indications during Screening necessitate subsequent validation.

When a sample shows presumptive positivity during the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In this phase, drug residues are isolated from hair at relatively lower concentrations compared to other methodologies (e.g., urine or oral fluid), illustrating why hair drug testing is the most intricate method to execute.

Positive results from Screening are validated using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before validation as required. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes examination under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug usage up to 90 days, outlasting urine tests with shorter detection periods.
• Low susceptibility to falsification: Manipulating a hair drug test is notably challenging, enhancing result precision.
• Tracks substance use history: It outlines a drug use pattern over time, unlike tests limited to recent consumption.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug testing tends to be costlier than alternative drug testing procedures.
• Result variability: Elements such as hair color and personal differences in hair growth may influence drug metabolite concentration in hair.

Note: Despite being commonly called "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle and traditional urine tests in Mamaroneck, NY, the former consistently demonstrates superior accuracy. Hair testing offers a much more reliable detection window, uncovering substance use that urine tests might miss.

Extended Detection Window

Hair follicle tests in Mamaroneck, NY provide an extended detection window, capable of identifying drug use up to 90 days prior. This gives employers comprehensive insights into an applicant's or employee's substance history.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

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.
