Hair Follicle Drug Testing - Lancaster, NH

What it is, How it works

Hair screenings are now regarded as a robust mechanism for detecting alcohol and drug consumption. Hair encompasses a prolonged record of substance use by capturing biomarkers within the strands of hair as they develop. When harvested close to the scalp, hair can offer roughly a 3-month window for detecting substances like alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and facilitates easy transportation.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (similar thickness to a #2 pencil) close to the scalp, yields 100mg, which is an optimal amount for both screening and confirmation. For EtG, additional analyses, or tests exceeding 10 panels, a specimen of 150mg is suggested. It is advisable to use a jeweler’s scale for accurate weighing. Should scalp hair be unavailable, a similar quantity of body hair can be utilized. In discussing head hair, our reference is specifically to scalp hair. Body hair encompasses other types, such as facial or axillary hair.

Process Overview

The primary stages in the laboratory procedure for achieving a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the initial incorporation of a sample into the laboratory's framework. This entails ensuring the sample's seal and correct dispatch, allocating a unique LAN (Laboratory Accessioning Number), and addressing any supplementary data entry absent from an electronic custody trail.

Screening incorporates an initial swift evaluation for substance abuse. Although Screening is a cost-efficient strategy to refute drug use in the majority of samples, a positive outcome mandates validation for legal acceptability. Samples marked presumptively positive during Screening necessitate additional substantiation.

If a sample is designated presumptively positive during the Screening phase, additional hair is taken from the original sample for Extraction preparation. At this juncture, drugs are extracted from hair at notably lower concentrations than found in other modalities (e.g., urine or oral fluid), rendering hair drug screening a particularly challenging methodology.

Verification of any positive results from Screening is conducted employing GC/MS, GC/MS/MS or LC/MS/MS techniques. Prior to confirmation, all presumptive positive samples undergo a washing process as necessary. The comprehensive laboratory procedure, spanning from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests are capable of detecting substance use extending up to 90 days, whereas urine tests have a more limited detection period.
• Complication to deceive: It is notably challenging to deceive a hair drug test, which enhances result accuracy.
• Offers historical insight: It provides an overview of drug use patterns over time, rather than solely recent usage.

Limitations:

• Inability to identify recent use: There is a 5-7 day latency before drugs become identifiable in the hair.
• Expense: Hair drug screens generally incur higher costs compared to alternative testing methodologies.
• Inconsistencies in findings: Variations such as hair pigmentation and individual hair growth rates can influence the metabolite concentration detected in hair.

Note: Though frequently termed "hair follicle tests", the assessment scrutinizes the hair strand rather than the follicle beneath the scalp

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.
