Hair Follicle Drug Testing - Larchwood, IA

What it is, How it works

Hair testing is now regarded as a robust method for detecting drug and alcohol consumption. Hair provides an extended timeline of alcohol and drugs by encapsulating biomarkers within the fibers of the growing hair shaft. When gathered near the scalp, hair offers a detection span of up to approximately three months for alcohol and drugs. Hair collection is straightforward, fairly resistant to tampering, and convenient for shipping.

A 1.5-inch segment of roughly 200 hair strands (about the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimum sample for initial screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is absent, an equivalent amount of body hair may be used. By head hair, we mean scalp hair exclusively. Body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The four key steps in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory’s workflow. This involves validating the proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not furnished by an electronic chain of custody system.

Screening provides a preliminary rapid assessment for drugs of abuse. While Screening reliably excludes drug usage in most instances, a positive screen must be confirmed for court admissibility. Any samples that are tentatively positive in Screening require a follow-up confirmation.

Upon a presumptively positive outcome in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than in alternative methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair category and the accreditation to ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a more limited detection period.
• Resistance to tampering: It is extremely challenging to deceive a hair drug test, resulting in more reliable outcomes.
• Provides historical insight: It can illustrate a trend of drug use over time, not merely recent consumption.

Limitations:

• Cannot detect immediate use: Approximately 5-7 days are required for drugs to become detectable in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Elements such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although often called "hair follicle tests", the test analyzes 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.
