Hair Follicle Drug Testing - Knoke, IA

What it is, How it works

The method of hair testing is increasingly recognized for its effectiveness in identifying drug and alcohol consumption. Hair captures a comprehensive history of substance use by embedding biomarkers within the expanding hair strand. Collecting hair from near the scalp can offer a detection period of approximately three months for drugs and alcohol. Hair is relatively straightforward to gather, challenging to tamper with, and convenient to transport.

A 1.5-inch hair sample comprising around 200 strands (roughly the thickness of a #2 pencil) from the scalp yields 100mg of hair, which is optimal for both screening and confirmation. When conducting tests such as EtG, add-ons, and/or those exceeding 10 panels, a specimen of 150mg is advised. It is recommended to measure the sample with a jeweler’s scale. Should scalp hair be inaccessible, an equivalent volume of body hair is an option. Scalp hair specifically pertains to head hair, while body hair includes all other varieties (facial, axillary, etc.).

Process Overview

The primary steps in laboratory handling of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a specimen into the laboratory framework. This step involves confirming the sample's appropriate sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any other data entry not covered by an electronic chain of custody system.

Screening serves as a preliminary inspection for abuse substances. Although Screening is a budget-friendly strategy to exclude drug usage in most specimens, a confirmatory test is necessary for courtroom admissibility if the screen is positive. Samples with a presumptive positive result in Screening require additional confirmation.

In cases where a sample tests presumptive positive during Screening, further hair is extracted from the initial specimen and prepped for Extraction. In this phase, substances are removed from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), which contributes to the complexity of hair drug testing.

Confirmation of any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing as part of confirmation if required. The entire laboratory procedure from Accessioning to Confirmation is conducted in compliance with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter timeframe.
• Minimal possibility for deceit: It is highly challenging to bypass a hair drug test, enhancing result precision.
• Tracks historical usage: It can chart a pattern of drug use over time, rather than just recent usage.

Limitations:

• Incapacity to spot recent use: Drugs become detectable in hair roughly 5-7 days after use.
• Price: Hair drug tests generally cost more than alternative testing methods.
• Result variances: Elements like hair color and individual growth discrepancies can influence the concentration of drug metabolites in hair.

Note: Although often referred to as "hair follicle tests", the analysis targets the hair strand itself, not the follicle under 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.
