Hair Follicle Drug Testing - Grand Tower, IL

What it is, How it works

Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive history of substance use by capturing biomarkers within the strands as they grow. By acquiring hair near the scalp, it offers a detection span of roughly three months for both alcohol and drugs. Hair sampling is straightforward, relatively tamper-resistant, and convenient for transportation.

A 1.5-inch section comprising approximately 200 hair strands (similar in size to a #2 pencil) from the scalp delivers 100mg of hair, the optimal quantity for both screening and verification. For EtG, enhancements, or tests exceeding 10 panels, a 150mg sample is preferred. Utilizing a jeweler’s scale to weigh the sample is advisable. Should scalp hair be inaccessible, an equivalent amount of body hair is acceptable. When we mention head hair, it exclusively implies scalp hair, while body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The fundamental stages in the lab processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a lab’s database. It involves confirming the sample's proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and fulfilling any additional data requirements not covered by an electronic custody chain system.

Screening involves a preliminary rapid assessment for drug abuse. While Screening is a cost-efficient approach to exclude drug use for most samples, a positive result necessitates confirmation to be valid in legal settings. Any presumptive positive Screening findings require subsequent confirmation.

If a sample yields a presumptive positive result during Screening, additional hair from the original sample is extracted for further analysis. In this process, drugs are extracted from hair at considerably lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging technique to execute.

Verification of positive screening results employs GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples undergo washing prior to confirmation if required. The complete laboratory procedure from Accessioning to Confirmation is assessed 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 assessments can identify drug use for up to 90 days, unlike urine tests which have a shorter detection interval.
• Hard to manipulate: Cheating a hair drug test is quite challenging, enhancing the accuracy of results.
• Offers historical insights: It can reveal a timeline of drug usage, not just recent activity.

Limitations:

• Inability to identify recent usage: It generally takes 5-7 days for drugs to be traceable in hair.
• Cost implications: Hair drug tests tend to be more costly compared to other drug testing techniques.
• Result variability: Factors like hair color and personal differences in hair growth may influence the levels of drug metabolites within the hair.

Note: Despite frequently being termed "hair follicle tests", the assessment focuses on the hair strand, not the follicle residing 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.
