Hair Follicle Drug Testing - Jaars, NC

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair offers a chronicled account of alcohol and drug presence by capturing biomarkers within the fibers of its growth. When obtained near the scalp, hair can reveal a detection window for alcohol and drugs extending approximately up to 3 months. Hair collections are straightforward, somewhat resistant to tampering, and convenient for shipping.

A sample of 1.5 inches, composed of roughly 200 hair strands (comparable to a #2 pencil in thickness) nearest the scalp yields 100mg, which is optimal for both screening and validation. For EtG, supplementary tests, and/or examinations beyond 10 panels, 150mg of hair is suggested. Using a jeweler’s scale for specimen weighing is advisable. If scalp hair is unavailable, an equivalent amount of body hair is an alternative. References to head hair pertain strictly to scalp hair. All other hair types (including facial or axillary hair) are referred to as body hair.

Process Overview

The laboratory process for a drug test result incorporates four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is entered into a laboratory system. It includes verifying proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and filling in any additional data missing from an electronic chain of custody system.

Screening acts as a preliminary check for illicit substances. While it offers a cost-efficient method to exclude drug use in most samples, a positive screening must be validated to be court admissible. Samples that are presumptively positive during Screening necessitate subsequent confirmation.

If a sample indicates a presumptive positive in Screening, more hair is sourced from the original specimen for Extraction, where substances are abstracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug analysis the most challenging approach.

Confirmation of positive screening outcomes is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives undergo washing prior to confirmation, as necessary. The whole laboratory process spanning from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair tests identify drug use up to 90 days, whereas urine tests have shorter detection periods.
• Hard to manipulate: Cheating a hair test is notably difficult, hence ensuring more precise results.
• Provides historical insight: It identifies a pattern of drug use over extended periods, unlike tests for recent use only.

Limitations:

• Incapable of detecting recent usage: Drugs appear in hair after an estimated period of 5-7 days.
• Expense: Hair testing tends to be pricier than alternative drug testing methods.
• Variability: Aspects such as hair color and personal hair growth variations may influence drug metabolite concentrations in the hair.

Note: Often termed as "hair follicle tests", the analysis actually examines the hair strand rather than the hair 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.
