Hair Follicle Drug Testing - Lost Nation, IA

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug usage by embedding biomarkers in the fibers of the growing hair strand. When taken near the scalp, hair offers approximately a 3-month detection period for alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and convenient to transport.

A sample size of 1.5 inches, consisting of around 200 hair strands (roughly the diameter of a #2 pencil), near the scalp yields 100mg of hair, the preferred quantity for both screening and verification. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the sample is suggested. It is advisable to measure the sample with a jeweler’s scale. Should scalp hair be unavailable, a similar quantity of body hair may be utilized. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for a drug test result consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab’s system. This phase includes checking for proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and finishing any additional data entry not completed by an electronic chain of custody system.

Screening executes a preliminary rapid assessment for substance abuse. Although Screening is an economical method to eliminate drug use on most samples, a positive screen must be verified for legal acceptability. Any samples showing positive results in Screening demand a follow-up confirmation.

Should a sample indicate a positive result during the Screening phase, additional hair is extracted from the initial sample and processed for Extraction. In this stage, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug analysis the most challenging method to execute.

Confirmation of any positive screening outcome involves GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The full laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection duration: Hair drug tests can uncover drug use for up to 90 days, unlike urine tests with a shorter detection period.
• High resistance to manipulation: It's notably hard to manipulate a hair drug test, ensuring more precise results.
• Historical usage data: It delivers a timeline of drug use over time, not just recent consumption.

Limitations:

• Incapable of identifying recent use: Drugs require around 5-7 days to become traceable in hair.
• Higher cost: Hair drug tests typically entail greater expenses than other drug testing techniques.
• Variabilities in outcomes: Elements like hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Often referred to as "hair follicle tests", this test 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.
