Hair Follicle Drug Testing - Donnellson, IL

What it is, How it works

Hair analysis is acknowledged as an effective technique for spotting drug and alcohol consumption. Hair retains a long-term record of substances by encapsulating biomarkers within the structure of the hair strand as it grows. When taken near the scalp, it offers an approximate 3-month detection timeframe for alcohol and various other substances. Hair gathering is straightforward, hard to tamper with, and convenient to transport.

A 1.5-inch segment comprising around 200 hair strands (resembling a #2 pencil's width) closest to the scalp equates to 100mg of hair, which is optimal for both screening and verification. For EtG, supplementary, and/or tests surpassing 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale to weigh the sample is suggested. Should scalp hair be inaccessible, a comparable quantity of body hair is an alternative. Head hair specifically denotes scalp hair, whereas body hair pertains to other hair categories (facial, axillary, etc.).

Process Overview

There are four cardinal phases in laboratory processing pertaining to drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the preliminary incorporation of a sample into a lab's framework. This step encompasses confirming proper sample sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data input absent from an electronic chain-of-custody system.

Screening serves as an initial rapid examination for substance abuse. Although Screening is an economical approach to exclude drug consumption for most samples, a positive result necessitates confirmation for legal validity. Any samples with presumptive positive results in Screening require further verification.

In cases where a sample yields presumptively positive results during Screening, additional hair is withdrawn from the primary sample and prepped for Extraction. Within this phase, drugs are derived from hair at significantly lower concentrations than in alternative methods (e.g., urine or oral fluid), rendering hair drug analysis the most challenging form to conduct.

Confirmation for positive Screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing before confirmation as necessary. The full laboratory undertaking from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 standard certification.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify substance use for up to 90 days, in contrast to the shorter detection timeframe of urine tests.
• Challenging to falsify: Manipulating hair drug test results is exceedingly difficult, enhancing accuracy.
• Offers historical insight: It reveals a pattern of drug use over time, not merely recent activities.

Limitations:

• Incapable of detecting recent use: It requires approximately 5-7 days before drugs are traceable in hair.
• Expense: Hair drug tests typically incur higher costs than other testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can impact drug metabolite levels in hair.

Note: Although often termed as "hair follicle tests", the examination targets the hair strand rather than the hair follicle within 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.
