Hair Follicle Drug Testing - Manchester, MI

What it is, How it works

Hair analysis has gained recognition as an effective means for discovering drug and alcohol consumption. The fibers within growing strands of hair capture biomarkers, rendering a prolonged history of substance use. When the hair is collected near the scalp, it can reveal up to a 3-month period of drug and alcohol history. Collecting hair is straightforward, challenging to tamper with, and convenient to send.

A sample measuring 1.5 inches and consisting of around 200 hair strands (comparable to the width of a #2 pencil) nearest the scalp yields 100mg of hair, deemed the ideal quantity for testing and verification. For EtG, additional panels, and tests beyond 10 panels, a 150mg specimen is ideal. We advise using a jeweler's scale for weighing the sample. Should scalp hair be unavailable, a similar amount of body hair may be gathered. References to head hair exclusively pertain to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

Four key phases constitute the laboratory handling of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial sample processing into a laboratory's system, verifying proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and performing any data entry not covered by an electronic chain of custody system.

Screening involves a preliminary rapid assessment for drug abuse. While Screening is a cost-effective method to exclude drug use in most samples, positive results require confirmation for legal admissibility. Any Screening-positive samples necessitate subsequent confirmation.

If presumptive positivity occurs at the Screening stage, additional hair is extracted from the initial sample and prepared for Extraction. Here, drugs are withdrawn from hair at concentrations significantly lower than in other methodologies (e.g., urine or oral fluid), which complicates hair drug testing.

Confirmation of Screening-positive results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The comprehensive lab process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection span: Hair testing can reveal drug usage up to 90 days, whereas urine tests cover a shorter timeframe.
• Low tamper risk: Cheating a hair test is notably difficult, enhancing result reliability.
• Chronological data: It shows a timeline of drug use behavior, beyond recent consumption.

Limitations:

• Recent use not detectable: Drugs take about 5-7 days to appear in hair.
• Expense: Hair testing is typically costlier than alternative testing methods.
• Result variances: Hair color and personal hair growth differences can influence metabolite concentrations.

Note: Though often described as "hair follicle tests", the procedure examines the hair strand rather than the 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.
