Hair Follicle Drug Testing - Horine, MO

What it is, How it works

Widely regarded as a potent method for identifying drug and alcohol consumption, hair analysis provides an extended timeline of substance use by embedding biomarkers within the fibers of the growing strands. When cut near the scalp, hair offers approximately a 3-month detection timeline for drugs and alcohol. The process is straightforward, challenging to tamper with, and convenient for shipping.

A sample of 1.5 inches, consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp delivers 100mg of hair, optimal for screening and confirmation. For EtG, additional tests, and/or assessments exceeding 10 panels, 150mg of specimen is advised. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair isn’t accessible, a similar quantity of body hair can be taken. "Head hair" specifically means scalp hair. "Body hair" encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The key phases in a lab's drug test result processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a specimen into the laboratory’s system, which involves checking if the sample was sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and executing any extra data entry absent from an electronic chain of custody framework.

Screening comprises a rapid, initial assessment for drugs of abuse. This cost-efficient method helps to exclude drug use in most samples; however, positive results in Screening need confirmation to be legally viable in court, necessitating a secondary verification for any presumptively positive samples.

Should a sample yield a presumptive positive outcome during Screening, additional hair is retrieved from the primary specimen and readied for Extraction. At this phase, drugs are extracted from hair at a notably lower concentration than that in other methodologies (such as urine or oral fluid), which makes hair drug screening the most challenging methodology to execute.

Any positive results from Screening are verified through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive undergo washing before the confirmation if required. The entire process from Accessioning to Confirmation is evaluated 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 timeline: Hair drug tests reveal drug use up to 90 days prior, unlike urine tests with a shorter detection period.
• High accuracy: It is exceedingly hard to manipulate a hair drug test, thus the results are more reliable.
• Provides a history: It shows a trend of drug use over time, not merely recent consumption.

Limitations:

• Cannot identify recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests generally cost more than other drug testing techniques.
• Result variations: Factors like hair color and individual hair growth variations can influence drug metabolite concentrations in the hair.

Note: Although often termed "hair follicle tests", these actually examine the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Horine, MO, many are discovering why hair follicle testing outperforms traditional urine testing in drug detection. Hair tests offer superior accuracy thanks to their extensive detection window.

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.
