Hair Follicle Drug Testing - Pinckneyville, MS

What it is, How it works

Hair analysis has emerged as a robust instrument for detecting substance and alcohol usage. Hair offers an extensive timeline of drug and alcohol exposure by embedding biomarkers in the fibers of the hair as it grows. When taken from near the scalp, hair reveals up to an approximate three-month period for the discovery of alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.

A 1.5-inch sample of around 200 hair strands (comparable to the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is the ideal quantity for testing and confirmation. For EtG, additional tests, or for test panels exceeding 10, 150mg of the specimen is advised. It is suggested to measure the specimen using a jeweler’s scale. If head hair isn't available, a similar quantity of body hair can be used. In context, head hair specifically refers to scalp hair, whereas body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The four primary phases in lab processing a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial handling of a sample into a lab’s database. This encompasses ensuring the sample was secured and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.

Screening serves as a preliminary swift check for drugs of abuse. Although Screening is a budget-friendly method to exclude drug use in most samples, a positive result must be validated to be court-admissible. Samples presumed positive in Screening necessitate a subsequent confirmation.

If Screening suggests a sample is positive, more hair is extracted from the original sample for Extraction. In this phase, drugs are removed from hair at significantly lower concentrations than other techniques (such as urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation for any positive screening outcome is carried out using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and meets the ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection period: Hair tests can detect drug usage for up to 90 days, whereas urine tests have a shorter detection timeframe.
• Hard to manipulate: It is challenging to alter a hair drug test outcome, enhancing result precision.
• Historical usage data: It can reveal a pattern of drug use over a duration, beyond just immediate usage.

Drawbacks:

• Not for recent use detection: Drugs take about 5-7 days to appear in hair.
• Expense: Hair drug tests usually cost more than other methods of drug testing.
• Result variability: Elements such as hair color and personal differences in hair growth can influence drug metabolite levels in the hair.

Note: While often termed "hair follicle tests", the analysis itself assesses the hair strand, not the root 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.
