Hair Follicle Drug Testing - Kohatk, AZ

What it is, How it works

Hair testing has emerged as a potent method for identifying drug and alcohol usage. Hair captures a prolonged record of alcohol and other substances by encasing biomarkers in the strands as they grow. When hair is gathered near the scalp, it offers nearly a 3-month period of detection for alcohol and substances. Collecting hair is straightforward, somewhat resistant to tampering, and convenient for shipping.

A 1.5-inch segment comprising roughly 200 hairs (approximately the size of a #2 pencil) near the scalp yields 100mg of hair, the preferred sample amount for both screening and confirmation. For EtG, added tests, and/or panels exceeding 10, 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing the sample. In the absence of scalp hair, an equal measure of body hair is acceptable. When discussing head hair, it specifically means scalp hair only. Body hair encompasses all other hair types (facial, underarm, etc.).

Process Overview

The laboratory processing of a drug test result comprises four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the sample's initial integration into the laboratory system. This process confirms that the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not provided by an electronic chain of custody framework.

Screening entails a preliminary and swift assessment for substances of abuse. While it is cost-efficient to exclude substance use in most samples, a positive screen must be corroborated for legal acceptance. Any samples potentially positive in Screening necessitate a subsequent confirmation.

For samples potentially positive during Screening, additional hair is extracted from the original sample and processed for Extraction. During Extraction, drugs are isolated from hair at significantly lower levels than in other approaches (such as urine or oral fluid), which underscores why hair drug screening is notably challenging.

Confirmation of any positive Screening outcome is realized using GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive are washed before confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes review compliant with both the CAP (College of American Pathologists) Hair classification and standards of accreditation under ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can trace drug use for up to 90 days, unlike urine tests which have a briefer detection period.
• Hard to manipulate: Cheating a hair drug evaluation is quite challenging, enhancing result accuracy.
• Supplies historical insights: It offers a timeline of drug usage across a duration, rather than just recent usage.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair roughly 5-7 days after use.
• Cost: Hair drug evaluations generally incur higher expenses than alternative testing strategies.
• Result variability: Aspects such as hair color and personal hair growth variances can impact drug metabolite levels in hair.

Note: Even though often termed as "hair follicle tests", the test examines the hair strand and not 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.
