Hair Follicle Drug Testing - Ventana, AZ

What it is, How it works

Seen as a robust tool for spotting drug and alcohol consumption, hair testing offers an extended overview of substance use by capturing biomarkers within the fibers of a growing hair strand. When gathered near the scalp, it can extend to roughly a three-month detection window for both alcohol and drugs. Hair is effortless to collect, challenging to tamper with, and simple to send.

A 1.5-inch hair sample of roughly 200 strands (comparable to the size of a #2 pencil) located near the scalp results in 100mg, which is the perfect amount for both screening and confirmation. For EtG, add-ons, and/or tests surpassing 10 panels, a specimen size of 150mg is advised. It's recommended to measure the sample with a jeweler's scale. If scalp hair cannot be obtained, an equivalent amount of body hair may be utilized. In the context of head hair, we specifically mean scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

In the lab, the process of a drug test result comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles the initial entry of a specimen into a lab’s system. This step includes verifying the sample's proper sealing and transportation, assigning it a distinct LAN (Laboratory Accessioning Number), and completing any data entry absent in an electronic chain of custody record.

Screening conducts an initial quick scan for any drugs of abuse. Although a cost-effective method to exclude drug use for most samples, a positive screening must be confirmed to hold up in court. Samples that show presumptive positives during Screening necessitate additional confirmation.

For samples appearing presumptively positive in the screening stage, more hair is pulled from the original sample for the Extraction process. This phase extracts drugs from hair at much-reduced concentrations compared to other methods (e.g., urine or oral fluid), highlighting why hair drug screening is one of the toughest methodologies.

GC/MS, GC/MS/MS, or LC/MS/MS methods carry out the confirmation of any positive screening results. Prior to confirmation, samples with presumptive positives are washed as necessary. An examination of the entire lab process from Accessioning to Confirmation is conducted under both CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug screens can identify drug usage for up to 90 days, contrary to shorter detection periods seen in urine tests.
• Resistance to tampering: It's extremely challenging to trick a hair drug test, leading to more reliable results.
• Provides usage history: This test can indicate a pattern of substance use over time, rather than just recent usage.

Limitations:

• Inability to detect recent usage: Drugs typically become detectable in hair after about 5-7 days.
• Expense: Hair drug testing is generally pricier than other methods.
• Result variances: Elements like hair color and individual hair growth variations can influence drug metabolite concentration within hair.

Note: While commonly named "hair follicle tests," the analysis is conducted on the hair strand, not the scalp’s hair follicle.

Why Hair Follicle Testing Beats Urine Testing

In Ventana, AZ, hair follicle testing is considered superior to conventional urine tests. The primary advantage is its enhanced detection accuracy and reliability.

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.
