Hair Follicle Drug Testing - Supai, AZ

What it is, How it works

Acknowledged as a potent method for identifying drug and alcohol consumption, hair testing reveals a long-term history of substance use by encasing biomarkers within the strands as they grow. When collected from near the scalp, hair offers around a three-month detection period for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.

Acquiring a 1.5-inch sample of roughly 200 hair strands (about the girth of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the preferred quantity for both screening and confirmation. For EtG tests, add-ons, or assessments beyond 10 panels, 150mg of the sample is suggested. It is advisable to measure the sample using a jeweler's scale. Should scalp hair be inaccessible, an equivalent amount of body hair can be used. "Head hair" specifically denotes scalp hair, while "body hair" includes all other hair forms (facial, axillary, etc.).

Process Overview

The lab handling of drug test results comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the introductory processing of a sample within a lab's system. This step verifies that the sample is properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not managed by an electronic chain of custody system.

Screening performs an initial, rapid test for drugs of abuse. While it's cost-efficient for excluding drug usage in most samples, any positive Screening result must be confirmed for court validity. Samples indicating presumptive positivity in Screening require a subsequent confirmation.

When a sample tests presumptively positive in Screening, additional hair from the original collection is processed for Extraction. At this stage, drugs are extracted from hair at much lower levels than other techniques (e.g., urine or oral fluid), making hair drug screening one of the most intricate methodologies.

GC/MS, GC/MS/MS, or LC/MS/MS are used to confirm any positive screening results. Before confirmation, all presumptively positive samples are cleaned as required. This entire lab procedure from Accessioning to Confirmation is scrutinized under CAP’s (College of American Pathologists) Hair standards and complies with ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection period: Hair testing can trace drug use for up to 90 days, unlike urine tests with shorter detection frames.
• Resistance to tampering: Cheating a hair drug test is very hard, enhancing its accuracy.
• Shows patterns of use: It reflects a timeline of drug use over an extended period, not just recent use.

Limitations:

• Not effective for recent use: Drugs become detectable in hair around 5-7 days post-consumption.
• Higher cost: Hair drug testing generally incurs more costs than other methods.
• Varying results: Factors like hair color and growth differences can influence drug metabolite concentration in hair.

Note: Although often termed as "hair follicle tests", this test evaluates the hair strand itself and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Supai, AZ, hair follicle testing outshines traditional urine tests by offering superior accuracy and detection capabilities. While urine tests are limited by shorter detection windows, hair tests provide comprehensive insights into drug use over longer periods.

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.
