Hair Follicle Drug Testing - Del Mar Woods, IL

What it is, How it works

The perception of hair testing has evolved into recognizing its effectiveness in identifying drug and alcohol use. Hair captures long-term evidence of substances by embedding biomarkers within its strands as they grow. When collected near the scalp, hair can reflect substance use within a detection period extending up to roughly three months. The process of collecting hair is straightforward, challenging to tamper with, and convenient for shipping.

A sample measuring 1.5 inches, consisting of about 200 strands near the scalp, amounts to 100mg, which is an optimal quantity for both screening and confirmation tests. For EtG, additional tests, or more than 10 panels, a 150mg specimen is advisable. It is suggested to weigh the sample using a jeweler's scale. If scalp hair isn't available, equivalent body hair may be collected. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other variants (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing of a sample into the laboratory system. It verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any required data entry not supplied through an electronic chain of custody.

Screening is a preliminary rapid assessment for substances of abuse. Although cost-effective for ruling out drug presence in most samples, a positive result in Screening mandates confirmation for legal admissibility. Samples testing presumptively positive require a further step to confirm the result.

In instances where a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for the Extraction phase. At this stage, drugs are extracted from hair at a much lower concentration than with other methods (e.g., urine or oral fluid), positioning hair drug screening as a particularly challenging methodology.

Confirmation of any positive result from Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as presumptive positives undergo a washing process prior to confirmation, as required. The entire laboratory procedure, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use spanning up to 90 days, in contrast with the shorter detection period of urine tests.
• Alteration resistance: Hair drug tests are notably difficult to manipulate, resulting in more reliable outcomes.
• Historical pattern recognition: It allows for detection of drug use patterns over time rather than merely recent ingestion.

Limitations:

• Inability to detect recent usage: It generally requires 5-7 days for drugs to appear in hair.
• Higher expense: Hair drug tests tend to be costlier compared to other testing methodologies.
• Result variability: Factors like hair color and individual growth variations can influence drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests", the examination is conducted on the hair strand, 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.
