Hair Follicle Drug Testing - Polk, PA

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. By embedding biomarkers within the strands, hair chronicles long-term exposure to substances. A sample cut close to the scalp can offer a detection span of up to three months for both drugs and alcohol. Collecting hair is straightforward, not easily manipulated, and convenient to ship.

A preferred sample consists of a 1.5-inch length of roughly 200 hairs (equivalent to a #2 pencil), typically weighing around 100mg, optimal for both initial screening and verification. For comprehensive tests beyond ten panels or EtG, a weight of 150mg is advised. It is suggested to measure the sample using a jeweler’s scale. If unavailable, body hair may substitute. "Head hair" pertains exclusively to scalp hair, while "body hair" includes all other types (e.g., facial, axillary).

Process Overview

The laboratory processing of drug test results includes four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the introductory stage, where a sample enters the lab’s system. This stage encompasses confirming the sample's proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and completing any missing details not provided by an electronic chain of custody system.

Screening provides a rapid initial evaluation for substances of abuse. Although Screening effectively eliminates drug usage prospects across most samples, a positive finding mandates confirmation for legal validity. Samples with presumptive positive outcomes from Screening necessitate secondary confirmation.

Once a sample is deemed presumptively positive during Screening, additional strands are extracted from the primary sample for Extraction. This process involves isolating drugs from hair at lower concentrations compared to other media (such as urine or oral fluids), highlighting the complexity of conducting hair drug screening.

Verification of a positive Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive results undergo washing before confirmation if necessary. This entire laboratory procedure, from Accessioning to Confirmation, undergoes rigorous inspection under both the CAP (College of American Pathologists) Hair categorization and the ISO/IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug use spanning up to 90 days, unlike urine tests with a briefer detection frame.
• Resistance to manipulation: Altering hair drug test outcomes is challenging, ensuring more accurate results.
• Historical insight: It reveals trends in drug use over time, beyond recent consumption.

Limitations:

• Inability to identify recent usage: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests generally cost more than alternative methods.
• Result variability: Elements like hair color and personal differences in hair growth may influence drug metabolite concentrations.

Note: Often termed "hair follicle tests," the actual analysis concerns 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.
