Hair Follicle Drug Testing - Bally, PA

What it is, How it works

Hair analysis has emerged as a potent instrument for detecting drug and alcohol consumption. The hair captures biomarkers within its fibers as it grows, offering a prolonged record of alcohol and drug intake. When sourced near the scalp, hair can provide an approximate three-month detection period for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and easy to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil) near the scalp yields 100mg of hair, the perfect sample size for screening and confirmation. For EtG, additional tests, or tests beyond 10 panels, a 150mg sample is advisable. It's recommended to use a jeweler's scale for weighing. If scalp hair isn't available, an equivalent amount of body hair can be gathered. When referring to head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is processed into a laboratory's system. This step includes verifying the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not supplied by an electronic chain of custody system.

Screening is a preliminary rapid check for drugs of abuse. While it is a cost-effective method to exclude drug usage in most samples, a positive screening result requires confirmation for legal admissibility. Any samples that test presumptively positive during Screening need secondary confirmation.

If Screening indicates a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. In this phase, drugs are extracted from hair at much lower concentrations than other methods like urine or oral fluid, making hair drug screening the most challenging method to execute.

Confirmation for any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The entire laboratory process, from Accessioning to Confirmation, is audited adhering to both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests detect drug usage up to 90 days, unlike urine tests with shorter detection spans.
• High resistance to cheating: Cheating a hair test is extremely challenging, resulting in more precise results.
• Historical usage insights: It reflects a drug use pattern over an extended period, rather than just recent usage.

Limitations:

• Inability to detect recent usage: Drugs take around 5-7 days to become detectable in hair.
• Cost factor: Hair tests are typically more expensive compared to other drug testing methods.
• Variability in outcomes: Variables like hair color and personal hair growth rates can influence the concentration of drug metabolites in hair.

Note: Commonly known as "hair follicle tests", these tests actually analyze 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.
