Hair Follicle Drug Testing - Mercer, PA

What it is, How it works

Hair testing is now recognized as a robust method for identifying drug and alcohol consumption. By binding biomarkers within the growing hair's fibers, hair offers a lengthy history of alcohol and other drug use. When collected close to the scalp, hair provides a detection window for alcohol and drugs of up to about 3 months. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.

A 1.5-inch sample, approximately 200 hair strands (around the width of a #2 pencil), nearest to the scalp, provides 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg is advised. The specimen should be weighed on a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be collected. "Head hair" specifically refers to scalp hair only, while "body hair" includes all other hair types (facial, axillary, etc.).

Process Overview

The primary steps involved in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial sample processing into a lab's system. This stage involves checking if the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not handled by an electronic chain of custody system.

Screening is an initial speedy check for drugs of abuse. Screening is an economical way to rule out drug use in most samples, but a positive screen requires confirmation for court admissibility. Samples that are presumptively positive during Screening need a confirmatory test.

If a sample is presumptively positive at the Screening phase, additional hair is extracted from the initial sample for preparation in Extraction. In Extraction, drugs are obtained from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug testing is more challenging to perform.

Confirmation of any positive screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS and all samples that appear positive are washed before confirmation as needed. The complete lab process from Accessioning to Confirmation is overseen under both CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can trace drug usage for up to 90 days, in contrast to urine tests, which have a narrower detection timeframe.
• Hard to deceive: Cheating a hair drug test is quite challenging, lending credence to the results.
• Offers historical insights: It delivers a pattern of drug use over time, not merely recent usage.

Limitations:

• Not effective for recent use: It takes approximately 5-7 days for drugs to appear detectable in hair.
• Expense: Hair drug tests are typically more costly than other testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentration in the hair.

Note: While sometimes called "hair follicle tests," the actual analysis is 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
