Hair Follicle Drug Testing - Plymouth Meeting, PA

What it is, How it works

Hair testing is increasingly regarded as a robust mechanism for identifying drug and alcohol use. The hair acts as a historical repository for alcohol and drug consumption by capturing biomarkers within the growing hair shaft. When taken near the scalp, hair can offer a detection window for up to roughly 3 months for alcohol and drugs. Collection of hair is straightforward, relatively resistant to tampering, and convenient for transport.

A 1.5-inch segment consisting of around 200 hair strands (closely matching the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is suggested. We advocate measuring the specimen using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be gathered. 'Head hair' pertains to scalp hair exclusively, whereas 'body hair' encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The four principal phases in the laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial incorporation of a sample into a lab’s system. This step includes checking that the sample has been properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from the electronic chain of custody system.

Screening consists of a swift preliminary analysis for drugs of abuse. While it is a cost-efficient method to eliminate drug use in most samples, a positive result from Screening needs confirmation for judicial acceptability. Any samples presumed positive in Screening must undergo a secondary confirmation.

If a sample is presumed positive during the Screening stage, additional hair is taken from the original specimen and readied for Extraction. In this phase, drugs are drawn from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive Screening result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive result undergo washing before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests may identify drug use for up to 90 days, compared to the shorter detection period of urine tests.
• Resistance to tampering: Hair drug tests are notably difficult to tamper with, enhancing result reliability.
• Historical data provision: They offer a usage pattern over time rather than recent usage alone.

Limitations:

• Recent usage undetectable: There is a lag of about 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests are typically costlier than other drug testing procedures.
• Result variability: Factors such as hair color and individual hair growth variations can influence drug metabolite concentrations in hair.

Note: Often called "hair follicle tests", the focus is on analyzing the hair strand itself rather than the hair follicle embedded in 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.
