Hair Follicle Drug Testing - Adelphi, MD

What it is, How it works

Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by embedding biomarkers within the growing strand's fibers. When collected near the scalp, it offers a detection duration of up to around three months for alcohol and other substances. Its collection is straightforward, challenging to tamper with, and simple to ship.

A sample of 1.5 inches comprising roughly 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp provides 100mg, which is the optimal amount for both screening and confirmation. For tests like EtG, add-ons, or those beyond 10 panels, 150mg is preferred. We advise using a jeweler’s scale for weighing the specimen. In the absence of scalp hair, a similar quantity of body hair is acceptable. By head hair, we mean only scalp hair, while body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The four crucial phases in the lab processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial intake of a sample into a lab’s system, ensuring the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and entering any further data not covered by an electronic chain of custody.

Screening is a preliminary, quick check for drug substances. Though cost-efficient for ruling out drug consumption in most samples, any positive screen requires confirmation for court legitimacy. Presumptive positive findings in Screening demand additional confirmation.

Should a specimen test presumptively positive during Screening, more hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at significantly lower levels than alternative methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of positive screening outcomes uses GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive specimens are cleansed before confirmation as necessary. The entire laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and accreditation pursuant to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair tests can ascertain drug usage for as long as 90 days, unlike urine assessments which have a limited range.
• Tough to falsify: Hair tests are challenging to deceive, thereby enhancing accuracy.
• Offers historical insight: Provides a usage pattern over time, not limited to recent activities.

Limitations:

• Inability to detect recent consumption: Detection in hair takes roughly 5-7 days post-use.
• Expense: Hair tests generally incur higher costs than other testing methodologies.
• Variable results: Elements like hair color and individual growth rates can influence metabolite concentration in hair.

Note: The so-called "hair follicle tests" evaluate the hair strand and 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.
