Hair Follicle Drug Testing - Dulles Town Center, VA

What it is, How it works

Hair examinations have been increasingly recognized as an effective resource for identifying drug and alcohol consumption. Hair retains a comprehensive timeline of alcohol and drug use by encasing biomarkers within the fibers of the expanding hair strand. When taken near the scalp, hair can reveal up to an approximate 3-month detection period for alcohol and drugs. Hair is straightforward to collect, somewhat challenging to tamper with, and simple to transport.

A 1.5-inch lock consisting of around 200 hair strands (approximately the size of a #2 pencil) near the scalp provides 100mg of hair, the optimal amount for screening and confirmation. For EtG, additional tests, and/or analyses exceeding 10 panels, 150mg of the sample is suggested. It is advisable to assess the sample weight using a jeweler’s scale. Should scalp hair be inaccessible, a comparable quantity of body hair can be procured. In reference to head hair, only scalp hair is implied. Body hair pertains to all other types of hair (facial, axillary, etc.).

Process Overview

The process of lab testing to determine a drug test outcome involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial entry of a sample into a lab’s system. It encompasses checking that the sample is sealed and conveyed adequately, allocating a random LAN (Laboratory Accessioning Number), and finishing any supplementary data entry not catered by an electronic chain of custody system.

Screening is a rapid initial test for drug presence. Although Screening is an efficient method to negate drug use for most samples, a positive screen must be verified to be valid in a legal setting. Any samples deemed presumptively positive in Screening necessitate an additional confirmation.

If a sample is presumptively positive during the Screening phase, extra hair is retrieved from the initial sample and readied for Extraction. Here, drugs are leached from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging method to execute.

Confirmation of a positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive cases are cleansed before confirmation as needed. The complete laboratory cycle from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accredited by ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection window: Hair drug assays can recognize drug usage for up to 90 days, in contrast to urine tests that have a shorter detection span.
• Tough to deceive: It is quite tough to falsify a hair drug test, ensuring more reliable results.
• Yields historical data: It can outline a drug usage pattern over time, beyond just the recent usage.

Constraints:

• Incapable of identifying recent usage: It takes roughly 5-7 days for drugs to become identifiable in hair.
• Expense: Hair drug analyses are typically more costly than alternative drug testing techniques.
• Outcome variability: Elements such as hair color and personal variances in hair growth can influence drug metabolite concentration within the hair.

Note: Despite the common term "hair follicle test", the analysis itself investigates 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.
