Hair Follicle Drug Testing - Marbury, MD

What it is, How it works

Hair analysis has emerged as an effective resource for identifying drug and alcohol consumption. Hair captures a prolonged record of drugs and alcohol by embedding biomarkers within the fibers of the developing hair strand. When cut near the scalp, hair can reveal up to roughly a 3-month detection period for alcohol and drugs. Hair is straightforward to obtain, relatively hard to tamper with, and simple to transport.

A 1.5-inch segment of about 200 hair strands (akin to the size of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal quantity for analysis and validation. For EtG, supplementary tests, and examinations beyond 10 panels, 150mg of the sample is advisable. We suggest measuring the sample on a jeweler's scale. If scalp hair is absent, a comparable amount of body hair can be gathered. Pertaining to head hair, this exclusively means scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four critical stages in the lab handling of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial handling of a sample into a lab's database. This process includes confirming that the sample was appropriately sealed and dispatched, designating a random LAN (Laboratory Accessioning Number), and performing any extra data input not supplied by an electronic chain of custody system.

Screening entails an initial rapid assessment for drugs of misuse. While Screening is a cost-efficient approach to eliminate drug use in most samples, a positive result must be confirmed for court admissibility. Any samples showing presumptive positivity in Screening necessitate a supplementary confirmation.

If a sample is presumptively positive during the Screening phase, additional hair is extracted from the original sample and set for Extraction. At this stage, drugs are extracted from hair at a much lower concentration than with other techniques (e.g., urine or oral fluid), which is why hair drug screening is the most challenging technique to execute.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing prior to confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a more brief detection window.
• Challenge to manipulate: Cheating a hair drug test is highly challenging, ensuring more accurate results.
• Offers historical insight: It reveals a pattern of drug use over time, not merely recent consumption.

Drawbacks:

• Cannot identify recent use: It takes around 5-7 days for drugs to become identifiable in hair.
• Expense: Hair drug tests typically cost more than other drug testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can impact drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis examines 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.
