Hair Follicle Drug Testing - Loretto, MN

What it is, How it works

Hair examinations are widely acknowledged as an effective method for identifying drug and alcohol consumption. Hair strands encapsulate biomarkers within their fibers, offering a long-term record of substance use. When procured near the scalp, hair can provide an approximate detection span of three months for substances. It is straightforward to gather, challenging to tamper with, and convenient to transport.

A strand sample of 1.5 inches and roughly 200 hairs (comparable to a #2 pencil in size) near the scalp will produce 100mg of hair, which is perfect for both screening and verification. For EtG, additional tests, or testing beyond 10 panels, 150mg is advised. Utilization of a jeweler’s scale for specimen weighing is recommended. In case scalp hair is lacking, an equal collection of body hair is acceptable. When we mention head hair, we mean only scalp hair. Body hair includes all other types like facial or axillary hair.

Process Overview

The laboratory procedure to process a drug test outcome comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the introductory step where a sample is logged into a lab's system. This step verifies the sample's sealing and shipping appropriateness, assigns a random Laboratory Accessioning Number (LAN), and fills in additional data not covered by an electronic chain of custody system.

Screening is an expedited check for drug misuse. Despite being cost-efficient for ruling out drug use in most cases, a positive screen has to be verified to stand in legal contexts. Any samples suspected as positive in Screening necessitate secondary affirmation.

For samples indicating a presumptive positive during Screening, further hair is extracted from the original specimen for Extraction. This procedure extracts drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is the most challenging approach.

Confirmation for any positive screen is executed through GC/MS, GC/MS/MS, or LC/MS/MS methods. All preliminary positive samples undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation is overseen under the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection duration: Hair drug examinations can reveal substance use spanning up to 90 days, unlike urine examinations that detect drug usage over a shorter span.
• Hard to falsify: Cheating on a hair drug examination is nearly impossible, enhancing result accuracy.
• Shows historical substance use: It depicts substance use patterns over time instead of just recent usage.

Limitations:

• Cannot identify recent usage: Drugs become detectable in hair after about 5-7 days.
• Higher costs: Hair drug examinations are typically more costly than other testing methods.
• Results may vary: Aspects like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
