Hair Follicle Drug Testing - Niota, TN

What it is, How it works

Hair testing is recognized as an effective means for detecting drug and alcohol consumption. Hair captures a long-term record of substance use by embedding biomarkers within the fibers of the growing hair strand. When collected near the scalp, hair can offer a detection period of up to approximately three months for alcohol and drugs. Hair is straightforward to gather, relatively challenging to tamper with, and easy to transport.

A sample length of 1.5 inches consisting of about 200 hair strands (roughly the width of a #2 pencil) nearest to the scalp can provide 100mg of hair, which is the optimal amount for both screening and verifying. For EtG, additional tests, and/or those exceeding 10 panels, a 150mg sample is recommended. Using a jeweler’s scale to weigh the sample is advised. If scalp hair isn't feasible, a similar quantity of body hair can be used. When mentioning head hair, it refers exclusively to scalp hair. Body hair pertains to all other types (facial, axillary, etc.).

Process Overview

Laboratory processing of a drug testing result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a sample into a lab’s system. This step ensures the sample was properly sealed and shipped, allocates a random LAN (Laboratory Accessioning Number), and inputs any extra data not covered by an electronic chain of custody system.

Screening entails a quick preliminary check for drug abuse. Although Screening is a cost-effective means of discounting drug usage for most samples, any positive outcome must be confirmed for legal acceptability. Samples with presumptive positive results during Screening require a secondary confirmation.

For samples testing presumptively positive at the Screening phase, additional hair is retrieved from the initial sample and prepared for Extraction. At this stage, drugs are extracted at significantly lower concentrations compared to other methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.

Any positive screen result is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as necessary. The entire lab process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug tests can show drug use for up to 90 days, unlike urine tests which offer a shorter time frame.
• Hard to falsify: A hair drug test is very hard to cheat, rendering the results more reliable.
• Reveals historical patterns: It provides insights into drug usage patterns over time, not just recent activity.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variability: Factors like hair color and personal hair growth differences can impact drug metabolite levels in hair.

Note: Commonly dubbed as "hair follicle tests," this test examines the hair strand itself 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.
