Hair Follicle Drug Testing - Chignik, AK

What it is, How it works

Hair analysis is now recognized as an effective approach for identifying drug and alcohol consumption. The fibers of hair strands, as they grow, encapsulate biomarkers that provide an extended timeline of these substances. Hair samples taken near the scalp can unveil usage spanning roughly three months. This method of collection is straightforward, moderately resistant to tampering, and simple to transport.

A sample measuring 1.5 inches with around 200 hair strands (approximately the thickness of a #2 pencil) from the scalp offers 100mg of hair, which is the optimum quantity for initial screening and confirmation tests. For assessments such as EtG, add-ons, or tests exceeding 10 panels, 150mg is advised. It's advisable to measure the sample weight using a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair may be collected. When mentioning head hair, it exclusively refers to scalp hair, whereas body hair encompasses other types (facial, axillary, etc.).

Process Overview

The drug test evaluation within a lab consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails integrating a specimen into the lab's framework. This phase confirms proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data not already present through an electronic chain of custody system.

Screening provides an initial shallow test for drugs of abuse. Although Screening offers a budget-friendly method for eliminating drug use in numerous cases, any positive outcome requires verification for legal admissibility. Samples that turn out presumptively positive during Screening necessitate further Confirmation.

If Screening results are presumptively positive, additional hair is taken from the original sample for Extraction. Here, drug compounds are separated from the hair at much lower concentrations than those used in other techniques (such as urine or saliva), making hair drug testing the most challenging method to execute.

Confirming a positive test outcome is performed through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo a necessary wash before Confirmation. The entire examination from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timespan: Hair drug testing can reveal drug use up to 90 days, which is longer than the detection period for urine tests.
• Hard to manipulate: Manipulation and cheating are challenging with hair drug tests, leading to more reliable results.
• Chronological usage record: It outlines the pattern of drug usage over an extended timeline instead of just recent consumption.

Limitations:

• Cannot identify recent drug usage: Detecting drugs in hair takes roughly 5-7 days after use.
• Expense: Compared to other testing methods, hair drug tests generally incur higher costs.
• Inconsistent results: Variables like hair color and individual hair growth rates can influence drug metabolite concentration in the hair.

Note: Though often termed "hair follicle tests", the evaluation examines the hair strand rather than 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.
