Hair Follicle Drug Testing - Bedford Park, IL

What it is, How it works

The assessment of hair samples is recognized as a substantial approach for identifying substance and alcohol consumption. Hair maintains a prolonged record of alcohol and drugs by encapsulating biomarkers in the strands of the developing hair. When sampled near the scalp, hair can offer nearly a 3-month detection window for alcohol and drugs. Hair is straightforward to gather, somewhat resistant to tampering, and simple to transport.

A segment measuring 1.5 inches of approximately 200 strands (comparable to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal quantity for both screening and verification. For EtG, enhancements, or evaluations exceeding 10 panels, a sample of 150mg is advisable. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not obtainable, an equivalent amount of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Summary

The main steps in the laboratory processing of a drug test outcome consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary processing of a sample into a lab's system. This involves confirming the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input not supplied by an electronic chain of custody system.

Screening comprises a preliminary rapid assessment for drug abuse. While Screening serves as a cost-efficient strategy to dismiss drug use for most samples, a positive result requires confirmation to be valid in legal settings. Samples that are initially positive in Screening necessitate further verification.

Should a specimen test positive in the Screening stage, additional hair is extracted from the original sample for preparation in the Extraction step. Here, drugs are removed from hair at a lower concentration than other methodologies (e.g., urine or oral fluid), which is why hair drug testing is considered more complex to perform.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that initially test positive are cleansed before confirmation if needed. The entire lab process from Accessioning through Confirmation is audited under both the CAP (College of American Pathologists) Hair criteria and compliance with ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests with a shorter detection span.
• Hard to manipulate: Hair drug tests are hard to falsify, ensuring more precise results.
• Offers historical insights: It provides a record of drug use spanning a certain timeframe, rather than just recent activities.

Limitations:

• Inability to identify recent use: It takes roughly 5-7 days for drugs to become noticeable in hair.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Outcome variability: Aspects like hair shade and personal hair growth variations can influence drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests", the analysis is conducted on the hair strand, not the follicle under 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.
