Hair Follicle Drug Testing - East Chain, MN

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol use. Hair retains a long-term history of these substances by embedding biomarkers within the fibers of the hair as it grows. When a sample is taken close to the scalp, hair can provide a detection period of up to around three months for alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and easy to transport.

A hair sample of 1.5 inches comprising roughly 200 strands (about the width of a #2 pencil) nearest to the scalp will yield 100mg, which is the optimal amount for both screening and verification. For EtG, add-ons, or testing beyond 10 panels, it is advised to collect 150mg of hair. We suggest measuring the sample with a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair can be collected. When we mention head hair, we are exclusively referring to scalp hair. Body hair encompasses all other types, such as facial, axillary, etc.

Process Summary

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into a lab's system. This involves confirming that the specimen was correctly sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and completing any extra data recording absent from an electronic chain of custody system.

Screening entails an initial rapid assessment for substance abuse. While Screening is a cost-effective approach to exclude drug use in most samples, a positive result requires confirmation for legal admissibility. Samples that are presumptively positive in Screening must undergo secondary confirmation.

If a sample returns a presumptive positive result at the Screening stage, further hair is extracted from the original sample for Extraction. In this phase, substances are isolated from hair at concentrations much lower than those in other methods (e.g., urine or saliva), which is why hair drug screening is one of the most challenging methodologies.

Positive screening results are confirmed using GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples with presumptive positive results are washed before confirmation if necessary. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug use for up to 90 days, in contrast to urine tests which have a shorter detection period.
• Hard to manipulate: Cheating on a hair drug test is more challenging, leading to more accurate outcomes.
• Historical insights: It provides a timeline of drug use over time, not just recent consumption.

Drawbacks:

• No recent use detection: It takes about 5-7 days for drugs to become evident in hair.
• Expense: Hair drug tests are typically pricier than alternative drug testing methods.
• Result variability: Elements like hair pigmentation and individual differences in growth can influence drug metabolite concentrations in the hair.

Note: Although commonly called "hair follicle tests", the test 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.
