Hair Follicle Drug Testing - Krakow, WI

What it is, How it works

Hair testing is viewed as a potent method for identifying drug and alcohol consumption. It offers an extensive history of alcohol and drugs by capturing biomarkers within the fibers of the hair strand that grows. When gathered close to the head, hair can offer roughly a 3-month window for detecting alcohol and drugs. Hair collection is straightforward, somewhat hard to tamper with, and easy to transport.

A 1.5-inch sample containing around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the perfect sample amount for screening and confirmation. For EtG, add-ons, and/or tests surpassing 10 panels, a specimen of 150mg is advised. Using a jeweler’s scale for weighing the specimen is recommended. If scalp hair is not obtainable, a similar amount of body hair can be gathered. References to head hair specifically imply scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for processing a drug test outcome consists of four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample into a lab’s system. This step includes ensuring the sample is sealed and shipped correctly, allocating a random LAN (Laboratory Accessioning Number), and executing any additional data entry not facilitated by an electronic chain of custody system.

Screening entails an initial rapid evaluation for drugs of abuse. Although Screening is a cost-efficient method to dismiss drug use in most samples, a positive screen result requires confirmation to be valid in court. Any samples that yield a presumptive positive result during Screening need a subsequent confirmation.

If a sample delivers a presumptive positive result during Screening, additional hair is extracted from the original specimen and readied for Extraction. In this stage, drugs are extracted from hair at substantially lower concentrations than other methodologies like urine or oral fluid, which makes hair drug screening the most challenging methodology.

Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The full lab process from Accessioning to Confirmation aligns with both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can detect drug consumption for as long as 90 days, in comparison to urine tests which have a shorter detection span.
• Challenging to circumvent: Cheating on a hair drug test is exceedingly difficult, enhancing the accuracy of results.
• Provides historical insight: It reveals a pattern of drug usage over a timeframe, rather than solely recent use.

Limitations:

• Inability to identify recent use: It takes approximately 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests tend to be pricier than alternative drug testing techniques.
• Result variations: Elements such as hair color and individual hair growth variability can influence the concentration of drug metabolites in the hair.

Note: The term "hair follicle tests" is often used, but the test actually assesses the hair strand, not the follicle below 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.
