Hair Follicle Drug Testing - Chester, IA

What it is, How it works

Hair testing is now recognized as an effective approach for identifying drug and alcohol consumption. Hair retains a prolonged history of alcohol and drugs by capturing biomarkers in the fibers of the developing hair strand. When harvested near the scalp, hair can deliver up to a roughly three-month window for detecting alcohol and other substances. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.

A sample of 1.5 inches comprising approximately 200 hair strands (roughly equivalent to the thickness of a #2 pencil) taken nearest to the scalp yields 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg specimen is advisable. It is suggested to weigh the specimen using a jeweler's scale. If scalp hair is unavailable, a similar quantity of body hair can be collected. References to head hair pertain to scalp hair exclusively. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

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

During Accessioning, a sample is initially processed into the lab's system. This step involves checking that the sample is sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody system.

Screening provides a preliminary quick test for drugs of abuse. Although Screening is a cost-efficient method to rule out drug use in most samples, a positive result necessitates confirmation for court admissibility. Samples presumed positive in Screening require further confirmation.

If a sample tests positive during Screening, additional hair is extracted from the initial specimen and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of performing hair drug screening.

Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All initial positive samples undergo necessary washing before confirmation. The complete laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug usage for up to 90 days, whereas urine tests cover a shorter span.
• Resistance to tampering: It is challenging to manipulate a hair drug test, ensuring more reliable results.
• Provides historical evidence: It can reveal a history of drug use over time, not only recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests generally incur higher costs compared to other methods.
• Result variability: Elements like hair color and individual hair growth differences may influence drug metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests", the actual analysis is conducted on 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.
