Hair Follicle Drug Testing - Knappa, OR

What it is, How it works

Hair analysis is now regarded as an effective approach for detecting drug and alcohol consumption. It offers a prolonged history of substance use by encapsulating biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can indicate alcohol and drug use for roughly three months. Collecting hair is straightforward, challenging to tamper with, and easy to mail.

A hair sample of 1.5 inches, consisting of approximately 200 strands (resembling a #2 pencil), collected nearest to the scalp, yields 100mg of hair, which is optimal for both screening and confirmatory purposes. For tests involving EtG, additional panels, or tests beyond 10 panels, a 150mg sample is suggested. Using a jeweler’s scale for specimen weighing is advised. If scalp hair is not available, an equivalent amount of body hair can be substituted. When head hair is referenced, it specifically pertains to scalp hair. Body hair encompasses all other types (like facial, axillary, etc.).

Process Overview

The drug testing process in a laboratory encompasses Accessioning, Screening, Extraction, and Confirmation as the key phases.

During Accessioning, the sample undergoes initial systemization within the lab. This step ensures proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary additional data input absent from an electronic chain of custody system.

Screening provides an initial assessment for drugs of abuse. While a cost-efficient method to dismiss drug presence in most samples, any positive results from Screening require confirmation for legal acceptance. Samples showing presumptive positives in Screening necessitate secondary confirmation.

In cases of presumptive positives in Screening, additional hair from the primary specimen is utilized for Extraction. At this stage, drugs are extracted at much lower concentrations from hair, compared to other methods (e.g., urine or saliva), making it the most complex methodology to execute.

GC/MS, GC/MS/MS, or LC/MS/MS techniques are used to confirm positive screening outcomes. Presumptive positive samples undergo washing before confirmation if needed. The entire testing procedure from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests may identify drug use for up to 90 days, whereas urine tests offer a shorter window.
• Resistant to manipulation: Cheating on a hair drug test is exceedingly difficult, which enhances result reliability.
• Reveals usage trends: It can show substance use patterns over time, rather than only recent drug intake.

Limitations:

• Incapable of detecting recent intake: It takes about 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests usually cost more than other methods.
• Result variability: Factors such as hair color and personal hair growth variations can impact drug metabolite levels within hair.

Note: Although termed "hair follicle tests," the procedure 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
