Hair Follicle Drug Testing - Blair, NE

What it is, How it works

Hair testing has become recognized as an efficient method for detecting drug and alcohol consumption. Hair captures a comprehensive history of alcohol and drug exposure by embedding biomarkers within the fibers of the growing strand. When taken near the scalp, hair offers a detection window of up to three months for both alcohol and drugs. It is straightforward to gather, challenging to tamper with, and simple to transport.

A 1.5-inch piece consisting of approximately 200 strands of hair (comparable to the girth of a #2 pencil) nearest to the scalp yields 100mg, which is the preferred quantity for both screening and validation. For EtG, additional tests, and/or those exceeding 10 panels, a 150mg sample is suggested. Using a jeweler’s scale for weighing the specimen is advised. If scalp hair cannot be obtained, a similar amount of body hair may be used. Note that when we mention head hair, we specifically mean scalp hair. Body hair encompasses all other types, such as facial and axillary hair.

Process Overview

The laboratory workflow for generating a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab's system. This step verifies the proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any manual data entry omitted by an electronic chain of custody.

Screening serves as an initial, rapid assessment for substance abuse. While this step is a cost-efficient means to exclude drug use in most samples, a positive result necessitates confirmation for legal substantiation. Thus, any screenings showing potential positive results must undergo a confirmatory test.

When a Screening shows potential positivity, additional hair is extracted from the original sample for further preparation in the Extraction phase. During this step, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), illustrating why hair drug analysis presents one of the greatest technical challenges.

Positive screening outcomes are verified via GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are thoroughly cleaned before confirmation as necessary. The entire sequence from Accessioning to Confirmation is scrutinized in accordance with both the CAP (College of American Pathologists) Hair category and ISO / IEC 17025 accreditation guidelines.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can recognize drug use for as long as 90 days, unlike urine assessments that offer a shorter detection span.
• Resistant to falsification: Manipulating results on a hair drug test proves extremely challenging, enhancing reliability of results.
• Chronological usage patterns: Offers insights into drug consumption habits over time, beyond just recent usage.

Limitations:

• Incapable of detecting recent intake: It generally takes 5-7 days post-consumption for drugs to become traceable in hair.
• High cost: Hair drug assessments typically incur greater expenses than alternate testing approaches.
• Variation in outcomes: Elements like hair color and personal differences in hair growth may influence metabolite concentrations within the hair.

Note: Although often called "hair follicle tests," this analysis actually examines the hair shaft, 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.
