Hair Follicle Drug Testing - Nora, NE

What it is, How it works

Hair follicle analysis is increasingly recognized as an effective means for identifying the consumption of alcohol and illicit substances. Hair fibers capture and preserve biomarkers within the strands as they grow, offering an extensive record of substance use. When sampled close to the scalp, these fibers can reflect substance consumption over a period of up to 90 days. Hair sample collection is straightforward, relatively tamper-resistant, and easy to transport.

A hair sample measuring 1.5 inches and comprising roughly 200 hairs (similar to the thickness of a #2 pencil) nearest to the scalp yields about 100mg, which is considered optimal for screening and confirmatory tests. For EtG assessments, additional evaluations, or panels exceeding 10, a sample of 150mg is advised. It is recommended to measure the sample using a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair is acceptable. The term 'head hair' specifically refers to scalp hair, whereas 'body hair' pertains to other types (like facial, axillary, etc.).

Process Overview

The key phases in processing laboratory drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates when a sample enters the laboratory system. This process verifies the sample is appropriately sealed and shipped, assigns it a unique LAN (Laboratory Accessioning Number), and handles any necessary data that isn't accounted for by an electronic chain of custody system.

Screening provides a preliminary assessment for drug misuse. While economical for excluding drug misuse in many cases, a positive screen requires further Confirmation for validity in legal settings. Samples with initial positive results during Screening must undergo a secondary confirmation.

During the Screening stage, any positive samples necessitate additional hair to be extracted from the initial sample for further preparation. In the Extraction phase, substances are drawn out from the hair at significantly lower concentrations compared to other methods such as urine or saliva testing, explaining why hair-test screening presents the greatest challenges.

Confirmation of positive screening results is performed via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples are cleansed before Confirmation as required. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized according to CAP (College of American Pathologists) Hair standards and accredited to ISO / IEC 17025 criteria.

Hair drug testing benefits:

• Extended detection period: Hair tests can identify substance intake for up to 3 months, unlike urine tests with a limited detection time.
• Improbability to alter: It is highly improbable to deceive a hair test, thus ensuring result accuracy.
• Offers usage history: It presents a timeline of substance use, as opposed to solely recent consumption.

Drawbacks:

• Unable to detect recent consumption: Drugs become traceable in hair after roughly 5 to 7 days.
• Expense: Hair analysis tends to be costlier compared to other testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence metabolite concentrations.

Note: Despite the common terminology "hair follicle tests," these tests evaluate 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.
