Hair Follicle Drug Testing - Nazlini, AZ

What it is, How it works

Regarded as an effective instrument for identifying drug and alcohol consumption, hair testing offers a prolonged history of these substances by capturing biomarkers within the growing hair strand fibers. When sourced near the scalp, hair can reveal up to an approximate 3-month window of detection for alcohol and other drugs. Collection of hair is straightforward, relatively resistant to tampering, and easy to transport.

A sample measuring 1.5 inches with around 200 strands (about the girth of a #2 pencil) close to the scalp secures 100mg of hair, which is the optimal sample quantity for screening and confirmation. For EtG, add-ons, or tests that exceed ten panels, a specimen of 150mg is advised. It is suggested to weigh the specimen using a jeweler’s scale. In the absence of scalp hair, a similar volume of body hair may be used. Here, head hair refers specifically to scalp hair, whereas body hair includes all other types (such as facial or axillary).

Process Overview

The laboratory processing involved in drug testing encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the laboratory's framework. This step includes confirming that the sample was adequately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.

Screening performs an initial swift evaluation for drugs of concern. While Screening is an economical method to exclude drug presence in most samples, a positive outcome must be verified to be court-eligible. Samples tentatively positive from Screening necessitate further confirmation.

For samples preliminarily positive during Screening, more hair is extracted from the primary specimen and readied for Extraction. Here, drugs are isolated from hair at concentrations much lower than alternative methods (such as urine or oral fluid), underscoring the complexity of conducting hair drug screening.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo cleansing before confirmation if needed. The complete lab process from Accessioning through to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation as well as alignment with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug assessments can sense drug usage for up to 90 days, whereas urine tests possess a briefer detection span.
• Hard to subvert: Cheating a hair drug test is challenging, thus boosting result accuracy.
• Chronic usage insights: It reveals usage patterns over time rather than just recent consumption.

Limitations:

• Lacks immediate detection: Drugs become noticeable in hair roughly 5-7 days post-consumption.
• Expense: Hair drug tests typically incur higher costs than other testing methods.
• Variability in outcomes: Elements like hair color and personal hair growth differences can sway drug metabolite levels in hair.

Note: Despite often being termed "hair follicle tests", this test specifically assesses the hair strand, not 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.
