Hair Follicle Drug Testing - Catalina, AZ

What it is, How it works

Hair assessments are increasingly regarded as an effective means for identifying drug and alcohol consumption. The strands capture biomarkers over time, creating a lengthy timeline of alcohol and substance history. Hair obtained near the scalp can reveal a detection period of around 3 months for both alcohol and drugs. It's straightforward to collect, hard to tamper with, and effortless to transport.

A 1.5-inch section consisting of roughly 200 strands (comparable to a #2 pencil's width) cut nearest to the scalp provides 100mg of hair, which is optimal for analysis and verification. For add-ons like EtG or tests exceeding 10 panels, 150mg is advisable. We advocate using a jeweler's scale for weighing the sample. In instances where scalp hair isn't accessible, a similar quantity of body hair can be gathered. 'Head hair' exclusively refers to scalp hair, whereas 'body hair' encompasses all other types (e.g., facial, axillary).

Process Overview

The comprehensive processing of a drug test result at a laboratory involves four major phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails incorporating a sample into a laboratory's framework. This step involves verifying the sample's proper sealing and shipping, issuing a random LAN (Laboratory Accessioning Number), and completing any missing data entry not handled by an electronic chain of custody system.

Screening is an initial cursory examination for substances. While economic for dismissing drug use in most cases, any positive screen must be confirmed to be court-admissible. Samples that presumptively test positive require subsequent confirmation.

Should a specimen test presumptively positive during Screening, additional hair is taken from the original sample for Extraction. During this phase, drugs are extracted from hair at significantly reduced concentrations compared to other methods (e.g., urine, oral fluid), which makes hair drug screening the most challenging method to execute.

Confirmations for any positive screenings are performed using GC/MS, GC/MS/MS, or LC/MS/MS. Moreover, all presumptive positives undergo washing before confirmation when necessary. Every step in the laboratory procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair assessments can identify drug use for up to 90 days, compared to the shorter detection span of urine tests.
• Hard to falsify: Cheating a hair drug test is notably difficult, thereby enhancing the accuracy of the results.
• Captures historical usage: It reveals a long-term pattern of drug consumption, unlike tests that only show recent use.

Limitations:

• Unable to identify recent usage: It requires around 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests tend to be pricier than alternative drug testing techniques.
• Result variability: Elements such as hair hue and personal differences in hair growth may influence drug metabolite concentrations in hair.

Note: Although commonly known as "hair follicle tests," the test evaluates the hair strand itself, not the follicle beneath the skin.

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.
