Hair Follicle Drug Testing - Fithian, IL

What it is, How it works

Hair analysis is now recognized as an effective method to detect substance and alcohol usage. By embedding biomarkers within the growing hair fibers, hair can reveal long-term drug and alcohol history. When taken from near the scalp, hair offers an approximate 3-month detection period for substances. Collection is simple, tampering is challenging, and shipping is straightforward.

A 1.5-inch segment of around 200 hair strands (similar to the width of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal quantity for screening and verification. For EtG, additional tests, or panels exceeding 10, 150mg of the sample is suggested. It's advisable to use a jeweler's scale for weighing the sample. If scalp hair is not present, a comparable quantity of body hair can be used. When referring to head hair, this is specific to scalp hair only. Body hair encompasses all other types of hair (like facial, axillary, etc.).

Process Overview

The four primary steps in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial processing and integration of a sample into the laboratory's framework. This process ensures the sample was securely sealed and properly shipped, generates a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent in an electronic chain of custody protocol.

Screening is an initial rapid evaluation for drugs of abuse. Although Screening is a cost-efficient method to eliminate drug use in most samples, a positive screen requires confirmation to be valid in a legal setting. Samples that are tentatively positive in Screening mandate a secondary confirmation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are isolated from hair at a substantially lower concentration than in alternative methods (e.g., urine or oral fluid), making hair drug analysis the most intricate to execute.

Confirmation of any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample is rinsed before confirmation as warranted. The complete lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can pinpoint drug use for up to 90 days, unlike urine tests which have a shorter timeframe.
• Hard to manipulate: Hair drug tests are exceedingly difficult to tamper with, ensuring more reliable outcomes.
• Shows historical patterns: It can illustrate a timeline of drug use, not just immediate consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests generally incur higher costs than other testing approaches.
• Result variability: Factors such as hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Though often named "hair follicle tests", the assessment actually examines the hair strand, 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.
