Hair Follicle Drug Testing - Keys, OK

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. Hair retains a long-term record of alcohol and other substances by embedding biomarkers within the fibers as the hair grows. When collected near the scalp, hair can offer a detection period of up to about three months for alcohol and other substances. Hair collection is straightforward, relatively hard to alter, and simple to transport.

A 1.5-inch segment comprising approximately 200 hairs (around the thickness of a #2 pencil) closest to the scalp provides 100mg, which is the ideal quantity for analysis and confirmation. For EtG, additional tests, and/or screenings exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler's scale to weigh the sample. If scalp hair is not available, an equivalent amount of body hair can be gathered. When mentioning head hair, we are specifically referring to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The four key phases in processing a drug test specimen in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial integration of a sample into a laboratory’s database. This involves checking that the sample was appropriately sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data input absent from the electronic chain of custody system.

Screening includes an initial rapid test for drug abuse. While Screening is a cost-efficient approach to exclude drug use in most samples, a positive screen requires confirmation for court admissibility. Samples presumptively positive in Screening must undergo secondary confirmation.

If a sample tests presumptively positive during Screening, additional hair is taken from the original sample to prepare for Extraction. In this phase, drugs are extracted from hair using a concentration lower than other methods (like urine or oral fluid), making hair drug screening the most intricate methodology to execute.

Confirmation of any positive screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptively positive samples are cleansed prior to confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a shorter detection timeframe.
• Hard to compromise: It is very challenging to manipulate a hair drug test, leading to more precise results.
• Reveals historical data: It can unveil a pattern of drug use over an extended period, not solely recent use.

Limitations:

• Cannot detect recent usage: It takes around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests usually cost more compared to alternative drug testing techniques.
• Result variations: Elements like hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Though frequently termed "hair follicle tests", the analysis itself examines the hair strand and 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.
