Hair Follicle Drug Testing - Sloan, IA

What it is, How it works

Hair assessments have become recognized as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug use by encapsulating biomarkers within the fibers of the growing hair. When sourced close to the scalp, it can offer a detection span reaching up to three months for substances like alcohol and other drugs. Hair collection is straightforward, moderately challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches, comprised of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is considered the optimal sample size for both screening and confirmation processes. For EtG, add-ons, and/or tests exceeding 10 panels, it is advisable to use 150mg of the sample. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn't accessible, a comparable quantity of body hair can be utilized. When discussing head hair, it specifically pertains to scalp hair alone. Body hair signifies all other types of hair (such as facial, axillary, etc.).

Process Overview

There are four core stages involved in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into a lab's system, including ensuring the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finalizing any further data input not supplied by an electronic chain of custody system.

Screening is a preliminary swift evaluation for substances of abuse. While it is a cost-efficient method to exclude drug presence in most samples, a positive screen requires confirmation to be court-admissible. Any presumptively positive samples in Screening necessitate further confirmation.

If a sample tests positive in the Screening phase, additional hair is extracted from the primary specimen and prepared for Extraction. At this stage, substances are removed from the hair at a much lower concentration compared to other methodologies (such as urine or oral fluid), which makes hair drug screening the most intricate methodology to conduct.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation if needed. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as long as 90 days, in contrast to urine tests that have a shorter span of detection.
• Hard to trick: It's highly challenging to deceive a hair drug test, thus enhancing result accuracy.
• Offers historical insight: It can reveal a trend of drug use over time, not merely recent usage.

Limitations:

• Cannot identify recent consumption: Drugs only become detectable in hair after about 5-7 days.
• Expense: Hair drug tests are generally costlier than other drug testing methods.
• Differences in results: Variables such as hair color and personal variations in hair growth can influence the drug metabolite concentration in hair.

Note: Though often termed as "hair follicle tests", the analysis examines the hair strand itself, not the hair 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.
