Hair Follicle Drug Testing - Weleetka, OK

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying alcohol and drug consumption. Hair records a timeline of substance use by capturing biomarkers within the fibers of its growing strand. When taken near the scalp, hair can offer a detection period of up to about 90 days for alcohol and other substances. The collection of hair is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch segment of around 200 strands of hair (roughly the size of a #2 pencil) closest to the scalp provides 100mg, which is the optimal amount for testing and verification. For EtG, additional screenings, and tests surpassing 10 panels, 150mg is suggested. Using a jeweler’s scale to measure the sample is advised. If scalp hair is unavailable, an equivalent amount of body hair may be utilized. By head hair, we refer specifically to scalp hair. Body hair includes any other varieties (facial, axillary, etc.).

Process Overview

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

Accessioning is the preliminary handling of a sample into a lab’s framework. It involves checking that the sample was sealed and sent correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody system.

Screening entails an initial rapid verification for drugs of misuse. Although Screening is an economical method to exclude drug usage for the majority of specimens, a positive screen requires confirmation to be valid in a legal context. Any specimens presumed positive in Screening necessitate a subsequent confirmation.

If a sample is assumed positive during the Screening phase, more hair is extracted from the original specimen and readied for Extraction. At this point, substances are withdrawn from hair at a significantly lower level than in other techniques (e.g., urine or oral fluid), making hair drug monitoring the most intricate methodology to execute.

Confirmation of any positive screening finding is performed through GC/MS, GC/MS/MS or LC/MS/MS. All assumed positive specimens are cleaned before confirmation as required. The entire lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug evaluations can identify drug use for up to 90 days, contrasting with urine tests that have a briefer detection period.
• Hard to deceive: It is notably challenging to falsify a hair drug test, hence the findings are more reliable.
• Yields historical data: It can illustrate a pattern of drug consumption over time, rather than merely recent use.

Limitations:

• Cannot identify recent usage: Approximately 5-7 days are needed before drugs become detectable in hair.
• Expense: Hair drug tests usually exceed the cost of other drug testing strategies.
• Result variations: Elements such as hair coloration and individual differences in hair growth can influence the drug metabolite concentration within the hair.

Note: Though commonly dubbed "hair follicle tests", the procedure examines 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.
