Hair Follicle Drug Testing - Vaughan, NC

What it is, How it works

Hair testing is regarded as an effective method for detecting drugs and alcohol use. Hair retains a long-term record of drugs and alcohol by embedding biomarkers within the hair strand fibers as they grow. When hair is obtained near the scalp, it can offer up to a 3-month detection period for these substances. Hair collection is straightforward, challenging to manipulate, and easy to transport.

A 1.5-inch segment comprising roughly 200 hair strands (equivalent to a #2 pencil's thickness) nearest to the scalp yields 100mg of hair, which is the optimal sample amount for both screening and confirmation processes. For EtG, additional tests, and/or tests exceeding 10 panels, a specimen weighing 150mg is suggested. Using a jeweler's scale for weighing the specimen is advisable. If scalp hair isn't accessible, like-amount body hair may be used. When we mention head hair, we specifically mean scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The principal four stages in the laboratory process of handling a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase, involving inputting a sample into a laboratory's system. It consists of ensuring the sample was correctly sealed and delivered, assigning it a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not done by an electronic chain of custody system.

Screening serves as a preliminary swift inspection for substances of abuse. Although Screening is a budget-friendly approach to eliminate drug presence in most samples, a positive outcome must be confirmed to be legitimate in legal situations. All samples that are found likely positive during Screening necessitate an additional confirmation.

If a sample shows likely positivity during the Screening phase, further hair is taken from the preliminary specimen and prepared for Extraction. At this stage, substances are extracted from hair at a considerably lower concentration than in other approaches (e.g., urine or oral fluid), highlighting why hair drug screening is a challenging technique to execute.

Any positive screening outcomes undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All likely positive samples are cleaned prior to confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and adheres to the ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can reveal drug use for a span of 90 days, unlike urine tests which have a more limited detection window.
• Challenging to manipulate: Cheating is extremely challenging with hair drug tests, thus the results are more reliable.
• Delivers historical information: It can showcase a pattern of drug usage across time, not just recent usage.

Limitations:

• Unable to detect recent usage: It usually requires around 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Variability in results: Elements such as hair shade and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Commonly termed as "hair follicle tests", the examination actually analyzes 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.
