Hair Follicle Drug Testing - Colonial Heights, TN

What it is, How it works

Hair analysis is now perceived as an effective method for identifying substance and alcohol consumption. Hair encapsulates a protracted timeline of alcohol and other substance use by embedding biomarkers within the hair strand as it grows. When obtained near the scalp, hair can offer approximately a three-month detection period for alcohol and other substances. Hair is easy to gather, somewhat hard to tamper with, and convenient to transport.

A 1.5-inch segment comprising around 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, the preferred sample amount for analysis and confirmation. For EtG, additional parameters, and/or assays exceeding 10 panels, 150mg of the specimen is advised. It is recommended to measure the specimen using a jeweler’s scale. If head hair is unavailable, an equivalent quantity of body hair might be obtained. Referring to head hair pertains only to scalp hair. Body hair includes all other hair types (facial, underarm, etc.).

Process Overview

The quartet of primary stages in the laboratory analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial integration of a sample into a laboratory’s framework. This encompasses verification that the sample was sealed and transported appropriately, allocation of a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent from an electronic chain of custody system.

Screening performs an initial swift evaluation for substance abuse. While Screening is a cost-efficient strategy to exclude drug usage in most samples, any positive result must be validated for legal admissibility. Samples that show presumptive positivity in Screening necessitate secondary validation.

In the event of a presumptive positive during Screening, additional hair is extracted from the original sample and prepped for Extraction. Here, drugs are withdrawn from hair at a markedly lower concentration compared to other techniques (e.g., urine or oral fluid), thereby presenting hair drug screening as the most challenging technique to execute.

Every positive screening outcome undergoes Confirmation through GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The comprehensive laboratory workflow, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards of accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can discern drug usage for up to 90 days, whereas urine tests have a more limited detection period.
• Difficult to circumvent: It is notably hard to bypass a hair drug evaluation, thereby enhancing result accuracy.
• Supplies chronological data: It offers a track record of drug consumption over time, not merely recent usage.

Limitations:

• Incapable of identifying recent consumption: It requires around 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug evaluations are typically pricier than other drug testing approaches.
• Result variations: Variables such as hair tint and individual disparities in hair growth can influence drug metabolite concentration in hair.

Note: Frequently termed as "hair follicle tests", the test itself examines the hair strand rather than the scalp-embedded hair follicle

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.
