Hair Follicle Drug Testing - Coward, SC

What it is, How it works

Hair analysis is now acknowledged as a vital method for identifying drug and alcohol consumption. Hair traps biomarkers within the fibers of the developing hair strand, offering an extensive timeline of alcohol and drug use. When taken near the scalp, hair allows for up to a roughly three-month detection period for drugs and alcohol. Collecting hair is straightforward, moderately resistant to tampering, and simple to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp, will produce 100mg of hair, which is the optimal sample size for testing and verification. For EtG extensions, and/or testing exceeding 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale to weigh the sample. Should scalp hair be inaccessible, a comparable quantity of body hair may be gathered. References to head hair pertain strictly to scalp hair, while body hair includes all other types (e.g., facial, axillary).

Process Overview

The key stages in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves entering a sample into a lab’s system straightforwardly. This entails checking that the sample was sealed and sent correctly, allocating a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry not included by an electronic custody record.

Screening comprises a primary rapid inspection for drugs. While Screening is a budget-friendly means to exclude drug use on most samples, a positive screen must be corroborated to be valid in judicial settings. Any samples showing a presumptive positive outcome in Screening necessitate further confirmation.

Should a sample show a presumptive positive in the Screening phase, additional hair is extracted from the initial sample for Extraction. Here, drugs are withdrawn from hair at a significantly lesser concentration than seen with other methods (e.g., urine or oral fluid), which is why hair drug testing is the most intricate method to undertake.

Confirmation for any positive screen result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation as needed. The complete lab process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair criteria and the approval to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection frame: Hair drug examinations can recognize drug usage for as long as 90 days, unlike urine tests which have a shorter span.
• Hard to tamper with: Cheating a hair drug test is highly challenging, increasing the reliability of the outcomes.
• Offers historical insight: It can reveal a timeline of drug use over time, not just recent consumption.

Limitations:

• Inability to reveal recent use: It takes around 5-7 days for drugs to manifest in hair.
• Expense: Hair drug assessments typically incur higher costs than other drug screening techniques.
• Result variability: Elements like hair color and individual hair growth differences can influence the concentration of drug metabolites in the hair.

Note: Although commonly referred to as "hair follicle tests", the examination focuses on 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.
