Hair Follicle Drug Testing - Waves, NC

What it is, How it works

The analysis of hair has grown to be regarded as an effective means for the identification of drug and alcohol consumption. Hair can capture a long-term record of alcohol and drugs by sealing biomarkers in the strands of the hair as it grows. When retrieved near the scalp, hair can deliver roughly a three-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and uncomplicated to transport.

A 1.5-inch portion of about 200 strands of hair (comparable to the size of a #2 pencil) nearest the scalp will yield 100mg of hair, the optimal sample size for both screening and verification. For EtG, supplemental tests, and/or tests beyond 10 panels, 150mg of the sample is advisable. We suggest weighing the sample with a jeweler’s scale. If scalp hair isn't an option, an equivalent amount of body hair may be utilized. When indicating head hair, we refer specifically to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The procedure of laboratory processing of a drug test result comprises four central stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves preliminarily integrating the sample into the laboratory’s framework. This means ensuring the sample was sealed and shipped correctly, generating a random LAN (Laboratory Accessioning Number), and completing any missing data not provided by an electronic chain of custody system.

Screening involves conducting an initial rapid assessment for drugs of abuse. While Screening is an economical approach to eliminate up to 90% of samples testing negative for drugs, any positive indication necessitates confirmation for legal admissibility. Samples that are presumptively positive in Screening require secondary confirmation.

If a sample evidences a presumptive positive in the Screening phase, additional hair is pulled from the initial sample and prepared for Extraction. This phase involves extracting drugs from hair at much lower concentrations than other testing methods (e.g., urine or oral fluid), making hair drug screening among the most challenging methods to conduct.

Confirmation of any positive screening outcomes is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect drug use for up to 90 days, whereas urine tests have a shorter detection span.
• Hard to deceive: It is challenging to manipulate a hair drug test, thereby ensuring accuracy.
• Provides usage patterns: It can illustrate a history of drug consumption, not just recent use.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests generally incur higher costs than alternative methods.
• Results variability: Hair color and individual hair growth can influence drug metabolite concentrations.

Note: Though often termed "hair follicle tests", the analysis focuses on the hair strand, not the scalp follicle.

Why Hair Follicle Testing Beats Urine Testing

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.
