Hair Follicle Drug Testing - Clayton, NC

What it is, How it works

Hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair captures a comprehensive history of substances by retaining biomarkers within the strands as they grow. When gathered from near the scalp, hair can reflect substance use over an approximate three-month period. Hair collection is straightforward, resistant to tampering, and can be easily transported.

A 1.5-inch segment comprising roughly 200 hair strands (around the thickness of a #2 pencil) cut close to the scalp yields 100mg, which is the preferred sample size for both screening and validation. For EtG tests and panels exceeding 10, a 150mg sample is advisable. It's beneficial to measure the sample weight using a jeweler’s scale. If scalp hair is lacking, an equivalent volume of body hair may be utilized. When mentioning head hair, it specifically pertains to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The core stages in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage where a sample is integrated into the lab’s system. This step ensures the sample was sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input not covered by an electronic chain of custody system.

Screening provides an initial rapid assessment for substances of abuse. Although Screening is an economical method to exclude drug use in most samples, a positive result must be corroborated to be legally valid. Positive Screening samples necessitate further confirmation.

When a sample tests positive during Screening, additional hair from the initial batch is prepared for Extraction. In this process, drugs are extracted from hair at significantly lower concentrations than alternative methods (like urine or oral fluids), highlighting the complexity of conducting hair drug screening.

Confirmation of any positive Screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all positive samples undergo washing as required. The comprehensive lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, while urine tests offer a shorter detection timeframe.
• Hard to bypass: Manipulating a hair drug test is extremely difficult, ensuring more reliable results.
• Shows historical usage: It charts drug use trends over time, not merely recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs become traceable in hair roughly 5-7 days post-use.
• Expense: Hair drug tests tend to be pricier than alternative testing methods.
• Result variability: Factors like hair color and personal hair growth variations can influence the drug metabolite levels in hair.

Note: Commonly called "hair follicle tests", the analysis pertains to the hair strand rather than 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.
