Hair Follicle Drug Testing - Sheldon, VT

What it is, How it works

Hair analysis is regarded as an effective means for detecting drug and alcohol consumption. It provides an extended record of alcohol and drug exposure by embedding biomarkers in the fibers of the developing hair strand. When taken near the scalp, hair can offer up to a roughly 3-month detection span for alcohol and drugs. Hair collection is easy to perform, somewhat hard to tamper with, and convenient for shipping.

An ideal sample consists of a 1.5-inch segment of about 200 hair strands (similar in size to a #2 pencil) closest to the scalp, yielding 100mg of hair necessary for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the specimen is advised. Use a jeweler’s scale for weighing the hair sample. Should scalp hair not be available, an equivalent amount of body hair is collectable. "Head hair" specifically denotes scalp hair. Body hair includes all other types (e.g., facial, axillary).

Process Overview

The four principal phases in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample is initially processed into the laboratory system. This step involves confirming the sample was appropriately sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and performing any added data entry not supported by an electronic chain of custody system.

Screening serves as a rapid drug abuse check. The cost-effective Screening method helps exclude drug use in most samples, although court admissibility necessitates confirmation of any positive screens. All samples that test presumptively positive during Screening must undergo secondary confirmation.

Should a sample test presumptively positive during Screening, more hair is extracted from the original specimen for Extraction. In this stage, drugs are retrieved from hair at significantly lower concentrations compared to other methodologies (like urine or oral fluid), making hair drug testing the most challenging methodology.

Confirmation of any positive result from Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive are cleansed before confirmation as needed. The process from Accessioning to Confirmation is comprehensively reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, whereas urine tests cover a shorter duration.
• Hard to tamper with: Cheating a hair drug test is notably challenging, rendering the outcomes more reliable.
• Shows usage trends: It illustrates drug use patterns over time, not just recent consumption.

Limitations:

• Unable to detect recent usage: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Higher cost: Hair drug tests typically incur greater expense compared to other testing methods.
• Variability in results: Elements like hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Despite being commonly termed as "hair follicle tests", the analysis examines the hair strand rather than the scalp’s 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.
