Hair Follicle Drug Testing - Gorst, WA

What it is, How it works

Hair evaluations have emerged as an effective resource for identifying alcohol and drug consumption. Hair captures a comprehensive history of alcohol and substance use by embedding biomarkers within the fibers of the developing hair shaft. When harvested near the scalp, hair can offer up to a roughly three-month detection period for alcohol and drugs. Hair is straightforward to collect, relatively challenging to tamper with, and simple to transport.

A 1.5-inch portion of approximately 200 hair strands (about the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for screening and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of the specimen is advised. We suggest using a jeweler's scale to weigh the sample. If scalp hair is not accessible, a comparable quantity of body hair can be gathered. By head hair, we mean specifically scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four principal phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary handling of a sample within a lab’s framework. This stage involves verifying that the sample remained sealed and was dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any additional data required beyond what an electronic chain of custody system supplies.

Screening represents an initial rapid evaluation for drug abuse. Although Screening is a cost-efficient approach to disprove drug usage for the majority of samples, a positive screening necessitates confirmation to be deemed valid in legal settings. Samples that are presumed positive in Screening must undergo a secondary confirmation.

For samples presumed positive during Screening, more hair is extracted from the initial sample and prepped for Extraction. In this phase, substances are pulled from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging technique to conduct.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples initially presumed positive are washed before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug assessments can recognize drug usage for up to 90 days, whereas urine assessments present a narrower detection timeframe.
• Challenging to manipulate: Hair drug tests are notably difficult to manipulate, ensuring more reliable outcomes.
• Offers historical usage data: It provides an account of drug use over a duration, not solely recent usage.

Drawbacks:

• Cannot identify recent intake: It typically takes about 5-7 days for substances to become perceptible in hair.
• Expense: Hair drug assessments generally incur higher costs than alternative drug testing techniques.
• Outcome variability: Elements such as hair hue and personal differences in hair growth can influence the concentration of drug metabolites within hair.

Note: Often labeled as "hair follicle tests," the analysis targets the hair shaft rather than the hair 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.
