Hair Follicle Drug Testing - Friday Harbor, WA

What it is, How it works

Hair testing has become recognized as a robust method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drugs by capturing biomarkers within the fibers of the growing hair strand. When collected near the scalp, hair can provide a detection window of up to about three months for alcohol and drugs. The collection of hair is straightforward, somewhat resistant to tampering, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (approximately the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is the ideal sample for examination and verification. For EtG, additional tests, or panels exceeding 10, it is recommended to collect 150mg of the specimen. Use a jeweler’s scale for weighing the specimen. If scalp hair is unavailable, an equivalent quantity of body hair may be collected. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The primary steps involved in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory’s system. This process includes ensuring the sample was sealed and transported properly, assigning a random LAN (Laboratory Accessioning Number), and entering any additional data not provided by an electronic chain of custody system.

Screening involves a preliminary rapid assessment for drugs of abuse. While Screening is an economical way to dismiss drug use in most samples, a positive screen needs confirmation to be admissible in court. Samples that screen positive presumptively in Screening require further confirmation.

If a sample is presumptively positive during the Screening phase, additional hair is taken from the initial sample for Extraction. In this phase, drugs are extracted from hair at a much lower concentration than in other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are washed before confirmation as necessary. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests, which have a shorter detection window.
• Hard to manipulate: It is very challenging to falsify a hair drug test, making the outcomes more trustworthy.
• Supplies historical data: It can showcase a pattern of drug use over time, not just recent usage.

Limitations:

• Incapable of detecting recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests are typically more costly than other drug testing methods.
• Result variability: Factors such as hair color and individual hair growth variations can impact the concentration of drug metabolites.

Note: Although commonly called "hair follicle tests," the analysis is conducted on the hair strand, not 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.
