Hair Follicle Drug Testing - Beaverton, OR

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair fibers capture biomarkers which record a history of alcohol and other drugs use over time. When collected near the scalp, hair offers a detection window of up to three months for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and convenient for shipping.

A sample length of 1.5 inches, consisting of approximately 200 hair strands (similar to the thickness of a #2 pencil), provides around 100mg of hair, which is optimal for screening and verification. For tests such as EtG, additional tests, or tests with over 10 panels, it is advisable to collect 150mg of the specimen. The specimen should be weighed using a jeweler’s scale. If scalp hair is unobtainable, an equivalent amount of body hair may be used. It is important to note that when mentioning head hair, only scalp hair is implied. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

There are four crucial stages involved in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the process of incorporating a sample into the lab’s setup. This step includes confirming the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any other data entry requirements not handled by an electronic chain of custody system.

Screening provides a preliminary assessment for substances of abuse. Although Screening is cost-effective for ruling out drug use for most samples, any positive findings require confirmation to be court-acceptable. Presumptive positives during Screening necessitate additional confirmation steps.

For samples testing presumptively positive in the Screening phase, additional hair from the sample is used for the Extraction phase. In this phase, drug substances are extracted from hair at concentrations lower than other methods (e.g., urine or oral fluid), showcasing the complexity of hair drug screening procedures.

Verification of any positive Screening results is done using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positives undergo washing as per requirement. The entire lab process, from Accessioning to Confirmation, is meticulously reviewed under the CAP (College of American Pathologists) Hair designation and aligned with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, in comparison to urine tests that have a limited detection period.
• High accuracy: Cheating a hair drug test is quite challenging, making the outcomes more reliable.
• Drug use timeline: It provides insights into drug usage patterns over time, not merely recent consumption.

Limitations:

• Can't identify recent use: There is a 5-7 day delay before drugs become traceable in hair.
• Expense: Generally, hair drug tests cost more than other testing alternatives.
• Result variance: Elements like hair color and individual hair growth differences can influence drug metabolite concentration in hair samples.

Note: Referred to as "hair follicle tests", the analysis focuses on the hair strand itself, 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.
