Hair Follicle Drug Testing - Forest Grove, OR

What it is, How it works

Hair evaluation is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within its strands. Obtaining samples close to the scalp enables up to about a three-month timeline for detecting alcohol and drugs. This method is straightforward to collect, relatively hard to tamper with, and convenient for transportation.

A sample being 1.5 inches long consisting of approximately 200 hair strands (roughly the thickness of a #2 pencil) from near the scalp yields 100mg, ideal for screening and confirmation. For EtG, additional tests, or those exceeding ten panels, a 150mg sample is advocated. We recommend using a jeweler's scale to weigh the specimen. If scalp hair is not available, an equivalent volume of body hair may be used. The term head hair refers exclusively to scalp hair, whereas body hair encompasses other varieties (facial, axillary, etc.).

Process Summary

The primary stages in laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial integration of a sample into a lab's framework, which covers verifying proper sealing and shipping, allocating a unique LAN (Laboratory Accessioning Number), and executing any data entry absent from an electronic chain of custody.

Screening offers an immediate assessment for abusive substances. Though it is cost-efficient for ruling out drug usage on the majority of samples, a positive screen must be verified to stand up in legal proceedings. Samples that test presumptive positive in Screening necessitate follow-up confirmation.

For samples identified as presumptively positive during Screening, further hair is extracted from the original sample for the Extraction process. Here, drug compounds are extracted from the hair at significantly lower concentrations compared to methods like urine or oral fluid, highlighting the complexity of hair drug testing.

Confirmation of positive Screening results employs techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before Confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is monitored under both CAP (College of American Pathologists) hair standards and certified under ISO/IEC 17025 criteria.

Pros of hair drug testing:

• Extended detection period: Hair drug tests track drug use up to 90 days, unlike urine tests which have limited detection duration.
• Challenging to manipulate: Hair drug tests are hard to deceive, leading to more reliable results.
• Tracks historical consumption: Offers a record of substance use across time, beyond just recent events.

Constraints:

• Unsuitable for recent use detection: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests tend to incur higher costs compared to alternative approaches.
• Variability in outcomes: Factors such as hair pigmentation and personal hair growth can influence drug metabolite levels in hair.

Note: Although occasionally termed as "hair follicle tests", this examination analyzes the hair strand itself, 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.
