Hair Follicle Drug Testing - Point Roberts, WA

What it is, How it works

Hair testing is increasingly recognized as an effective means for detecting drug and alcohol use. Hair strands capture a long-term history of substances by incorporating biomarkers into their growing fibers. When collected near the scalp, hair samples can offer a detection period of up to roughly three months for drugs and alcohol. Hair collection is straightforward, not easily altered, and can be conveniently shipped.

A sample of 1.5 inches of approximately 200 hair strands (equivalent to the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal sample size for both screening and confirmation. For EtG tests, additional panels, or tests exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to measure the specimen's weight. In situations where scalp hair is not available, an equivalent quantity of body hair is an alternative. When we mention head hair, it specifically refers to scalp hair. Body hair includes other hair types (such as facial or axillary hair).

Process Overview

The laboratory procedure for processing a drug test result consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a sample into a lab’s system. This step verifies if the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any ancillary data entry not covered by an electronic chain of custody system.

Screening entails an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient approach to eliminate drug usage in most samples, a positive screening result must be validated to be legally permissible. Samples that return a presumptive positive from Screening require a subsequent confirmation.

Should a sample test presumptive positive during the Screening phase, additional hair is extracted from the original specimen for the Extraction phase. At this step, drugs are isolated from hair at much lower levels than alternative methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to perform.

Confirmation of any positive screen employs techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive undergo washing before confirmation when necessary. The entire process, from Accessioning to Confirmation, is examined following both the CAP (College of American Pathologists) Hair designation and the standards set by ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug testing can identify drug usage for up to 90 days, unlike urine tests that offer a narrower detection period.
• Difficulty to cheat: It is exceptionally difficult to circumvent a hair drug test, which enhances the accuracy of the results.
• Provides historical data: It can show a timeline of drug consumption over a duration, not only recent intake.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair after an estimated 5-7 days.
• Cost: Hair drug tests often carry a higher price than other drug testing options.
• Variations in results: Differences in hair color and unique growth rates can impact drug metabolite concentrations within the hair.

Note: Although frequently termed "hair follicle tests", the test actually examines the hair strand itself, not 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.
