Hair Follicle Drug Testing - Clover Creek, WA

What it is, How it works

Hair analysis is now recognized as an effective method for identifying alcohol and drug consumption. Hair retains a comprehensive record of substance intake by embedding biomarkers within the strands' fibers. When hair is sampled near the scalp, it offers roughly a 3-month window for detecting substances. Collecting hair is straightforward, hard to tamper with, and convenient for shipping.

An ideal test sample consists of a 1.5-inch segment of about 200 hair strands (comparable in size to a #2 pencil) nearest the scalp, yielding 100 mg, perfect for initial screening and verification. For EtG, additional tests, and/or those exceeding 10 panels, a 150 mg sample is advisable. Using a jeweler's scale is recommended to weigh the sample. If scalp hair is not available, the collection of an equal mass of body hair is permissible. In references to head hair, it specifically means scalp hair. Body hair denotes all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result encompasses four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the lab's system, ensuring the sample is sealed and transported correctly, generating a random LAN (Laboratory Accessioning Number), and completing any additional data input absent from an electronic chain of custody system.

Screening serves as a preliminary evaluation for drug presence. Though cost-efficient in excluding drug presence for most samples, a positive finding in Screening requires confirmation before legal admissibility. Samples with presumptive positivity in Screening necessitate secondary verification.

Should a sample test presumptively positive in Screening, further hair is extracted from the original specimen for the Extraction phase. Here, substances are removed from hair at notably inferior concentrations relative to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique to execute.

Verification of positive Screening outcomes is pursued using GC/MS, GC/MS/MS or LC/MS/MS techniques. Presumptive positive samples undergo washing prior to confirmation as required. The comprehensive lab process from Accessioning through to Confirmation is subject to review under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of Hair Drug Testing:

• Extended detection window: Hair drug tests identify drug usage for up to 90 days, surpassing the shorter detection span of urine tests.
• Challenge to manipulate: Successfully deceiving a hair drug test is exceedingly difficult, enhancing result reliability.
• Provides historical patterns: Offers insight into drug usage trends over time, not merely recent intake.

Limitations:

• Incapability to detect recent usage: Drugs typically become detectable in hair after roughly 5-7 days.
• Higher cost: Hair drug tests tend to be more costly than alternative testing methodologies.
• Result variability: Concentrations of drug metabolites in hair can be influenced by hair color and individual hair growth differences.

Note: Commonly named "hair follicle tests", these tests examine the hair strand, 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.
