Hair Follicle Drug Testing - Rio Rico Northeast, AZ

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. Hair offers a prolonged history of alcohol and drug intake by embedding biomarkers within the strands' fibers. When obtained near the scalp, hair can reveal usage of alcohol and other substances over a period of up to roughly three months. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch segment of roughly 200 hair strands (resembling the thickness of a #2 pencil) closest to the scalp delivers 100mg, which is the optimal amount for initial and confirmatory screenings. For EtG, additional tests, and/or evaluations exceeding 10 panels, a specimen weighing 150mg is advised. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair cannot be obtained, a corresponding volume of body hair may be used. The term "head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair (facial, axillary, etc.).

Process Overview

The primary stages in processing a lab drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a lab’s protocol, ensuring the sample was sealed and shipped appropriately, assigning a LAN (Laboratory Accessioning Number), and completing any residual data entry not available through an electronic chain of custody system.

Screening offers an initial, expedient assessment for substance abuse. While Screening is a cost-efficient approach for excluding drug use in most specimens, a positive result must be verified for legal admissibility. Samples with a presumptive positive outcome during Screening necessitate a follow-up confirmation.

For samples that screen positively, additional hair is drawn from the initial collection for the Extraction phase. In this phase, drugs are isolated from hair at a lower concentration compared to other techniques (e.g., urine or oral fluids), which is why hair drug analysis is deemed the most challenging to conduct.

Confirming any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed prior to confirmation as required. The entire lab procedure, from Accessioning to Confirmation, is scrutinized in alignment with the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 certification standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can uncover drug usage for as long as 90 days, unlike urine tests which detect recent usage.
• Hard to manipulate: Tampering with hair drug tests is challenging, thus enhancing result accuracy.
• Reveals usage patterns: It illustrates a drug usage pattern over time, not solely recent usage.

Limitations:

• Lacks recent usage detection: Drugs appear in hair about 5-7 days after use.
• Higher cost: Hair drug assessments generally incur higher expenses than other testing methods.
• Result variability: Hair color and individual hair growth differences can influence metabolite concentration in hair.

Note: Despite being called "hair follicle tests," the actual test evaluates 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.
