Hair Follicle Drug Testing - Palo Verde, AZ

What it is, How it works

Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. The fibers of growing hair strands capture biomarkers, providing a chronic history of substance use. When hair is collected near the scalp, it offers a detection time frame of up to three months for alcohol and drugs. The process of collecting hair is uncomplicated, challenging to tamper with, and straightforward to send.

A 1.5-inch portion consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG, add-ons, or tests of more than 10 panels, a sample of 150mg is advisable. We suggest measuring the specimen using a jeweler's scale. If scalp hair cannot be obtained, a comparable amount of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning is the process that incorporates a sample into a laboratory system. This ensures the sample was properly sealed and transported, assigns a random Laboratory Accessioning Number (LAN), and completes any supplementary data not included by an electronic chain of custody system.

Screening is an initial inspection for illicit drugs. Though a cost-efficient approach to eliminate drug use in most samples, a positive screen necessitates confirmation to be legally valid. Any sample testing presumptively positive in Screening mandates secondary validation.

If Screening indicates a presumptive positive, additional hair is extracted from the primary specimen for the Extraction phase. Here, drugs are withdrawn from hair at notably lower levels than within other methods (e.g., urine or saliva), making hair drug testing the most challenging methodology to undertake.

Positive screen results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The complete lab process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect drug use for up to 90 days, unlike urine tests which have shorter detection times.
• Cheating is difficult: Cheating on a hair drug test is extremely hard, ensuring more reliable outcomes.
• Historical insights: It offers a portrayal of drug use trends over time, beyond just recent use.

Limitations:

• Inability to detect recent use: Drugs take about 5-7 days to become detectable in hair.
• Cost: Generally, hair drug tests are more costly than alternative drug testing methods.
• Result variability: Attributes such as hair color and personal hair growth differences can impact drug metabolite levels in hair.

Note: Although often called "hair follicle tests", the analysis is done on the hair strand and not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Hair vs. Urine Testing: Hair follicle analysis surpasses urine testing by offering a longer detection window and more reliable results. In Palo Verde, this method's accuracy and reliability prove essential for employers and agencies prioritizing drug-free environments.

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.
