Hair Follicle Drug Testing - Fort Apache, AZ

What it is, How it works

Hair testing is recognized as an influential tool in detecting drug and alcohol usage. Hair captures a lengthy history of alcohol and drug intake by embedding biomarkers within the strands of hair as it grows. If collected near the scalp, hair can offer nearly a 3-month detection period for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.

A sample consisting of 1.5 inches of about 200 hair strands (approximately the diameter of a #2 pencil) next to the scalp provides 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, add-ons, or tests surpassing 10 panels, a 150mg specimen is advised. A jeweler's scale is suggested for weighing the specimen. If scalp hair is not accessible, an equivalent amount of body hair can be utilized. When talking about head hair, it specifically refers to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory process of a drug test result consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initiation of processing a sample into a laboratory’s setup, ensuring verification of proper sealing and shipping, allotting a random LAN (Laboratory Accessioning Number), and fulfilling any data entry not done by an electronic chain of custody system.

Screening performs an initial rapid evaluation for substance abuse. Although Screening offers a cost-efficient method to exclude drug usage on most samples, a positive screen necessitates confirmation to be court-admissible. Samples showing presumptive positive in Screening must undergo further confirmation.

If the Screening stage results in a presumptive positive, additional hair from the original specimen is set aside for Extraction. In this phase, drugs are extracted from hair, which has a much lower concentration as opposed to other methods (e.g., urine or oral fluid), thereby making hair drug screening notably complex.

Confirmation of any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleansed before confirmation when required. The complete lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug usage extending to 90 days, whereas urine tests cover a shorter span.
• Challenging to manipulate: Cheating a hair drug test is notably difficult, ensuring more accurate results.
• Shows historical usage: Offers a trace of drug usage over time, beyond just immediate use.

Limitations:

• Inability to detect recent usage: Drugs take about 5-7 days to appear in hair.
• Expense: Hair drug tests are typically costlier compared to other testing techniques.
• Result variability: Elements like hair color and personal hair growth differences can influence drug metabolite concentrations in the hair.

Note: Commonly called "hair follicle tests", the test inspects the hair strand, not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Fort Apache, AZ, offers distinct advantages over traditional urine tests. While urine tests may cover recent substance use, hair testing provides a broader detection range with its ability to identify drug intake over a longer period. This superior accuracy and consistent reliability make hair testing a more effective method for employers aiming to enforce zero-tolerance policies.

Extended Detection Window

Hair follicle testing in Fort Apache, AZ, captures drug usage history over an extended timespan of up to 90 days. This comprehensive detection window offers employers invaluable insights into an individual's substance use patterns, helping them make informed decisions about potential or current employees based on long-term behavior rather than isolated incidents.

Tamper-Resistant Testing Method

Hair follicle tests conducted in Fort Apache, AZ, greatly minimize the risk of adulteration or tampering. Unlike other testing methods, hair samples are harder to manipulate or substitute, ensuring that the results remain valid and uncontaminated. This reliability makes hair testing a trusted approach for organizations seeking indisputable evidence of substance use.

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.
