Hair Follicle Drug Testing - North Beach, MD

What it is, How it works

Hair analysis has become recognized as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of substance use by securing biomarkers within the strands of growing hair. When collected close to the scalp, it can reflect up to roughly a 3-month detection period for drugs and alcohol. It's simple to gather, relatively challenging to alter, and straightforward for shipping.

A sample of 1.5 inches with roughly 200 strands of hair (equivalent to the thickness of a #2 pencil) nearest the scalp produces about 100mg, ideal for initial testing and confirmation. For tests like EtG, add-ons, or over 10 panels, 150mg is suggested. Using a jeweler’s scale for weighing the sample is advisable. If scalp hair isn't available, an equivalent quantity of body hair can be used. Head hair specifically refers to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

Laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed for a laboratory's system, ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody.

Screening serves as a preliminary check for substance abuse. Although cost-effective for ruling out drug use in most samples, a positive screen demands confirmation to be valid in court, and those presumptive positives require additional confirmation.

For samples presumptively positive in Screening, more hair is taken from the original sample for Extraction. Here, drugs are extracted from hair at much lower concentrations than other methods like urine or oral fluids, making hair drug screening particularly challenging.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and meets the accreditation of ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, unlike urine tests that have a shorter detection span.
• Difficult to tamper with: It's very hard to alter a hair drug test, ensuring more accurate outcomes.
• Offers historical insight: It provides a usage pattern over time, rather than just recent activity.

Limitations:

• Cannot detect recent activity: Drugs become detectable in hair after approximately 5-7 days.
• Cost: Hair tests are typically more costly than other drug testing methods.
• Result variations: Hair color and individual hair growth variances can impact drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests", the actual test examines the hair strand, not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing triumphs over traditional urine tests in North Beach, MD. While urine tests might catch very recent substance use, hair tests shine in detecting longer-term drug use. They offer far superior detection accuracy and reliability over extended periods.
This makes hair tests a preferred choice for organizations aiming for comprehensive substance detection, guaranteeing a thorough evaluation of an individual's substance use history.

Extended Detection Window

Employers in North Beach, MD, benefit from the extended detection window offered by hair follicle testing. Whereas urine tests might only detect drugs for several days, hair testing can identify drug usage within a 90-day window.
This comprehensive assessment assists employers in understanding an applicant or employee's long-term substance history, facilitating better-informed hiring or promotional decisions.

Tamper-Resistant Testing Method

The tamper-resistant qualities of hair follicle tests in North Beach, MD, are significant. By vastly reducing the likelihood of sample adulteration, these tests provide dependable and definitive outcomes.
This characteristic makes hair follicle testing a more reliable method compared to other tests that can be easily manipulated, ensuring organizations receive trustworthy results for informed decision-making.

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.
