Hair Follicle Drug Testing - Woodland, MD

What it is, How it works

Hair assessments are increasingly recognized for their effectiveness in identifying substance use. Hair can encapsulate biomarkers within its fibers, offering a comprehensive history of alcohol and other substances. When harvested near the scalp, hair can reveal substance use over an approximate three-month timeframe. This material is straightforward to gather, challenging to tamper with, and convenient for transport.

A segment measuring 1.5 inches with roughly 200 hairs (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal quantity for analysis and verification. For EtG, additional assessments, and tests exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample using a jeweler’s scale. If scalp hair is inaccessible, a comparable quantity of body hair can be retrieved. By head hair, we exclusively mean scalp hair. Body hair includes all other classifications (facial, axillary, etc.).

Process Overview

The key stages in the lab analysis of a drug test finding include Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the sample’s initial integration into the lab’s system. This process encompasses confirmation of the sample being securely sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing extra data logging absent in an electronic custody chain.

Screening begins with a preliminary drug abuse check. Though cost-effective for largely negating drug presence across most samples, any positive screens call for confirmation to stand in legal scenarios. Samples with positive presumption during Screening necessitate follow-up verification.

If presumed positive during Screening, additional hair from the original sample undergoes preparation for Extraction. This phase involves isolating drugs from hair at notably lower concentrations than methods like urine or oral fluids, underscoring the complexity of hair drug screening.

Verification of any positive screen outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before verification as required. Each lab phase from Accessioning to Confirmation falls under examination via CAP (College of American Pathologists) Hair criteria and is accredited to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

• Extended detection timeframe: Hair tests track drug usage for up to 90 days, surpassing urine tests with narrower windows.
• Hard to manipulate: Avoiding deception is challenging with hair tests, yielding more precise results.
• Chronicles usage over time: It charts a temporal pattern of substance consumption, encompassing more than just recent activity.

Limitations:

• Lacks immediate detection: Drugs generally take 5-7 days to register in hair.
• Expense: Hair tests typically incur higher costs than alternative drug-testing approaches.
• Result variability: Factors like hair color and individual growth differences can influence drug metabolite concentrations in hair.

Note: Often dubbed "hair follicle tests", the analysis pertains to the hair strand, excluding the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Woodland, MD, hair follicle testing offers numerous advantages over traditional urine tests. Accuracy and reliability are key factors why many prefer it. Hair testing provides a longer detection window, capturing drug use up to 90 days back. In contrast, urine tests have a shorter detection span and can be more easily compromised. Hair tests ensure a comprehensive view of an individual's substance use history.

Extended Detection Window

Employers in Woodland, MD benefit from hair follicle tests due to their extended detection window. Unlike urine tests, hair testing can detect drug use up to 90 days prior, providing a thorough picture of substance history. This longer window assists in making informed decisions regarding employment, offering a reliable insight into past behaviors and ensuring a trustworthy workforce.

Tamper-Resistant Testing Method

Sample integrity is a prevalent issue in drug testing, but hair follicle tests used in Woodland, MD provide a tamper-resistant solution. These tests significantly reduce the risk of adulteration due to their nature. Unlike urine samples, hair tests are difficult to manipulate, ensuring reliable and unquestionable results that enhance the credibility of the testing process.

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.
