Hair Follicle Drug Testing - Allisonia, VA

What it is, How it works

Hair analysis is increasingly regarded as an effective means for identifying drug and alcohol consumption. As hair grows, it captures biomarkers within its strands, offering a prolonged timeline of substance use. By collecting hair proximal to the scalp, it can reveal drug and alcohol intake for up to a 3-month duration. Hair samples are straightforward to gather, challenging to tamper with, and simple to transport.

A hair sample measuring 1.5 inches in length and consisting of approximately 200 strands (around the thickness of a #2 pencil) located nearest the scalp yields roughly 100mg, the optimal sample volume for testing and validation. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is advisable. It's suggested to use a jeweler's scale for precise measurement. If scalp hair cannot be obtained, a comparable quantity of body hair is acceptable. "Head hair" specifically denotes scalp hair, whereas "body hair" encompasses all other varieties (such as facial or armpit hair).

Process Overview

The primary stages in laboratory processing for drug testing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a specimen into the lab's system. This phase involves verifying correct sealing and delivery of the sample, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entries absent in an electronic chain of custody system.

Screening entails a preliminary swift assessment for illicit drugs. Although Screening is an economical approach to excluding drug use in most samples, any positive result requires validation to be legally acceptable. Presumptive positives from Screening necessitate subsequent verification.

When a sample is presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction process. During this phase, drugs are retrieved from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug analysis one of the more intricate methodologies to execute.

Positive results upon screening are validated via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo a cleansing process prior to verification as necessary. The complete lab workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug assessments can identify drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Difficult to manipulate: Cheating a hair drug evaluation is quite hard, thereby improving the reliability of the results.
• Historical usage data: It provides a timeline of drug consumption over a longer duration, rather than just immediate use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair about 5-7 days after use.
• Expense: Hair drug evaluations are typically costlier than other methods.
• Result variability: Differences in hair pigmentation and individual hair growth variations may influence the concentration of drug residues.

Note: While commonly termed "hair follicle tests", the analysis targets the hair itself rather than the follicle below the scalp

Why Hair Follicle Testing Beats Urine Testing

In Allisonia, VA, hair follicle testing offers clear advantages over traditional urine tests. The main benefit is its unmatched detection accuracy. While urine tests detect drugs used in the past few days, hair tests reveal drug use up to 90 days prior. This is crucial in providing employers with a detailed overview of a person’s substance use patterns, ensuring reliability and dependability in screenings.

Extended Detection Window

The hair follicle test in Allisonia, VA stands out due to its extended detection window. Capturing drug use for up to 90 days, it provides an in-depth understanding of an individual's substance history. This extensive period helps employers make well-informed decisions, offering a thorough insight that is unattainable through shorter-detection tests.

Tamper-Resistant Testing Method

Hair follicle drug tests in Allisonia, VA are known for their tamper-resistant nature. Unlike other tests, where samples might be adulterated, hair samples offer robust evidence that’s hard to dispute. This ensures reliable results, reducing the threat of manipulation and providing confidence in the outcomes.

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.
