Hair Follicle Drug Testing - Troy, KS

What it is, How it works

Hair analysis is recognized as an influential method for identifying the use of drugs and alcohol. Hair encapsulates a prolonged history of substance usage by capturing biomarkers within the fibers of the developing hair strand. When procured near the scalp, hair can offer a detection period of up to approximately three months for alcohol and drugs. Hair is straightforward to collect, somewhat challenging to tamper with, and convenient to ship.

A sample measuring 1.5 inches, consisting of roughly 200 hairs (comparable to a #2 pencil's diameter) from near the scalp, yields 100mg of hair, the optimal amount for assessment and validation. For EtG, supplementary, and/or over 10-panel tests, 150mg of the specimen is advised. It's beneficial to weigh the sample on a jewelry scale. If scalp hair is not accessible, a similar quantity of body hair can be taken. Referencing head hair implies scalp hair exclusively. Body hair pertains to all other hair types (facial, axillary, etc.).

Process Overview

The fundamental steps in processing a drug test result in a laboratory are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a specimen within a laboratory’s framework. This process incorporates verifying that the specimen was appropriately sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and executing any extra data input absent in an electronic chain of custody system.

Screening provides an initial rapid assessment for drugs. While it is a cost-efficient method to negate drug consumption in the majority of samples, a positive result in Screening requires confirmation to be valid in court. Samples showing a presumptive positive in Screening necessitate a follow-up confirmation.

For any sample showing presumptive positivity in Screening, more hair is extracted from the initial sample for the Extraction process. During Extraction, drugs are removed from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), underscoring why hair drug testing is a complex approach to execute.

Verification of any positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity are cleansed before confirmation as required. The comprehensive laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use up to 90 days, whereas urine tests have a brief detection period.
• Challenge to manipulate: Manipulating a hair drug test is notably difficult, enhancing result accuracy.
• Provides usage history: This testing can depict usage trends over time, beyond just recent activity.

Limitations:

• Unable to identify recent usage: Drugs become detectable in hair within approximately 5-7 days.
• Expense: Hair drug tests are typically costlier than alternative drug testing methods.
• Result variability: Variability in outcomes can arise due to factors like hair color and individual growth differences.

Note: Although commonly termed as "hair follicle tests," the examination evaluates the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Troy, KS, hair follicle tests surpass urine tests thanks to their superior accuracy and extended detection window. Unlike urine tests, which may miss recent drug use, hair tests reveal patterns over a longer period, offering a more reliable assessment. These advantages make hair testing the preferred choice for employers and authorities aiming to ensure a drug-free environment.

Extended Detection Window

The extended detection window of hair follicle testing makes it a valuable tool in Troy, KS. While urine tests lose accuracy beyond a few days, hair tests can identify drug use up to 90 days prior. This extended period gives employers a fuller picture of substance history, aiding in informed decision-making concerning employment or treatment plans.

Tamper-Resistant Testing Method

Hair follicle testing is a tamper-resistant method in Troy, KS. Unlike urine samples which might be adulterated, hair samples provide a nearly foolproof means of ensuring test integrity. This reliability guarantees that results are both accurate and trustworthy, minimizing doubts about the authenticity of the findings.

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.
