Hair Follicle Drug Testing - Bunkie, LA

What it is, How it works

Hair testing is increasingly regarded as a robust method for identifying drug and alcohol consumption. Hair captures a historical record of substance use by embedding biomarkers within the strands as they grow. When sampled near the scalp, hair can offer a detection timeline for substances extending up to roughly three months. It is easy to gather, challenging to tamper with, and straightforward to transport.

A 1.5-inch segment of about 200 hair strands (comparable to a #2 pencil) closest to the scalp yields 100mg of hair, which is the prime sample amount for analysis and confirmation. For EtG, add-ons, or tests beyond 10 panels, a sample weighing 150mg is advisable. We recommend using a jeweler’s scale for weighing. If scalp hair is unobtainable, an equivalent quantity of body hair can be used. Our reference to head hair pertains only to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into the lab system. This includes ensuring the sample's proper sealing and shipping, assigning a LAN (Laboratory Accessioning Number), and completing any required data input absent in an electronic chain of custody system.

Screening provides a preliminary check for drugs of abuse. While it's an economical method to negate drug use in most cases, a positive screen must be verified to be legally valid. Samples testing presumptively positive in Screening require further confirmation.

Should a sample test positive during Screening, additional hair is extracted from the initial batch for the Extraction process. In this stage, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

All positive results from Screening undergo confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation if necessary. The laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair specification and the ISO/IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Extended detection period: Hair tests can detect substances for up to 90 days, in contrast to urine tests, which have a shorter detection range.
• Challenging to deceive: It's exceedingly difficult to falsify a hair drug test, ensuring more reliable results.
• Historical insight: It offers a timeline of substance use rather than recent usage alone.

Limitations:

• Unable to detect recent usage: It takes around 5-7 days for substances to become traceable in hair.
• Expense: Hair drug testing tends to be costlier than alternative testing strategies.
• Result variations: Variables such as hair color and individual growth differences can influence metabolite concentrations in hair.

Note: While commonly called "hair follicle tests," the analysis involves the hair strand itself, excluding the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Bunkie, LA, hair follicle testing is often preferred over urine tests due to its superior detection capability. Advantages of Hair Testing: Hair samples provide a wider detection window, revealing substance use up to 90 days prior, while urine tests are limited to recent consumption. Reliability: Hair tests are almost tamper-proof, unlike urine tests, which are susceptible to tampering, providing more true and reliable results.

Extended Detection Window

Employers in Bunkie, LA, value extended detection periods when choosing drug tests. Hair follicle testing provides an in-depth history of substance use by identifying drugs used up to 90 days before the test. Comprehensive Insight: Unlike urine tests that cover recent consumption, hair testing offers a broader view, which can be crucial for individuals undergoing evaluations for important employment decisions.

Tamper-Resistant Testing Method

Hair follicle assessments are a tamper-resistant method of drug testing favored by Bunkie, LA. These tests limit the possibility of sample adulteration or substitution. By utilizing hair, typically from the crown, the collection process reduces risks associated with cheating. Unquestionable Results: Employers and agencies trust this method for its secure and accurate outcomes, which cannot be easily manipulated compared to urine tests.

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.
