Hair Follicle Drug Testing - Attalla, AL

What it is, How it works

Hair analysis is increasingly recognized as an effective means for detecting substance consumption. Hair retains drug and alcohol traces over a long period by embedding biomarkers within its growing fibers. When clipped near the scalp, hair can offer a detection window of up to approximately 90 days for various substances. Hair is easy to collect, relatively tamper-resistant, and simple to transport.

A collection of a 1.5-inch length consisting of roughly 200 hair strands (about the diameter of a #2 pencil) from the scalp yields 100mg of hair, suitable for assessment and verification. For EtG, additional tests, or those exceeding 10 panels, it is advisable to collect 150mg of the sample. We suggest measuring the sample with a jeweler’s scale. If scalp hair is insufficient, an equivalent quantity of body hair can be used. When mentioning head hair, we imply scalp hair specifically. Body hair includes all other types of hair (such as facial, axillary, etc.).

Process Overview

There are four principal stages in the laboratory evaluation of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of inputting a sample into a laboratory’s framework. This step includes ensuring the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not provided by an electronic chain of custody mechanism.

Screening involves a preliminary examination for abuse substances. While Screening offers a cost-effective solution to exclude drug consumption for most samples, a positive finding requires confirmation for legal admissibility. Presumptive positive samples in Screening necessitate a secondary verification.

Should a sample show presumptive positivity in Screening, additional hair is extracted from the original specimen for Extraction. This phase extracts drugs from hair at a notably lower concentration than other methods (e.g., urine or oral fluid), rendering it the most complex methodology for drug testing.

Any positive finding in the screening process is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positives undergo a washing process as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair tests can identify drug consumption for up to 90 days, unlike urine tests which possess a shorter detection period.
• Difficult to manipulate: It is challenging to tamper with a hair test, thus ensuring more reliable results.
• Offers historical insight: It provides a trend of drug consumption over a timeframe, rather than just recent intake.

Limitations:

• Inability to detect recent intake: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair tests are generally pricier compared to other methods of drug testing.
• Result variability: Factors such as hair pigment and individual growth variance can impact drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the analysis actually evaluates the strand of hair, not the follicle beneath the surface.

Why Hair Follicle Testing Beats Urine Testing

In Attalla, AL, hair follicle testing stands out over urine testing due to its superior detection capability.

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.
