Hair Follicle Drug Testing - Villanueva, NM

What it is, How it works

Hair analysis has evolved into a potent mechanism for detecting substance and alcohol use. Hair archives a lengthy history of alcohol and drugs by embedding biomarkers within the hair strand's growing fibers. When clipped near the scalp, hair can offer about a three-month timeframe for identifying alcohol and drugs. Hair is straightforward to collect, somewhat tough to tamper with, and easy to transport.

A 1.5-inch sample of roughly 200 hair strands (comparable in size to a #2 pencil) closest to the scalp will yield 100mg, an optimal sample for evaluation and confirmation. For EtG, extra panels, and/or tests exceeding 10 panels, a 150mg sample is suggested. It is advised to weigh the specimen using a jeweler’s scale. If the scalp hair is unavailable, a similar quantity of body hair can be acquired. When mentioning head hair, we're specifically indicating scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The principal steps in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into a lab’s framework. This step verifies the sample's proper sealing and shipping, allocation of a random LAN (Laboratory Accessioning Number), and completion of additional data entry not supplied by an electronic chain of custody system.

Screening comprises an initial rapid evaluation for drug presence. While Screening is a cost-effective strategy to dismiss drug usage in most samples, a positive outcome must be verified to be court-admissible. Samples that are presumptively positive in Screening require subsequent confirmation.

If Screening indicates a presumptive positive, additional hair is retrieved from the initial sample and readied for Extraction. In this phase, drug traces are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which is why hair drug screening is a challenging technique to execute.

Confirmation of any positive Screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The overall procedural flow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests which have a shorter detection span.
• Hard to falsify: It is extremely challenging to circumvent a hair drug test, enhancing result accuracy.
• Delivers historical insight: It can reveal a pattern of drug use over time, not just recent usage.

Limitations:

• Incapable of detecting recent usage: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug tests typically cost more than alternative drug testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Although often known as "hair follicle tests", the test evaluates the hair strand rather than the follicle beneath the scalp.

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.
