Hair Follicle Drug Testing - Villa Verde, TX

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged timeline of substance usage by trapping biomarkers within the strands as they grow. When hair is collected near the scalp, it can show evidence of alcohol and drugs for up to about three months. The collection of hair is uncomplicated, resists tampering, and is straightforward to transport.

Acquiring a 1.5-inch section of approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest the scalp will yield 100mg of hair, which is ideal for both screening and confirmation processes. For EtG, additional tests, or panels exceeding 10, a sample weighing 150mg is advised. We recommend using a jeweler’s scale to weigh the sample. If scalp hair cannot be obtained, a comparable quantity of body hair may be used. When mentioning head hair, it refers solely to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

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

During Accessioning, the sample undergoes initial processing into the lab’s system. This step ensures that the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not covered by an electronic chain of custody system.

Screening provides an initial rapid assessment for the presence of substances. While cost-efficient and suitable for ruling out the majority of drug usage, a positive result necessitates further verification to be legally admissible. Samples that preliminarily test positive during screening must undergo secondary confirmation.

In cases where the sample is preliminarily positive in Screening, additional hair is extracted from the original sample and prepared for Extraction. In this process, the substance is extracted from the hair at much lower concentrations than other methods (such as urine or oral fluid), making hair drug screening one of the most challenging methods to execute.

Confirmation of any positive results from screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive are washed as needed before confirmation. The entire laboratory procedure, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug testing can reveal drug use over a 90-day period, as opposed to urine tests, which offer a shorter window.
• Difficult to falsify: It is notably challenging to manipulate hair drug test results, thus enhancing accuracy.
• Provides historical insight: It can outline a timeline of substance use, not merely recent activity.

Limitations:

• Inability to detect recent use: It generally takes between 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug testing is usually more costly than other methods of drug testing.
• Result variability: Variables such as hair color and personal differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Commonly termed "hair follicle tests", the analysis actually focuses on the strands of hair rather than the follicles below the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
