Hair Follicle Drug Testing - Leo, TX

What it is, How it works

Hair assays have gained prominence as an effective method for detecting substance and alcohol consumption. Hair serves as a retrospective indicator for alcohol and drugs by embedding biomarkers within the structure of a growing strand. When sampled near the scalp, hair offers a detection span of up to roughly three months for alcohol and drugs. The collection is straightforward, relatively resistant to tampering, and easy to transport.

A segment of 1.5 inches comprising approximately 200 hair strands (similar to a #2 pencil in size) adjacent to the scalp yields 100mg of hair, which is optimal for testing and confirmation. For EtG, additional components, or tests exceeding 10 panels, a sample of 150mg is advised. Measurement of the sample using a jeweler’s scale is recommended. If scalp hair is not available, an equivalent quantity of body hair can be taken. References to head hair specify only scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a specimen into a lab’s framework. This process confirms the sample’s proper sealing and delivery, assigns a unique LAN (Laboratory Accessioning Number), and completes additional data entry if not supplied by an electronic chain of custody system.

Screening executes a preliminary rapid evaluation for controlled substances. While this step economically excludes drug presence in most specimens, positive screens necessitate confirmation for legal acceptability. Any indicative positives from Screening mandate further validation.

For samples preliminarily positive during the Screening phase, additional hair is extracted from the original sample and prepared for Extraction, where substances are isolated at a much lower concentration than in other methods (such as urine or oral fluid), posing the greatest challenge in hair drug analysis.

Confirmation of any presumptive positive findings is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with preliminary positive results are cleansed before confirmation as needed. The comprehensive laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and accreditation to meet ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection range: Hair tests reveal substance use for up to 90 days, unlike urine tests, which feature a reduced detection period.
• Challenging to manipulate: Hair tests resist manipulation, resulting in more reliable outcomes.
• Yields historical insights: The test can illustrate consumption patterns over time, instead of just recent usage.

Limitations:

• Incapable of detecting recent use: Drugs typically take 5-7 days to become detectable in hair.
• Expense: Hair tests tend to be costlier compared to other drug testing techniques.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often labeled "hair follicle tests," the test specifically examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Leo, TX, hair follicle testing significantly outperforms traditional urine testing. While urine tests can detect recent drug use, hair tests offer a more accurate and reliable approach.

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.
