Hair Follicle Drug Testing - Lydia, TX

What it is, How it works

Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of substance use by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can reveal up to about a 90-day timeline for detecting drugs and alcohol. This method is easy to obtain, somewhat resistant to tampering, and convenient to transport.

A 1.5-inch sample comprising around 200 hairs (approximately the thickness of a #2 pencil) from the scalp delivers 100mg, which is ideal for testing and validation. For EtG, additional tests, and/or screenings beyond 10 panels, a sample of 150mg is advised. Utilizing a jeweler’s scale to measure the sample is suggested. If head hair isn't available, a similar quantity of body hair can be substituted. By “head hair,” we mean only scalp hair. "Body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test outcomes includes four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing of a specimen in a laboratory's system. This includes ensuring the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finishing any extra data input that isn't automatically supplied by an electronic chain of custody system.

Screening entails a preliminary assessment for drugs of misuse. While it's a budget-friendly approach to exclude drug usage for most samples, a positive result requires validation to be court-admissible. Samples that show a preliminary positive in Screening must undergo further confirmation.

If a sample shows a preliminary positive in Screening, additional hair is taken from the initial sample for Extraction. In this stage, drug compounds are removed from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing one of the most challenging methodologies to carry out.

Confirmation of any positive screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples are cleansed beforehand if necessary. The entire lab procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and accreditation of ISO / IEC 17025 norms.

Benefits of hair drug testing:

• Extended detection period: Hair drug testing can uncover drug use up to 90 days, unlike urine tests that have a shorter period.
• Hard to falsify: Manipulating hair drug test results is challenging, enhancing result reliability.
• Gives a history: It depicts a timeline of drug use rather than just recent involvement.

Disadvantages:

• Cannot identify recent use: Drugs take about 5-7 days to become evident in hair.
• Costs: Hair drug testing tends to be pricier than other methods.
• Variability: Elements like hair color and individual growth rates can influence drug metabolite concentrations in the hair.

Note: The term "hair follicle tests" generally refers to tests on the hair strand, not the follicle beneath 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.
