Hair Follicle Drug Testing - Wastella, TX

What it is, How it works

Hair analysis is now recognized as a robust means for detecting the use of drugs and alcohol. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers within the strands as they grow. When collected near the scalp, hair can reveal drug and alcohol use up to a nearly 3-month timeframe. The collection of hair is straightforward, relatively challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches of around 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, considered the optimal quantity for testing and verification. For EtG, supplemental tests, and/or tests beyond 10 panels, 150mg of the sample is advised. We advise using a jeweler’s scale for weighing the sample. If scalp hair is not available, an equivalent measure of body hair can be gathered. When specifying head hair, it pertains solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is entered into the laboratory's systems. This step involves verifying the sample’s proper sealing and shipment, allocating a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry needed absent an electronic chain of custody system.

Screening is a preliminary rapid assessment for drugs of abuse. While Screening provides a cost-efficient method to exclude drug use in most samples, positive screens must be verified to be legally acceptable. Samples that are provisionally positive during Screening require subsequent confirmation.

Should a sample be provisionally positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. At this stage, drugs are extracted from the hair at a concentration significantly lower than those found in other testing methodologies (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies to conduct.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed ahead of confirmation as necessary. The complete laboratory protocol from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation along with the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug tests have the capability to detect drug use for as long as 90 days, unlike urine tests that have a more short-term detection range.
• Challenging to deceive: The results of a hair drug test are more reliable, as it poses high difficulty to manipulate the test.
• Historical data provision: It reveals drug use patterns over a time span, rather than just recent usage.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair typically after 5-7 days post-use.
• Expense: Hair drug tests usually carry a higher price than other drug testing techniques.
• Result variations: Influences such as hair color and individual hair growth variations can alter the concentration of drug metabolites within hair samples.

Note: Frequently referred to as "hair follicle tests," these tests analyze 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.
