Hair Follicle Drug Testing - Henrietta, TX

What it is, How it works

Hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair strands capture biomarkers that reveal drug and alcohol usage over extended periods. When collected close to the scalp, hair can offer nearly a 3-month window for detecting alcohol and other drugs. This method of collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch sample containing roughly 200 hair strands (similar in size to a #2 pencil) taken from the scalp gives 100mg of hair, which is ideal for both screening and confirmation purposes. For tests like EtG, add-ons, or those exceeding 10 panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale for precise weighing. If scalp hair is inaccessible, a similar quantity of body hair can be used. "Head hair" refers only to scalp hair, and "body hair" covers all other types (e.g., facial, axillary).

Process Overview

The lab processing of a drug test result involves four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a laboratory's workflow. This step verifies the proper sealing and shipment of the sample, assigns a random Laboratory Accessioning Number (LAN), and completes any extra data entry not included in an electronic chain of custody system.

Screening serves as a preliminary assessment for drugs of abuse. While cost-effective for eliminating drug use in most samples, a positive screening outcome requires confirmation to be valid in legal proceedings. Any samples deemed presumptively positive during Screening require further confirmation.

For samples deemed presumptively positive at the screening stage, additional hair is extracted from the original sample for Extraction. This involves extracting drugs at lower concentrations compared to methods like urine or oral fluid testing, making hair drug screening one of the most intricate methodologies.

Confirmation of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. A complete review of the laboratory process from Accessioning to Confirmation is carried out under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a limited detection window.
• Hard to manipulate: Cheating a hair drug test is challenging, thus producing more reliable results.
• Tracks usage history: It provides a timeline of drug usage, indicating patterns rather than just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests are typically pricier than other drug-testing methods.
• Result variability: Hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the analysis is conducted on the hair strand, not 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
