Hair Follicle Drug Testing - Blanco, TX

What it is, How it works

Hair testing is regarded as an effective method for identifying drug and alcohol consumption. Hair encapsulates a long-term record of substance use by capturing biomarkers within the fibers of the growing strand. When taken near the scalp, hair can offer roughly a 3-month detection timeframe for drugs and alcohol. Hair collection is straightforward, not easily tampered with, and simple to send.

A 1.5-inch segment of approximately 200 hair strands (about the diameter of a #2 pencil) close to the scalp yields 100mg, the optimal sample for both screening and confirmation. For EtG, additional tests, and/or screenings exceeding 10 panels, 150mg of hair is advisable. Using a jeweler’s scale to weigh the hair ensures accuracy. If scalp hair is not an option, an equivalent amount of body hair can be used. References to head hair specifically denote scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The process of laboratory analysis of a drug test result includes the stages of Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial sample integration into a lab's system. This step verifies the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.

Screening conducts a preliminary check for drugs of abuse. While Screening is an economical means to rule out drug use in most samples, any positive finding requires confirmation for it to be permissible in court. Samples that are presumptively positive during Screening require additional confirmation.

If a sample tests presumptively positive at the Screening phase, more hair is extracted from the initial sample and prepped for Extraction. Here, drugs are isolated from hair at much smaller concentrations compared to other methodologies (e.g., urine or oral fluid), illustrating why hair drug screening presents a challenge to perform.

Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS or LC/MS/MS. All samples presumed positive undergo washing before confirmation as needed. The complete lab procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation as well as accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Challenging to evade: Cheating in a hair drug test is exceedingly difficult, enhancing result accuracy.
• Supplies historical context: It provides insight into drug usage patterns over time, not merely recent usage.

Limitations:

• Incapable of detecting recent use: A timeframe of approximately 5-7 days is necessary for drugs to manifest in hair.
• Expense: Hair drug tests tend to incur higher costs than alternative drug testing methods.
• Result variability: Factors such as hair color and personal differences in hair growth can impact drug metabolite concentrations in hair.

Note: Despite often being named "hair follicle tests", the test itself assesses 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.
