Hair Follicle Drug Testing - Bishop Hills, TX

What it is, How it works

Hair testing is recognized as an effective method for detecting the use of drugs and alcohol. Hair strands record a long-term usage of alcohol and drugs by capturing biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can show substance use for up to about three months. Hair specimens are easy to collect, relatively hard to tamper with, and straightforward to send.

A sample measuring 1.5 inches, approximately 200 strands (resembling the width of a #2 pencil), taken nearest the scalp offers around 100mg of hair, ideal for both screening and confirmation purposes. For tests involving EtG, extra parameters, and/or panels exceeding ten, a specimen weighing 150mg is advised. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair can be utilized. "Head hair" pertains to scalp hair only, while "body hair" refers to all other hair types such as facial, axillary, etc.

Process Overview

The four primary stages in laboratory processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is integrated into a lab's system, ensuring the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent in an electronic chain of custody system.

Screening provides a preliminary swift evaluation for substances of abuse. Although a cost-effective method to exclude drug use in the majority of samples, positive results from screening need verification to be accepted legally. All samples marked presumptively positive in Screening require additional confirmation.

If Screening yields a presumptive positive, more hair is extracted from the original specimen for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations compared to other methodologies like urine or oral fluid, rendering hair drug testing a more challenging method to execute.

GC/MS, GC/MS/MS, or LC/MS/MS methods carry out the Confirmation of any positive screening outcome. Prior to confirmation, all presumptive positive samples undergo necessary washing. The entire laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation alongside accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can reveal drug use up to 90 days, unlike urine tests which have a shorter detection span.
• Cheating is challenging: It's very difficult to manipulate a hair drug test, ensuring more reliable results.
• Chronicles usage: Demonstrates a pattern of drug use over time, beyond mere recent consumption.

Limitations:

• Cannot reveal immediate use: A span of roughly 5-7 days is necessary for drugs to be traceable in hair.
• Expense: Hair drug tests tend to cost more than other drug detection methods.
• Result variability: Aspects like hair color and personal hair growth differences can impact drug metabolite concentration in the hair.

Note: Commonly referred to as "hair follicle tests", this test actually evaluates the hair strand, not the hair 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. 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.
