Hair Follicle Drug Testing - Bertha, MN

What it is, How it works

Identified as an effective method for identifying drug and alcohol consumption, hair testing offers a prolonged account of substance use by embedding biomarkers within the strands as they grow. Upon gathering hair near the scalp, it can showcase a detection period of approximately 90 days for both alcohol and other substances. The collection process is straightforward, harder to tamper with, and convenient for transportation.

Acquiring a 1.5-inch section of roughly 200 hair strands (equivalent to the thickness of a #2 pencil) near the scalp yields 100mg of hair, an optimal amount for analysis and corroboration. When testing for EtG, additional substances, or employing more than 10-panel tests, a 150mg sample is advisable. We suggest using a jeweler’s scale for accurate measurement. Should scalp hair be absent, body hair of equal weight is acceptable. The term "head hair" implies scalp hair specifically, whereas "body hair" covers other types (such as facial and axillary).

Process Overview

The laboratory procedures for processing drug test samples encompass four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step wherein a sample is processed into the laboratory's system. This encompasses ensuring the sample is correctly sealed and sent, generating an arbitrary Laboratory Accessioning Number (LAN), and executing additional data entry absent from an electronic chain of custody arrangement.

Screening is a preliminary rapid evaluation for substances of abuse. Though it presents a cost-efficient method to negate drug presence in most samples, a positive indication from Screening necessitates further confirmation to hold up in legal settings. Samples yielding presumptive positives in Screening demand secondary verification.

Upon a presumptive positive result in Screening, more hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair in much lesser concentrations than found in other methods (e.g., urine or saliva), making hair drug screening notably challenging.

Positive outcomes from Screening undergo Confirmation through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed pre-confirmation as necessary. The entire laboratory protocol, spanning Accessioning to Confirmation, undergoes scrutiny under the guidelines of both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can reveal drug use up to 90 days, unlike urine tests which have a shorter detection span.
• Hard to falsify: It’s exceedingly difficult to falsify a hair drug test, thus ensuring more reliable results.
• Historical insight: It can provide a usage pattern over a prolonged span, unlike recent use data.

Limitations:

• Cannot capture recent use: It requires about 5-7 days before drugs become detectable in hair.
• Expensive: Hair drug tests typically incur higher costs compared to other testing alternatives.
• Result variations: Elements like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often termed as "hair follicle tests," the analysis focuses on the hair strand rather than the hair 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.
