Hair Follicle Drug Testing - Swedesburg, IA

What it is, How it works

Hair testing has become acknowledged as an effective means for detecting drug and alcohol consumption. The hair retains a lengthy historical record of alcohol and other drugs by capturing biomarkers within the strands' fibers as they grow. When retrieved from near the scalp, hair can reveal up to a 3-month approximation for detecting alcohol and additional drugs. Its collection is uncomplicated, moderately challenging to tamper with, and straightforward to transport.

A sample measuring 1.5 inches consisting of roughly 200 hair strands (comparable to a #2 pencil) nearest the scalp yields 100mg of hair, which is optimal for initial screening and verification. For procedures such as EtG, extra tests, or those exceeding 10 panels, it is advised to collect 150mg of the specimen. We suggest evaluating the weight using a jeweler’s scale. Should scalp hair be unavailable, a proportionate amount of body hair can be gathered. When mentioning head hair, it pertains strictly to scalp hair. Conversely, body hair encompasses all remaining types (such as facial, axillary, etc.).

Process Overview

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

Accessioning covers the preliminary processing where a sample is integrated into a lab’s records. This step includes ensuring the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and performing any extra data logging not supplied by an electronic chain of custody system.

Screening is conducted as an initial rapid evaluation for drugs of abuse. Though it is cost-effective for excluding drug usage in most cases, a positive screen must be confirmed to be court-admissible. All samples yielding a presumptive positive in Screening necessitate further confirmation.

In instances with presumptive positive samples during the Screening phase, additional hair is extracted from the original specimen for the Extraction process. Here, drugs are removed from hair at concentrations much lower than in other techniques (e.g., urine or oral fluid), rendering hair drug screening the most complex method to execute.

Confirmation for any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation as required. The entire laboratory procedure, from Accessioning to Confirmation, is evaluated per both the CAP (College of American Pathologists) Hair standard and accreditation under ISO / IEC 17025 guidelines.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests identify drug use for up to 90 days, surpassing the shorter detection span of urine tests.
• Challenging to manipulate: Cheating a hair drug test is considerably difficult, thus enhancing result accuracy.
• Provides consumption patterns: Offers insight into patterns of drug use over time, beyond mere recent use.

Limitations:

• Non-detection of recent use: Drugs become detectable in hair only after approximately 5-7 days.
• Higher cost: Hair drug testing is usually more costly compared to alternative methods.
• Result variability: Aspects such as hair color and personal variations in hair growth might affect metabolite concentrations in hair.

Note: Although often termed as "hair follicle tests," the analysis targets 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.
