Hair Follicle Drug Testing - Shields, MI

What it is, How it works

Seen as a potent instrument for detecting drug and alcohol consumption, hair testing has gained prominence. Hair traps biomarkers in the strands' fibers, offering a long-term history of substance use. When taken near the scalp, it can reveal drug and alcohol use for about three months. The collection process is straightforward, posing challenges for tampering, and the samples are easily shipped.

A 1.5-inch section (around the size of a #2 pencil) of roughly 200 hair strands near the scalp provides 100mg, an optimal amount for screening and validation. For EtG, addons, and tests beyond 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale to weigh the specimen. If not available, an equivalent amount of body hair can be collected. "Head hair" indicates scalp hair exclusively, while "body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

Four primary steps are crucial in processing drug test results: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the procedure of introducing a sample into a laboratory’s system. This step checks for proper sealing and shipment, assigns a LAN (Laboratory Accessioning Number), and completes any data entry not covered by electronic chain-of-custody systems.

Screening involves a preliminary assessment for drug presence. Although it's cost-efficient and effective for excluding drug use in many cases, any positive screening must be confirmed for legal acceptance. Samples that test presumptively positive need secondary confirmation.

If deemed presumptively positive during Screening, more hair is extracted from the original sample for Extraction. Drugs are extracted from hair specimens at lower concentrations than other methods (e.g., urine or saliva), making hair drug screening highly challenging.

GC/MS, GC/MS/MS, or LC/MS/MS methods confirm positive screenings. Presumptive positive samples are cleaned before confirmation when necessary. The lab process, from Accessioning to Confirmation, is scrutinized under both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug use for up to 90 days, surpassing the shorter periods detected by urine tests.
• Resistance to tampering: Cheating a hair drug test is exceptionally challenging, ensuring more reliable results.
• Provides usage history: Unlike tests for recent use, it illustrates patterns of drug use over time.

Limitations:

• Cannot identify recent usage: Detecting drugs in hair takes around 5-7 days post-use.
• Costly: Hair drug tests typically incur higher costs than other testing techniques.
• Outcome variations: Hair color and individual growth differences can influence drug metabolite concentration in hair.

Note: Often termed “hair follicle tests,” these tests analyze hair strands rather than the follicles 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.
