Hair Follicle Drug Testing - Wien, WI

What it is, How it works

Hair testing is now recognized as an effective means for identifying drug and alcohol consumption. Hair acts like a historical archive for these substances by encapsulating biomarkers within the hair fibers as they grow. Samples collected near the scalp can detect alcohol and drugs for a period of up to roughly 3 months. The process of collecting hair is straightforward, challenging to tamper with, and convenient for shipping.

A 1.5-inch portion with approximately 200 strands (akin to the size of a #2 pencil) from near the scalp will produce 100mg of hair, which is ideal for both screening and confirmation tests. For tests such as EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale for weighing is recommended. If scalp hair isn't an option, an equivalent quantity of body hair is acceptable. The term 'head hair' specifically means scalp hair only, whereas 'body hair' includes all other hair types (facial, axillary, etc.).

Process Overview

The key stages in laboratory drug testing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning focuses on the initial sample processing within a lab’s system. This step ensures the sample is sealed and correctly shipped, allocates a unique LAN (Laboratory Accessioning Number), and completes any missing data input not covered by an electronic chain of custody.

Screening provides an initial assessment for drug misuse. Although cost-effective, Screening must be followed by a confirmation to hold up in legal contexts. Samples with presumptive positive screens proceed to a secondary confirmation phase.

When a sample tests as a presumptive positive in Screening, additional hair is taken from the original sample for Extraction. During this phase, hair-based drug extraction occurs at lesser concentrations than other methods, such as urine or oral fluid, making hair drug screening a more complex procedure.

GC/MS, GC/MS/MS, or LC/MS/MS techniques carry out Confirmation for any positive screen results. Before confirmation, all presumptive positive samples undergo necessary washing. From Accessioning to Confirmation, the laboratory process is reviewed according to CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can reveal drug consumption for 90 days, exceeding the shorter detection spans of urine tests.
• Cheating deterrent: Cheating a hair drug test is notably difficult, ensuring higher result accuracy.
• Historical insight: It offers a timeline of drug usage across a span, not merely recent activity.

Limitations:

• Recent use detection: Drugs require approximately 5-7 days post-consumption to appear in hair samples.
• Cost factor: Hair drug tests generally incur higher costs than other testing methods.
• Result variability: Differences like hair color and individual hair growth can affect metabolite concentrations in hair.

Note: Despite being often called "hair follicle tests", these tests actually evaluate the hair strand rather than the root 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.
