Hair Follicle Drug Testing - Caledonia, IL

What it is, How it works

Recognized widely, hair testing acts as an effective resource for uncovering drug and alcohol consumption. Hair captures a prolonged record of substances by sequestering biomarkers within the hair shaft as it grows. A sample cut near the scalp can reflect drug and alcohol intake over a timeline spanning up to 3 months. Hair collection is straightforward, fairly resistant to tampering, and conveniently ship-ready.

A hair sample measuring 1.5 inches including approximately 200 strands (akin to a standard #2 pencil) when clipped nearest to the scalp yields 100mg, the preferred quantity both for initial analysis and confirmatory testing. For EtG, additional assessments, or panels exceeding ten types, a 150mg sample is advisable. It is suggested to use a jeweler's scale for accurate measurement. In the absence of scalp hair, an equivalent mass of body hair is an acceptable substitute. References to head hair pertain specifically to scalp hair, while body hair encompasses all other types (such as facial or underarm hair).

Process Overview

In processing hair drug test results, the laboratory follows four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning kicks off the processing in a lab’s system. This stage includes checking that samples were sealed and sent under correct protocols, allocating a LAN (Laboratory Accessioning Number) number at random, and inputting any supplementary data needed beyond an electronic chain of custody.

Screening serves to quickly discern potential drug usage. It’s economical for most samples, but a positive outcome necessitates formal confirmation. Any samples registering presumptive positivity undergo additional verification.

Should a sample exhibit presumptive positivity during Screening, additional portions of the original sample are used for Extraction. Here, the task is to isolate drugs from hair at notably lower concentrations than alternative techniques (such as urine or oral fluid testing), underscoring the complexities of hair drug analysis.

Confirmation follows any positive Screening findings, through GC/MS, GC/MS/MS, or LC/MS/MS analyses. All preliminary positive samples undergo washing prior to final confirmation if required. Full procedural scrutiny—from Accessioning to Confirmation—occurs under both CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use across a 90-day timeframe, unlike shorter-term urine tests.
• Hard to falsify: Manipulating hair drug test results is quite challenging, ensuring accurate outcomes.
• Historical insight: Such tests reveal patterns of substance use spanning broader periods, not merely recent usage.

Limitations:

• No recent usage detection: Detectable levels of drugs in hair typically emerge after 5-7 days.
• Expense: Hair drug testing incurs higher costs compared to alternate testing strategies.
• Variable results: Elements like hair color and individual hair growth variability alter drug metabolite levels in hair samples.

Caution: Named "hair follicle tests", the procedure actually evaluates hair strands, not sub-scalp hair follicles.

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.
