Hair Follicle Drug Testing - Koehler, NM

What it is, How it works

Hair testing is increasingly regarded as an effective method for identifying substance and alcohol usage. Hair can encapsulate biomarkers within the strands as it grows, thus providing an extended history of substance and alcohol consumption. When gathered close to the scalp, hair offers nearly a 3-month detection window for such substances. Hair collection is straightforward, poses challenges to adulteration, and is uncomplicated to transport.

A segment of hair measuring 1.5 inches, consisting of roughly 200 strands (similar in thickness to a #2 pencil) and closest to the scalp, supplies 100mg of hair, which is the optimum sample size for both screening and confirmation tests. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be used. When addressing head hair, it exclusively refers to scalp hair. Body hair encompasses any other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result consists of four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial incorporation of the sample into the lab system. This step involves ensuring the sample was correctly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and completing any further data entry necessary beyond what an electronic chain of custody system would provide.

Screening serves as a preliminary assessment for substance presence. Although cost-effective for initially detecting drug use in most samples, a positive result during Screening needs further confirmation for legal admissibility. Presumptive positive samples in Screening necessitate a second validation stage.

If a sample tests presumptively positive during Screening, additional hair is sourced from the original specimen for the Extraction phase. Here, substances are drawn from hair at far lower concentrations compared to other methods (e.g., urine or saliva), a complexity that makes hair drug testing one of the most challenging methodologies.

The Confirmation of any positive result post-Screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive are washed before undergoing confirmation as required. Each step from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use spanning up to 90 days, contrary to the shorter detection period in urine tests.
• Resistance to tampering: The challenge in deceiving hair drug tests contributes to more reliable outcomes.
• Historical insight: It can delineate a pattern of substance use over an extended timeline, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug testing tends to be costlier than alternative testing methods.
• Variability in results: Attributes like hair pigmentation and individual hair growth variability can influence the drug metabolite levels in hair.

Note: Although sometimes called "hair follicle tests", the analysis targets the hair strand itself rather than 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.
