Hair Follicle Drug Testing - Blackduck, MN

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the hair strand as it grows, hair offers a comprehensive history of alcohol and drug use over an extended period. Sampling hair close to the scalp can reveal a detection window for alcohol and other substances that extends up to nearly three months. The collection process for hair is straightforward, somewhat tamper-resistant, and convenient for shipping.

A sample of hair measuring 1.5 inches with approximately 200 strands (about the thickness of a #2 pencil) taken from near the scalp provides a 100mg quantity, which is optimal for both screening and validation. For EtG, add-ons, and/or analyses exceeding 10 panels, a specimen amount of 150mg is advised. A jeweler’s scale should be used to verify the sample’s weight. In cases where scalp hair cannot be obtained, an equivalent quantity of body hair is an alternative. Head hair strictly refers to scalp hair, whereas body hair encompasses all other types such as facial and axillary hair.

Process Overview

The four primary stages in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial administration of a sample within a laboratory’s framework. This stage ensures the sample is correctly sealed and dispatched, assigns a LAN (Laboratory Accessioning Number) at random, and completes any missing data entry not covered by an electronic chain of custody tool.

Screening acts as a preliminary evaluation for detecting substances of abuse. Although a Screening is a budget-friendly approach to dismissing drug use in the majority of cases, any positive result requires confirmation to be accepted legally. Samples with presumptive positive results in Screening necessitate a secondary confirmation.

Should the Screening stage indicate a presumptive positive, additional hair is drawn from the initial sample for the Extraction phase. In Extraction, substances are drawn out from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), which is a reason hair drug testing is particularly challenging to conduct.

GC/MS, GC/MS/MS, or LC/MS/MS techniques confirm any positive results detected in screening. All samples considered presumptively positive undergo necessary washing before confirmation. This entire laboratory process, from Accessioning through to Confirmation, is conducted under the scrutiny of CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days compared to urine tests, which offer a less extensive detection window.
• Low likelihood of misleading results: The integrity of hair drug tests is high, rendering it highly challenging to falsify the outcomes.
• Patterns over time: Hair testing captures a timeline of substance use rather than just recent incidents.

Limitations:

• Recent use detection: A delay of approximately 5-7 days is needed for drugs to be perceptible within hair.
• Expense: Hair drug testing is typically more costly than alternative drug testing measures.
• Variable results: Differences in hair properties, like color and individual hair growth rates, may influence the drug metabolite levels in hair.

Note: Despite the term "hair follicle tests" being employed, the procedure scrutinizes the hair itself and 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.
