Hair Follicle Drug Testing - Cove, OR

What it is, How it works

Hair testing has gained recognition as a potent method for detecting drug and alcohol consumption. Hair offers a comprehensive history of alcohol and drug use by capturing biomarkers within the strands of growing hair. When collected near the scalp, hair can reveal a detection window of up to roughly three months for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.

The ideal sample for screening and confirmation consists of a 1.5-inch segment of approximately 200 hair strands (roughly the size of a #2 pencil), yielding 100mg of hair. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advisable. Use a jeweler’s scale for precise measurement. If scalp hair is unavailable, a comparable quantity of body hair may be used. Head hair specifically refers to scalp hair only, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test comprises four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails incorporating a sample into a laboratory’s system, which includes confirming proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.

Screening involves an initial rapid evaluation for drugs of abuse. Although Screening cost-efficiently rules out drug use in most cases, a positive result requires confirmation to be court-admissible. Presumptively positive samples in Screening necessitate secondary confirmation.

In the event of a presumptive positive result during the Screening phase, more hair is extracted from the initial specimen for the Extraction stage. Here, drugs are extracted from hair at a much lower concentration than in alternative methodologies (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleansed before confirmation when necessary. The entire process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests have a detection window of up to 90 days, in contrast to urine tests that offer a shorter timeframe.
• Challenge to cheat: The difficulty of tampering with a hair drug test ensures more accurate results.
• Historical data provision: It offers a pattern of drug use across time, rather than merely recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair roughly 5-7 days after use.
• Cost: Typically, hair drug tests entail higher expenses compared to other drug testing methods.
• Result variations: Factors like hair color and individual differences in hair growth can influence drug metabolite concentration in the hair.

Note: Although commonly termed "hair follicle tests", the analysis targets the hair strand itself, 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.
