Hair Follicle Drug Testing - Macomb, OK

What it is, How it works

Through innovative approaches, hair analysis is recognized as an effective means for identifying drug and alcohol consumption. The unique structure of hair retains biomarkers within its strands, offering an extensive timeline of substance use. Samples collected near the scalp can reveal drug and alcohol presence for up to three months. Collecting hair is straightforward, requires effort to tamper with, and is easy to transport.

A sample measuring 1.5 inches in length, consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil), can yield 100mg—ideal for conducting screening and providing confirmation. To execute additional tests, such as EtG add-ons or panels exceeding ten, a 150mg sample is advised. Using a jeweler's scale to weigh the sample is recommended. In the absence of scalp hair, an equivalent portion of body hair can be utilized. The term "head hair" specifically references scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The procedure for processing a drug test in the laboratory is segmented into four essential steps: Accessioning, Screening, Extraction, and Confirmation.

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

Screening is a preliminary check for substances of abuse. Though cost-effective and useful for excluding drug use in most cases, any positive results require further validation to be legally defensible. Presumptively positive screening samples mandate additional confirmation.

In cases where a sample tests presumptively positive during Screening, extra hair is extracted from the original sample for further analysis. The hair extraction process detects drugs at much lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.

Confirmation of positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation if necessary. The overall laboratory workflow, from Accessioning to Confirmation, is carefully evaluated under the CAP (College of American Pathologists) Hair designation alongside ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests provide a detection window of up to 90 days, surpassing the shorter timeframe of urine tests.
• Difficulty to cheat: Tampering with a hair drug test is highly challenging, increasing result reliability.
• Provides historical data: Offers insights into long-term substance patterns, extending beyond immediate use.

Limitations:

• Cannot detect recent use: Drugs become traceable in hair approximately 5-7 days after use.
• Cost: Compared to other methods, hair drug tests generally incur higher expenses.
• Variations in results: Drug metabolite concentrations in hair can be influenced by factors such as hair color and growth variability.

Note: Although frequently called "hair follicle tests", the assay examines the hair strand itself, not the follicle below 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.
