Hair Follicle Drug Testing - Sill, OK

What it is, How it works

Hair follicle analysis is gaining traction as a robust method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug intake by encapsulating biomarkers within the fibers of the developing hair shaft. When gathered near the scalp, hair can offer an approximate detection timeframe of three months for alcohol and drug usage. Hair is easy to harvest, somewhat resistant to tampering, and convenient for transportation.

A 1.5-inch segment of roughly 200 hair strands (about the thickness of a #2 pencil) near the scalp produces 100mg of hair, which is the optimal sample for testing and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It is suggested to measure the specimen using a jeweler's scale. If scalp hair is not accessible, an equivalent quantity of body hair can be gathered. When speaking of head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The principal stages in the laboratory workflow of a drug test evaluation are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the primary integration of a sample into a laboratory's system. This entails ensuring that the sample was appropriately sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.

Screening offers an initial rapid assessment for drug abuse. Although Screening is a cost-efficient strategy to eliminate drug usage for most samples, a positive screen must be validated to be permissible in legal settings. Samples that test tentatively positive during Screening necessitate subsequent confirmation.

Should a sample show tentative positivity in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. During this phase, drugs are extracted from hair with a notably lower concentration than other methods (e.g., urine or oral fluid), which is why hair drug screening is exceptionally challenging to perform.

Verification of any positive screen result is performed through GC/MS, GC/MS/MS or LC/MS/MS. All samples showing tentative positivity are sanitized prior to confirmation as required. The complete laboratory sequence from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug usage for up to 90 days, surpassing urine tests that have a shorter detection timeline.
• Resistant to deception: It is extraordinarily challenging to manipulate a hair drug test, enhancing result accuracy.
• Offers historical insight: It reveals a pattern of drug consumption over time, beyond just immediate usage.

Limitations:

• Unable to detect recent use: Drugs take approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests are typically more costly compared to alternate drug testing methods.
• Result variability: Factors such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Although often termed "hair follicle tests", the evaluation is conducted on the hair shaft and not on 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
