Hair Follicle Drug Testing - Choctaw, OK

What it is, How it works

Hair analysis is increasingly recognized as an effective means for identifying substance use, offering a prolonged track of alcohol and drug consumption by locking biomarkers within the fibers of the expanding hair strand. When procured directly from the scalp region, hair can reveal consumption of alcohol and substances for as long as three months. Hair sampling is straightforward, somewhat resistant to tampering, and easy to send for testing.

A sample measuring 1.5 inches long and consisting of around 200 hair strands (approximately equivalent to a #2 pencil) taken nearest the scalp provides about 100mg of hair, making it the optimal sample size for preliminary tests and verification. For EtG tests, additional tests, or those exceeding 10 panels, a 150mg sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, the same quantity of body hair may serve as an alternative. In contexts where head hair is mentioned, it specifically refers to scalp hair; body hair encompasses all other hair categories (such as facial and axillary hair).

Process Overview

The core procedures in laboratory handling of a drug screening outcome encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the introductory handling of a sample within a laboratory’s framework, confirming the sample's seal and correct shipment, assigning it a random LAN (Laboratory Accessioning Number), and filling out any required data absent from an electronic chain of custody system.

Screening conducts a swift preliminary examination for substances of abuse. Though economical for eliminating drug usage in the majority of samples, a positive screening outcome necessitates confirmation for legal admissibility. Samples giving a preliminary positive result in Screening demand an additional verification test.

For samples returning a presumptive positive at the Screening phase, additional hair is gathered from the initial sample for Extraction. In this phase, drugs are isolated from hair at a much lower concentration compared to alternative methods (i.e., urine or oral fluid), underscoring the complexity of performing hair drug analysis.

Any positive outcome at the screening stage is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptively positive samples undergo cleansing as required. The comprehensive laboratory process from Accessioning to Confirmation undergoes scrutiny per both the CAP (College of American Pathologists) Hair specification and the ISO / IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug consumption for up to 90 days, unlike urine testing which offers a more limited detection span.
• Low likelihood of deception: Attempting to deceive a hair drug test is highly challenging, enhancing result reliability.
• Historic usage information: It outlines a pattern of drug use over time, beyond recent usage.

Limitations:

• Failure to detect recent use: Drugs become noticeable in hair about 5-7 days post-consumption.
• Expense: Hair drug tests tend to be costlier than alternative drug testing strategies.
• Result variability: Factors like hair color and individual hair growth differences may influence the dissemination of drug metabolites in hair.

Note: Frequently termed as "hair follicle tests", these tests evaluate the hair strand, not the rooted hair 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.
