Hair Follicle Drug Testing - Zita, TX

What it is, How it works

Hair testing is regarded as an effective method for identifying drug and alcohol usage. It offers a comprehensive history of substance exposure by preserving biomarkers within the hair fiber as it grows. When extracted near the scalp, this method provides a detection timeframe of up to three months for drugs and alcohol. The process of hair collection is straightforward, relatively resistant to tampering, and convenient for shipping.

A hair sample measuring 1.5 inches, consisting of approximately 200 strands (similar in thickness to a #2 pencil), yields around 100mg, which is ideal for both screening and confirming results. For tests such as EtG, additional tests, or panels exceeding ten, a sample weighing 150mg is advisable. Utilizing a jeweler's scale for weighing the specimen is suggested. If scalp hair is not available, a similar quantity of body hair can be used. "Head hair" refers solely to scalp hair, while "body hair" covers all other types (such as facial and axillary hair).

Process Overview

Four essential procedures are involved in the laboratory analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample enters a lab's system. This involves checking for proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing necessary data entry not covered by an electronic chain of custody.

Screening provides a preliminary check for drug abuse. While this step is economical for excluding drug use in most samples, a confirmed positive result is necessary for legal acceptance. Presumptive positives in the Screening must undergo further confirmation.

Should a sample be presumptively positive in the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. In this process, substances are drawn from hair at concentrations much lower than methods like urine or oral fluid testing, highlighting the complexity of hair drug screening.

Confirmation of positive screening outcomes involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleansed before confirmation if needed. The complete laboratory workflow from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair guidelines and complies with ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Capable of identifying drug use up to 90 days, in contrast to the shorter timeframe of urine tests.
• Reduced tampering: Cheating a hair drug test is challenging, thus enhancing result accuracy.
• Chronic use data: It describes drug use patterns over time rather than recent usage alone.

Drawbacks:

• Recent use undetectable: Drugs become observable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be pricier than other testing methods.
• Result variability: Factors like hair color and individual hair growth rates can impact drug metabolite levels in hair.

Note: Though often termed as “hair follicle tests”, the analysis is conducted on the hair strand rather than 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.
