Hair Follicle Drug Testing - Liberty, TX

What it is, How it works

Hair analysis has become regarded as an effective instrument for identifying drug and alcohol usage. It provides an extended record of alcohol and other substances by capturing biomarkers within the fibers of the growing hair strand. When gathered near the scalp, it offers up to roughly a 3-month detection window for both alcohol and other drugs. Hair collection is straightforward, somewhat challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches with approximately 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample size for initial screening and confirmation. For EtG, additional tests, and those exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler's scale is recommended for weighing the specimen. If scalp hair isn't present, an equivalent quantity of body hair can be gathered. When specifying head hair, we mean scalp hair specifically. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The principal steps in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into the laboratory's system. This process involves checking that the sample has been sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry that an electronic chain of custody system did not provide.

Screening is a preliminary check for drugs of abuse. Although Screening offers a cost-efficient method to eliminate drug usage in most samples, a positive screen must be confirmed to be admissible in legal contexts. Any samples presumed positive in Screening necessitate a subsequent confirmation.

Should a sample show a presumptive positive result during Screening, additional hair is retrieved from the initial specimen and readied for Extraction. In this phase, substances are extracted from hair at a substantially reduced concentration compared to other procedures (e.g., urine or oral fluid), which makes hair drug analysis the most challenging method to execute.

Confirmation of any positive Screening outcome is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples are washed before confirmation as required. The entire laboratory procedure, encompassing Accessioning to Confirmation, undergoes review in accordance with both the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests, which have a more limited detection period.
• Hard to manipulate: Cheating a hair drug test is very difficult, leading to more accurate outcomes.
• Provides historical insight: It can reveal a pattern of drug usage over time, not solely recent consumption.

Limitations:

• Unable to detect recent use: It requires approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally cost more than other drug testing methods.
• Result variability: Factors such as hair color and individual variations in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although often called "hair follicle tests," the test itself analyzes the hair strand and 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.
