Hair Follicle Drug Testing - Talisheek, LA

What it is, How it works

Hair analysis stands out as an effective mechanism for identifying drug and alcohol consumption. The hair retains a prolonged history by embedding markers of alcohol and drugs within the fibers of the growing strands. When sampled close to the scalp, hair can reflect usage encompassing an interval of about three months for alcohol and drugs. It's easy to collect, hard to tamper with, and simple to transport.

A sample of 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil) nearest the scalp yields 100mg, optimal for both screening and confirmation. When testing for EtG, add-ons, or more than 10 panels, a sample of 150mg is advisable. Utilizing a jeweler’s scale for weighing the specimen is suggested. If scalp hair is not attainable, an equivalent volume of body hair can be obtained. Head hair specifically refers to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).

Process Overview

The core steps in the lab analysis of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning features the initial integration of a specimen into a lab's workflow, ensuring proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data input absent in an electronic chain of custody system.

Screening provides an initial examination for drug presence. Although Screening offers a cost-efficient approach to eliminate drug usage in most tests, a positive result needs affirmation to be admissible in court. Any presumptively positive samples in Screening necessitate secondary confirmation.

For presumptively positive samples in Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are isolated from hair at lower concentrations compared to other methods (ex. urine or oral fluid), making hair drug screening the most intricate methodology to execute.

Confirmation of a positive screening outcome is necessary via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleaned prior to confirmation as required. The full lab process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair classification and adherence to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection timeframe: Hair drug analysis identifies drug use up to 90 days, unlike urine tests that offer a shorter detection period.
• Hard to manipulate: Cheating on hair drug tests is challenging, assuring more reliable results.
• Delivers past usage data: It can indicate a pattern of drug habits over time, beyond recent use.

Challenges:

• Unable to detect immediate use: It generally takes 5-7 days for drugs to manifest in hair.
• Expense: Typically, hair drug testing costs exceed those of other methods.
• Result variations: Factors like hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests", the evaluation actually analyzes 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.
