Hair Follicle Drug Testing - Prairie Du Rocher, IL

What it is, How it works

Hair testing has become widely recognized as a significant method for uncovering drug and alcohol consumption. Hair captures a detailed history of alcohol and drugs by embedding biomarkers within the fibers of the developing hair strand. When retrieved near the scalp, hair can offer an estimated 3-month detection period for alcohol and drugs. Hair is straightforward to gather, somewhat challenging to tamper with, and convenient to send.

A 1.5-inch segment of roughly 200 strands of hair (similar to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for analysis and validation. For EtG, add-ons, and/or examinations beyond 10 panels, a 150mg specimen is advised. Using a jeweler’s scale to weigh the specimen is recommended. Should scalp hair be unavailable, an equivalent amount of body hair may be used. When discussing head hair, we mean only scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test outcome involves four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial processing of a specimen into a laboratory’s workflow. This process includes confirming that the specimen was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic chain of custody system.

Screening is an initial rapid assessment for drugs of abuse. Although Screening is an economical method to exclude drug use for most samples, a positive screen necessitates confirmation for court admissibility. Samples that are tentatively positive in Screening require additional confirmation.

If a sample is tentatively positive during Screening, more hair is extracted from the original specimen and prepared for Extraction. In this phase, drugs are extracted from hair at much lower levels than in other techniques (e.g., urine or oral fluid), which is why hair drug screening is the most challenging technique to execute.

Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples are washed before confirmation as needed. The entire laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to manipulate: It is exceedingly difficult to manipulate a hair drug test, enhancing result accuracy.
• Supplies historical insight: It can outline a pattern of drug use over time, rather than just recent activity.

Limitations:

• Incapable of detecting recent use: It typically takes 5-7 days before drugs are noticeable in hair.
• Expense: Hair drug tests tend to be costlier than other drug testing techniques.
• Inconsistencies in outcomes: Elements such as hair color and individual discrepancies in hair growth can influence the concentration of drug metabolites in the hair.

Note: Though commonly called "hair follicle tests", the test actually examines the hair strand rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing outperform traditional urine tests in Prairie du Rocher, IL?

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.
