Hair Follicle Drug Testing - Lake Hallie, WI

What it is, How it works

Hair analysis is now regarded as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by securing biomarkers within the strands as they grow. When hair is collected near the scalp, it can potentially offer a detection timeframe of up to roughly three months for drugs and alcohol. Hair samples are straightforward to gather, relatively challenging to alter, and convenient for transportation.

A 1.5-inch hair sample consisting of roughly 200 strands (comparable in thickness to a #2 pencil) nearest to the scalp supplies 100mg of hair, which is the optimal quantity for both screening and validation. For specific tests like EtG, additional screenings, or tests exceeding 10 panels, 150mg of sample is advised. It's suggested to measure the specimen with a jeweler’s scale. If scalp hair cannot be obtained, an equal volume of body hair may be used. "Head hair" specifically means scalp hair, whereas "body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for drug testing consists of four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial phase of incorporating a sample into the laboratory's system. This step ensures that the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data entry absent in an electronic chain of custody system.

Screening serves as an initial scan for substance abuse. Though Screening is an economical approach to negate drug use in most samples, any positive screen result must undergo confirmation to be court-acceptable. Samples testing presumptively positive in Screening mandate a follow-up confirmation.

Should a sample demonstrate a presumptive positive in the Screening phase, more hair is retrieved from the original sample for the Extraction stage. Here, drugs are withdrawn from hair at concentrations much lower than other methods (e.g., urine or oral fluid), highlighting why hair drug screening is notably challenging.

Confirmation of any positive Screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a washing process prior to confirmation if necessary. The complete laboratory sequence from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair accreditation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can uncover drug use for up to 90 days, whereas urine tests offer a more limited detection window.
• Resistance to falsification: The difficulty of falsifying a hair drug test enhances result integrity.
• Chronological data provision: It presents a pattern of drug use over time, as opposed to just recent use.

Limitations:

• Inability to detect recent use: A period of 5-7 days is necessary for drugs to become traceable in hair.
• Expense: Hair drug tests tend to be more costly compared to other testing methods.
• Result variability: Variations such as hair color and personal hair growth differences can impact the concentration of drug metabolites in hair.

Note: Although often termed "hair follicle tests," the examination actually involves 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.
