Hair Follicle Drug Testing - Deerfield, WI

What it is, How it works

Hair testing is viewed as an effective method for detecting drug and alcohol consumption. Hair strands capture biomarkers within their fibers, providing a prolonged history of substance use. When extracted near the scalp, hair can offer a detection period of up to 3 months for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.

A sample measuring 1.5 inches with around 200 hair strands (equivalent to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is ideal for screening and confirmation purposes. For EtG, additional tests, and/or tests beyond 10 panels, a specimen of 150mg is suggested. We advise using a jeweler’s scale to measure the specimen's weight. If scalp hair is lacking, a comparable quantity of body hair can be gathered. Head hair specifically refers to scalp hair, while body hair encompasses other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result includes four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial handling of a sample within a lab’s system. This step verifies the proper sealing and shipping of the sample, allocates a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent in an electronic chain of custody system.

Screening is a preliminary assessment for drugs. Although Screening is a cost-efficient means to rule out drug usage in most samples, any positive result must be confirmed for legal admissibility. Samples that yield a presumptively positive result during Screening require further verification.

Should a sample test presumptively positive during the Screening phase, additional hair is extracted from the specimen for the Extraction process. Here, drugs are isolated from the hair at notably lower concentrations compared to other methods (such as urine or oral fluid), highlighting the challenges of hair drug screening.

Confirmation of any positive screening outcomes is performed via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if necessary. The laboratory process, from Accessioning to Confirmation, is reviewed according to both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can reveal drug consumption over a span of up to 90 days, unlike urine tests which have a limited detection window.
• Hard to evade: Cheating a hair drug test is notably challenging, thus enhancing result accuracy.
• Shows historical drug usage: This method illustrates drug usage trends over time, not just recent usage.

Limitations:

• Inability to detect recent usage: A time frame of 5-7 days is required for drugs to become detectable in hair.
• Higher cost: Hair drug tests generally involve greater expenses compared to other testing methods.
• Result variations: Aspects such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Frequently dubbed as "hair follicle tests", the actual analysis targets the hair strand, 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.
