Hair Follicle Drug Testing - Haven, WI

What it is, How it works

Hair analysis is recognized as an effective approach for identifying drug and alcohol use. It offers a long-term record of substance use by capturing biomarkers within the fibers of the hair strand as it grows. When hair is cut closely to the scalp, it can offer about a 3-month window for detecting alcohol and drugs. It is easy to collect, tough to tamper with, and straightforward to transport.

A sample measuring 1.5 inches with roughly 200 hair strands (comparable to a #2 pencil) near the scalp will yield 100mg of hair, an excellent amount for screening and verification. For tests involving EtG, additional panels, and/or tests exceeding 10 substances, it is advised to collect 150mg. Using a jeweler’s scale for weighing the specimen is suggested. If scalp hair cannot be obtained, the same amount of body hair can be utilized. Head hair refers exclusively to scalp hair. Body hair encompasses all other types (including facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the sample’s preliminary integration into the laboratory's system. This process confirms the sample’s proper sealing and dispatch, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry the electronic chain of custody system doesn’t cover.

Screening executes an initial assessment for drugs of abuse. This economical method can rule out drug consumption for the majority of samples, but any positive screening must undergo confirmation for legal admissibility. Samples that screen presumptively positive mandate secondary confirmation.

Should a sample return a presumptive positive result during Screening, additional hair is extracted from the initial sample for the Extraction phase. At this stage, drugs are extracted from hair at a much lower concentration compared to other techniques (such as urine or oral fluid), making hair drug analysis one of the most complex forms of testing.

GC/MS, GC/MS/MS, or LC/MS/MS conducts confirmation for any positive screening outcomes. Prior to confirmation, all presumptive positives undergo washing if necessary. The entire lab process from Accessioning through Confirmation adheres to both CAP (College of American Pathologists) Hair determination and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use as long as 90 days, unlike urine tests, which have shorter detection durations.
• Low tamper probability: It is exceedingly challenging to manipulate a hair drug test, enhancing result reliability.
• Reveals usage timeline: It outlines a drug use pattern over time, not just recent consumption.

Limitations:

• Lacks recent use detection: It requires roughly 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests generally cost more than other testing techniques.
• Result disparities: Elements like hair color and individual growth rates can impact drug metabolite concentration in the hair.

Note: Frequently termed as "hair follicle tests", this test examines 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
