Hair Follicle Drug Testing - Eitzen, MN

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. Hair encapsulates a prolonged history of alcohol and illicit substances by capturing biomarkers within the strands as they grow. When harvested close to the scalp, it can offer almost a 3-month detection period for alcohol and drugs. Hair is straightforward to gather, not easy to tamper with, and convenient to send.

A hair sample measuring 1.5 inches consisting of approximately 200 strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, the optimal sample size for both screening and verification. For EtG, additional tests, and/or more extensive panels above 10, 150mg of the sample is advisable. We suggest using a jeweler’s scale to weigh the specimen. In the absence of scalp hair, a similar quantity of body hair can be obtained. The term "head hair" specifically refers to scalp hair. "Body hair" encompasses all other hair varieties (such as facial and axillary hair).

Process Overview

The laboratory analysis of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into the lab system. This process includes confirming that the sample was securely sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not fulfilled by an electronic chain of custody system.

Screening constitutes a preliminary rapid assessment for substances of misuse. Although Screening serves as a cost-efficient means to rule out drug usage across most samples, a positive result necessitates confirmation for legal admissibility. Samples with a presumptive positive result in Screening require secondary verification.

Should a sample display a presumptive positive outcome during the Screening phase, additional hair is extracted from the original sample for Preparation for Extraction. During this step, drugs are derived from the hair at concentrations lower than those in alternative methodologies (e.g., urine or saliva), establishing hair drug screening as the most challenging approach to conduct.

Verification of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing as required before confirmation. The comprehensive lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests with a shorter detection duration.
• Challenging to falsify: Hair drug tests are very hard to manipulate, ensuring more reliable results.
• Offers historical insights: It provides a pattern of drug usage over time, rather than just recent activity.

Limitations:

• Incapable of detecting recent intake: It requires about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests tend to be pricier than alternative drug testing techniques.
• Result variability: Elements like hair color and personal variations in hair growth influence the concentration of drug metabolites detectable in hair.

Note: Although often termed "hair follicle tests", the analysis targets the hair strand itself, 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.
