Hair Follicle Drug Testing - Menahga, MN

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair captures a timeline of substance use by embedding biomarkers within the hair shaft as it grows. When cut near the scalp, hair can reveal alcohol and drug presence for up to a 90-day period. Hair is straightforward to gather, relatively challenging to tamper with, and convenient to send for testing.

A 1.5-inch segment containing roughly 200 hairs (similar in size to a #2 pencil) nearest to the scalp, providing 100mg of hair, serves as the optimal sample for both screening and confirmation. For EtG, extensions, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It is suggested to measure the sample using a jeweler’s scale. If scalp hair is not accessible, a comparable amount of body hair might be used. References to head hair pertain only to scalp hair. Body hair includes all other hair types like facial or axillary hair.

Procedure Overview

The laboratory processing of a drug test encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage where a sample is introduced into the lab system. This step involves confirming that the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody system.

Screening offers an initial assessment to detect drug abuse. While cost-efficient, any positive results from Screening must be substantiated for legal admissibility. Samples with presumptive positive results in Screening necessitate a follow-up confirmation.

If a presumptive positive arises during Screening, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are isolated from the hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), rendering hair drug testing one of the most complex methodologies.

Positive screening outcomes are confirmed through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptive positive samples undergo washing as necessary. The complete laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair guidelines and complies with ISO / IEC 17025 accreditation.

Benefits of hair drug analysis:

• Extensive detection timeframe: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests with shorter detection periods.
• Challenging to deceive: Hair drug testing is notably difficult to tamper with, yielding more reliable results.
• Offers longitudinal data: It illustrates a pattern of drug use over time, not merely recent use.

Drawbacks:

• Inability to detect recent use: It takes about 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug testing is typically pricier than other drug testing modalities.
• Result variability: Elements like hair color and individual differences in hair growth can influence the presence of drug markers in hair.

Note: Although often termed as "hair follicle tests," the analysis involves the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Testing Prevails Over Urine Testing in Menahga, MN

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.
