Hair Follicle Drug Testing - Keokuk, IA

What it is, How it works

Hair analysis is increasingly recognized as an effective technique for identifying drug and alcohol consumption. Hair captures biomarkers within the strands of hair as it grows, reflecting a long-term history of substance use. When cut close to the head, hair can offer a detection period for alcohol and other drugs lasting up to around three months. This method is easy to administer, tamper-resistant, and simple to transport.

A sample measuring 1.5 inches and comprising about 200 hair strands (approximately the thickness of a #2 pencil) when taken close to the scalp yields 100mg, which is the optimal amount for testing and confirmation. For EtG, extra tests, and/or panels exceeding 10, a sample weighing 150mg is advised. It is suggested to weigh the sample with a jeweler’s balance. If hair from the scalp is not accessible, equivalent body hair may be collected. References to head hair imply specifically scalp hair. Body hair denotes other types such as facial or axillary hair, among others.

Process Overview

The process of laboratory analysis for a drug testing result consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the initial introduction of a sample into a lab's workflow. This step involves confirming the sample's proper sealing and transport, allocating a unique LAN (Laboratory Accessioning Number), and completing any further data entry not covered by a digital chain of custody protocol.

Screening provides a quick preliminary assessment for the presence of drugs. Although Screening is a cost-efficient method for negating drug use in most cases, a positive screen must be corroborated to be court-admissible. Samples that test presumptively positive during Screening require confirmation through an additional method.

Should a sample be marked presumptively positive in the Screening phase, additional hair is extracted from the initial sample for further testing. During this extraction, drugs are retrieved from hair in significantly finer concentrations compared to other methods (such as urine or saliva), making hair drug testing the most complex methodology to execute.

Confirmation for any positive results from the screen is done utilizing GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples flagged as presumptively positive must be cleaned. The entire procedure from Accessioning to Confirmation is inspected under both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 certification benchmarks.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage up to 90 days, unlike urine tests that cover a shorter timeframe.
• High resistance to falsification: Due to the complexity of cheating, hair drug test results are highly reliable.
• Historical usage patterns: This method reveals a timeline of drug use rather than just indicating recent consumption.

Limitations:

• Incapability to identify recent use: Detection of drugs in hair requires about 5-7 days post-consumption.
• Expense: In general, hair drug tests tend to incur higher costs compared to other testing methods.
• Result variability: Factors such as the natural color of hair and individual differences in hair growth can influence the level of drug metabolites in hair.

Note: While termed as "hair follicle tests", the focus is on the analysis of hair strands instead of examining the root underneath 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.
