Hair Follicle Drug Testing - Cedar Rapids, IA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair strands retain a chronological record of alcohol and drugs by embedding biomarkers within the hair's structure. When collected near the scalp, hair can offer a detection window of up to around three months for alcohol and drug use. Collection is easy, tampering is relatively difficult, and transportation is straightforward.

A 1.5-inch section containing approximately 200 hair strands (akin to a #2 pencil's diameter) taken nearest to the scalp yields 100mg of hair—an optimal sample for both preliminary and confirmatory tests. For EtG, additional tests, and/or those above 10 panels, a 150mg specimen is advised. It is suggested to weigh the sample with a jeweler’s scale. Should scalp hair be unobtainable, an equivalent quantity of body hair may be used. References to head hair pertain solely to scalp hair, while body hair denotes all other types, including facial and axillary hair.

Process Overview

The lab handling of drug test outcomes involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of integrating a sample into a lab setting. This step ensures the sample's seal integrity and correct dispatch, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any extra data entry absent from an electronic chain of custody system.

Screening is a preliminary evaluation aimed at detecting drug use for abuse substances. While Screening offers a cost-effective method for excluding drug involvement in most samples, a positive result requires validation for legal acceptability. Samples with a presumptive positive result in Screening necessitate further verification.

If the Screening phase suggests a positive result, additional hair is extracted from the primary sample and readied for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), which renders hair drug testing the most challenging method to execute.

The Confirmation of a positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation if required. Review of the entire lab process from Accessioning through Confirmation is performed under both the CAP (College of American Pathologists) Hair categorization and the accreditation in alignment with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair tests can identify drug use over a span of up to 90 days, contrasting with the shorter window of urine tests.
• Cheating complexities: The high difficulty of interfering with hair drug tests enhances result accuracy.
• Chronological data provision: This method reveals drug use patterns over extended periods, beyond immediate use scenarios.

Limitations:

• Immediate use undetectable: It usually takes between 5-7 days for drugs to manifest in hair analysis.
• Expense: Hair drug testing tends to be pricier compared to alternative methods.
• Result variability: Elements such as hair color and individual hair growth differences can influence drug metabolite levels in the hair.

Note: The term "hair follicle tests" is a misnomer as the analysis concerns the hair strand itself and not the follicle below 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.
