Hair Follicle Drug Testing - Valmeyer, IL

What it is, How it works

Through its development, hair analysis has emerged as a significant method for identifying drug and alcohol consumption. Hair archives a prolonged record of alcohol and substances by embedding chemical markers in the strands of hair as they grow. Gathered near the scalp, hair can reveal a detection period of about three months for various substances. Collection is straightforward, alteration is challenging, and shipping is uncomplicated.

A 1.5-inch fragment comprising approximately 200 hair strands (comparable to a #2 pencil's girth) nearest the scalp supplies 100mg of hair, which is optimal for evaluation and validation. For EtG inclusions or assessments exceeding 10 panels, it is advisable to secure 150mg of the sample. Utilizing a jeweler’s scale for accuracy in weighing is suggested. Should head hair not be accessible, a similar quantity of body hair can serve as an alternative. When mentioning head hair, it is specific to scalp hair. Body hair encompasses all other types (e.g., facial, axillary).

Process Overview

There are four primary stages involved in the laboratory's handling of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the commencement phase, where a sample is integrated into the laboratory’s database. This step ensures the sample's seal and shipment are intact, assigns a unique LAN (Laboratory Accessioning Number), and fills in any supplemental data not captured by digital chain of custody mechanisms.

Screening is a preliminary assessment for drug presence. Although Screening is a budget-friendly method to exclude drug usage in most samples, legal admissibility requires positive screens to be confirmed. Presumptively positive samples in Screening necessitate additional confirmation steps.

Should a sample show presumptive positivity during Screening, additional hair is extracted from the primary sample to undergo Extraction. Here, drugs are isolated from hair at significantly lower levels compared to other techniques (like urine or saliva), contributing to the complexity of hair drug screening.

Confirmation of any suspected positive outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Each presumed positive sample is cleaned before confirmation, if necessary. From Accessioning through Confirmation, the laboratory protocol is subjected to scrutiny, aligned with the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug assessments can identify drug use reaching up to 90 days, unlike urine tests which cover shorter periods.
• Difficult to manipulate: Cheating a hair drug evaluation is extremely difficult, thus enhancing the precision of results.
• Offers historical insights: This method can reveal patterns of substance usage over a timeline, not merely recent activities.

Limitations:

• Inability to detect recent consumption: Drugs typically become noticeable in hair after a span of 5-7 days.
• Expense: Hair drug evaluations are generally costlier than alternative testing methods.
• Result variability: Elements like hair color and personal hair growth differences may influence drug metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", the procedure actually evaluates the strand of hair, 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. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
