Hair Follicle Drug Testing - Meridian, CA

What it is, How it works

Hair analysis has emerged as a formidable method for identifying substance and alcohol consumption. The fibers of growing hair strands capture biomarkers, offering an extended historical record of alcohol and drug use. When hair is taken from the scalp, it provides an approximate 3-month detection period for substances and alcohol. Hair is straightforward to collect, less prone to tampering, and simple to transport.

A 1.5-inch segment comprising around 200 hair strands (approximately the size of a #2 pencil) near the scalp provides 100mg, which is the optimal quantity for testing and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. It is suggested to weigh the sample on a jeweler's scale. If scalp hair is missing, a comparable quantity of body hair may be used. When mentioning head hair, we mean scalp hair exclusively. Body hair denotes all remaining hair types (e.g., facial, axillary).

Process Overview

The laboratory workflow for processing a drug test involves four core stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary handling of a sample into a lab’s framework. This step ensures the sample's proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data input not covered by an electronic chain of custody mechanism.

Screening is a preliminary quick assessment for substance abuse. Though Screening is a cost-efficient approach to dismiss drug usage in most samples, a positive outcome necessitates confirmation for legal admissibility. Samples that register a presumptive positive in Screening mandate further confirmation.

If Screening indicates a presumptive positive, additional hair is obtained from the original sample for Extraction. In Extraction, substances are drawn from hair at a much reduced concentration compared to other methods (e.g., urine or oral fluid), rendering hair drug testing the most challenging method to execute.

GC/MS, GC/MS/MS, or LC/MS/MS is used to confirm any positive Screening results. All presumptive positive samples undergo washing prior to confirmation if required. The comprehensive lab workflow from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Extended detection period: Hair analysis can trace substance use for up to 90 days, unlike urine tests with a shorter detection span.
• Difficult to manipulate: It is notably challenging to manipulate a hair drug test, resulting in more precise outcomes.
• Delivers historical insights: It can reveal a substance usage pattern over a duration, not merely recent consumption.

Limitations:

• Incapacity to detect recent usage: Detection of substances in hair takes roughly 5-7 days.
• Expense: Hair drug testing is generally costlier than other testing techniques.
• Result discrepancies: Factors such as hair color and individual hair growth differences can influence the levels of drug metabolites in hair.

Note: Despite often being termed "hair follicle tests", the evaluation inspects the hair strand, not the sub-scalp hair follicle.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing offers significant advantages over traditional urine tests in Meridian, CA.

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.
