Hair Follicle Drug Testing - Madrid, IA

What it is, How it works

Hair testing is now recognized as a robust method to identify drug and alcohol use. Hair encases a lasting record by embedding biomarkers in the strands as they grow. Collected near the scalp, hair can reveal alcohol and drug presence for about a 3-month span. Hair collection is straightforward, offers resistance to tampering, and is convenient to dispatch.

A 1.5-inch sample comprising around 200 hair strands (approximately matching the girth of a #2 pencil) cut closest to the scalp yields 100mg, the optimal quantity for analysis. For EtG, additional substances, and tests beyond 10 panels, 150mg is preferable. It is advisable to measure the sample with a jeweler’s scale. If no scalp hair is available, a comparable quantity of body hair can be obtained. “Head hair” pertains exclusively to scalp hair, while “body hair” covers other types (facial, axillary, etc.).

Process Overview

Essential laboratory steps for processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where a sample is integrated into a lab’s system. Processes include ensuring the sample’s proper seal and shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not part of an electronic chain of custody system.

Screening constitutes an initial swift examination for drugs of abuse. Although a cost-saving method to negate drug usage in most samples, a positive screening requires confirmation for legal acceptability. Samples that test presumptively positive in Screening must undergo secondary confirmation.

Presumptive positives from Screening lead to additional hair extraction from the initial sample for Extraction. In Extraction, drugs are drawn from hair at much lower concentrations compared to other methods (such as urine or oral fluid), presenting hair drug screening as a challenging methodology.

Confirmation of any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo necessary washing before confirmation. The complete lab process from Accessioning to Confirmation is conducted under CAP (College of American Pathologists) Hair designation and adheres to the accreditation of ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug tests can reveal drug consumption for up to 90 days, surpassing urine tests with shorter detection durations.
• Challenging to deceive: The difficulties in bypassing a hair drug test enhance result accuracy.
• Historical insight: It can demonstrate a drug use pattern over time, not solely recent consumption.

Limitations:

• Incapable of detecting recent use: Drugs typically become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests generally incur higher costs than alternative testing methods.
• Result variability: Differences such as hair color and individual growth variations can influence drug metabolite concentration in hair.

Note: Often labeled as "hair follicle tests", the analysis targets the hair strand, 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. 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.
