Hair Follicle Drug Testing - Modest Town, VA

What it is, How it works

Hair assessments have gained recognition as an effective method for identifying alcohol and drug usage. Hair offers a prolonged account of substance consumption by capturing biomarkers in the strands of the hair as it grows. When samples are collected near the scalp, hair can offer a detection period for substances of about three months. It is straightforward to gather hair, fairly resistant to tampering, and convenient to transport.

A 1.5-inch portion of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp provides 100mg, which is the optimal amount for both primary screening and confirmation. For EtG, additional options, or tests with more than 10 panels, 150mg is the suggested sample mass. It's advisable to measure the sample using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be collected instead. When discussing head hair, it specifically refers to scalp hair, while body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a laboratory’s system. This step includes confirming that the sample was appropriately sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any ancillary data entry not provided by an electronic chain of custody system.

Screening is a preliminary rapid assessment for drug presence. While Screening is a cost-efficient method to rule out drug usage in most samples, any positive result needs confirmation for legal admissibility. Samples suspected of being positive during Screening necessitate secondary confirmation.

If a sample is deemed potentially positive in the Screening phase, additional hair is extracted from the original sample for Extraction preparation. During this stage, drugs are removed from the hair at significantly lower concentrations than seen in other testing methods (e.g., urine or oral fluid), which is why hair drug screening is considered the most complex to conduct.

Confirmation of any presumptive positive from Screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples showing presumptive positivity are cleansed before confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair classification and adheres to ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug use up to 90 days prior, while urine tests possess a much shorter detection period.
• Challenging to manipulate: Manipulating hair drug tests proves exceedingly difficult, enhancing result accuracy.
• Historical usage insight: It offers a chronological pattern of drug use rather than detecting only recent usage.

Limitations:

• Incapable of detecting very recent use: It typically takes 5-7 days for substances to become detectable in hair.
• Expense: Hair drug tests are generally costlier compared to alternative drug testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests," these tests actually analyze the hair strand, not the follicle under 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.
