Hair Follicle Drug Testing - Colfax, NM

What it is, How it works

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair provides a long-term record of alcohol and drug use by embedding biomarkers within the fibers of the strand as it grows. When hair is cut close to the scalp, it can offer up to a 3-month window for detecting alcohol and drugs. Hair is straightforward to collect, hard to tamper with, and convenient to transport.

A 1.5-inch sample of around 200 strands (comparable to a #2 pencil in width) from just above the scalp yields approximately 100mg of hair, which is ideal for both screening and confirmation. For EtG, add-ons, or tests beyond 10 panels, a 150mg sample is suggested. The specimen should be weighed using a jeweler’s scale. If scalp hair can't be collected, an equivalent amount of body hair is an alternative. "Head hair" specifically denotes scalp hair, while "body hair" includes all other varieties (e.g., facial, axillary).

Process Overview

The lab processing of drug test results comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initially processing a sample into the lab's system, ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and executing any additional data input not automated by an electronic chain of custody system.

Screening is a preliminary test for drug abuse. While it is a cost-effective approach for the majority of samples, a positive result necessitates confirmation for legal admissibility. Samples with a presumptive positive outcome during Screening warrant further confirmation.

Should a sample test presumptively positive at the Screening stage, additional hair is taken from the initial specimen and prepared for Extraction. This stage involves extracting drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluids), making hair drug screening a challenging methodology.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The entire laboratory process, from Accessioning to Confirmation, is conducted in compliance with both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use for up to 90 days, unlike urine tests, which have a shorter detection timeframe.
• Hard to manipulate: Cheating a hair drug test is extremely challenging, ensuring greater accuracy in results.
• Offers usage history: It allows for the observation of drug usage patterns over time, rather than only detecting recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug tests tend to be pricier than other testing methods.
• Result variability: Factors like hair color and individual hair growth variations can affect drug metabolite concentrations.

Note: Commonly termed "hair follicle tests," these tests actually examine 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.
