Hair Follicle Drug Testing - Rennert, NC

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair retains a detailed history of alcohol and drug intake by encapsulating biomarkers within the strands as it grows. When collected near the scalp, hair can offer up to around a 3-month timeframe for detecting alcohol and drugs. Hair is straightforward to gather, challenging to tamper with, and convenient to send.

A sample measuring 1.5 inches and consisting of around 200 hair strands (similar to the diameter of a #2 pencil) closest to the scalp yields 100mg, which is the optimal amount for both screening and confirmation. For tests involving EtG, additional substances, or over 10 panels, 150mg of sample is advisable. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn't available, a similar quantity of body hair can be used. Note that when mentioning head hair, we exclusively mean scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

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

Accessioning is the initial phase where a sample is integrated into a laboratory's system. This phase ensures the sample was appropriately sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry that the electronic chain of custody system does not cover.

Screening involves a preliminary rapid test for drug abuse. Although Screening is a cost-efficient method to eliminate drug use in most samples, a positive result must be confirmed to be legally acceptable. Samples showing a presumptive positive in Screening necessitate further confirmation.

Should a sample test presumptively positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are extracted from hair at significantly lower levels compared to other methods (like urine or oral fluid), making hair drug testing the most challenging methodology to execute.

Confirmation of any positive screening result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation, as necessary. The entire laboratory process from Accessioning to Confirmation is overseen following both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to circumvent: Cheating a hair drug test is challenging, thus ensuring more precise results.
• Offers historical insight: It presents a drug use trend over time, rather than just recent use.

Limitations:

• Incapable of detecting recent use: Drugs become traceable in hair approximately 5-7 days after use.
• Expense: Hair drug tests generally cost more than other testing techniques.
• Result variability: Elements such as hair color and personal hair growth differences can influence the amount of drug metabolites in the hair.

Note: Often referred to as "hair follicle tests", these assessments analyze the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Compared to urine tests, hair follicle testing offers superior benefits in Rennert, NC. The efficiency of hair testing outshines traditional methods due to its extensive detection period and difficulty to tamper with. While urine tests might only identify recent substance use, hair tests detect usage over months, providing a more comprehensive view of an individual's habits and ensuring reliable results.

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.
