Hair Follicle Drug Testing - Carville, LA

What it is, How it works

Hair testing is esteemed as a robust mechanism for identifying drug and alcohol consumption. By trapping biomarkers within the strands, hair captures a prolonged history of substance usage. If collected near the scalp, hair can present about a three-month detection spectrum for alcohol and drug substances. It's easy to gather, not easily tampered with, and straightforward to transport.

A sample of 1.5 inches, roughly 200 strands (comparable to a #2 pencil) from the scalp, yields 100mg, the optimal amount for both screening and confirmation activities. For EtG, added tests, or panels surpassing 10, a specimen of 150mg is recommended. It's advised to weigh the specimen on a jeweler’s scale. When scalp hair is unattainable, a similar quantity of body hair can be taken. By head hair, we specify only scalp hair. Body hair encompasses other types (facial, axillary, etc.).

Process Overview

The laboratory process for analyzing drug tests follows four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning introduces the sample into the lab’s system by confirming proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entries absent from an electronic chain of custody system.

During Screening, the sample undergoes an initial check for drugs of abuse. This process is economically efficient to dismiss drug use for most samples; however, a positive result must be confirmed for legal admissibility. Presumptive positives in Screening necessitate a secondary confirmation.

Should Screening identify presumptive positivity, additional hair from the original sample is prepared for Extraction, where drugs are isolated from hair at a lower concentration than other methods (e.g., urine or oral fluid), thus presenting hair testing as a challenging method.

Confirmation of any positive results detected in Screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples yielding presumptive positives receive a preliminary wash prior to confirmation if required. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and standards accredited to ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection window: Hair testing can trace drug usage up to 90 days, standing in contrast to the narrower window of urine tests.
• Challenging to alter: A hair test is challenging to manipulate, enhancing result reliability.
• Yields historical insight: It reveals a usage pattern over time, not limited to recent consumption.

Limitations:

• Inability to detect recent usage: Drugs take around 5-7 days to become traceable in hair.
• Expense: Typically, hair drug tests are pricier compared to other methods.
• Result variability: Aspects like hair color and individual hair growth variations could influence drug metabolite concentration in hair.

Note: Though frequently termed as "hair follicle tests," the assessment focuses on the strand itself, not the follicle beneath 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.
