Hair Follicle Drug Testing - Vincent, AL

What it is, How it works

The examination of hair has emerged as an effective approach for identifying drug and alcohol consumption. Hair captures a prolonged timeline of drug and alcohol use by embedding biomarkers within the growing hair shaft’s fibers. When gathered near the scalp, hair offers a detection window extending up to roughly three months for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.

A 1.5-inch segment containing around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is ideal for testing and confirmation. For EtG, additional tests, and tests beyond 10 panels, 150mg of the sample is advisable. We suggest measuring the sample weight on a jeweler’s scale. If scalp hair isn’t available, an equivalent amount of body hair may be used. By head hair, we refer exclusively to scalp hair. Body hair encompasses all other hair forms (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is first processed into the lab’s system. This phase ensures the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any supplemental data entry missing from an electronic chain of custody system.

Screening checks for drugs of abuse initially and swiftly. While Screening is a cost-efficient method to rule out drug usage in most samples, a positive screen requires confirmation to be valid in legal settings. Samples that indicate a presumptive positive in Screening mandate a secondary validation.

Should a sample show a presumptive positive during Screening, more hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than in other methods (such as urine or oral fluid), making hair drug screening the most challenging method to conduct.

Positive Screening outcomes undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Washing of all presumptive positive samples occurs before confirmation if necessary. The overall laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditations.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests, which offer a shorter window.
• Hard to falsify: Cheating a hair drug test is highly challenging, enhancing result accuracy.
• Historical insight: This method can outline a drug use pattern over time, not just recent usage.

Limitations:

• Cannot track recent use: It may take approximately 5-7 days for drugs to be noticeable in hair.
• Expense: Hair drug tests typically cost more than other testing techniques.
• Result variations: Elements like hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Although referred to as "hair follicle tests", the analysis actually involves the hair strand rather than 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.
