Hair Follicle Drug Testing - Prince George, VA

What it is, How it works

Hair examinations have emerged as an influential instrument for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by encapsulating biomarkers within the fiber strands as hair grows. When extracted near the scalp, hair can offer roughly a three-month span for detecting substances like alcohol and other drugs. Hair is straightforward to acquire, relatively immune to tampering, and convenient to transport.

A 1.5-inch segment comprising about 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the perfect sample for screening and confirmation. For EtG, additional tests, and/or examinations exceeding 10 panels, 150mg of the sample is advised. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair might be used. When discussing head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four primary stages in the laboratory procedure of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample into a lab's framework. This process incorporates verifying that the sample was correctly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any further data entry absent in an electronic chain of custody system.

Screening offers an initial rapid assessment for drug abuse. Although Screening is an economical method for excluding drug usage in the majority of samples, a positive indication necessitates validation to be permissible legally. Samples suggesting positive results in Screening necessitate a secondary confirmation.

If a sample indicates positivity during the Screening phase, additional hair is extracted from the original sample to prepare for Extraction. During this stage, drugs are extracted from hair at much lower concentrations than other techniques (e.g., urine or oral fluid), which is why hair drug screening is the most challenging technique to execute.

Confirmation of any positive indication from screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing prior to confirmation if necessary. The whole lab procedure from Accessioning to Confirmation is scrutinized under 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 analyses can identify drug usage for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Hard to tamper with: It is very challenging to manipulate a hair drug test, ensuring more reliable outcomes.
• Historical data provision: It can exhibit a drug use pattern over an extended period, not just recent consumption.

Limitations:

• Inability to detect recent usage: Drugs generally become detectable in hair after approximately 5-7 days.
• Expense: Hair drug analyses are typically pricier than other drug testing techniques.
• Result disparities: Variables like hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although commonly termed "hair follicle tests", the analysis is performed on the hair strand, 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.
