Hair Follicle Drug Testing - Berkeley, MO

What it is, How it works

Recognized as a robust method for spotting drug and alcohol usage, hair testing captures the long-term history of alcohol and other drugs by embedding biomarkers within the strands of growing hair. When procured near the scalp, hair offers a detection period of up to about three months for alcohol and other substances. Hair is straightforward to collect, challenging to tamper with, and uncomplicated to transport.

To gather an ideal specimen for analysis and verification, a sample measuring 1.5 inches consisting of roughly 200 strands of hair (comparable to a #2 pencil) closest to the scalp will yield 100mg, which is ideal. For EtG, additional tests, and/or screenings beyond 10 panels, a specimen of 150mg is advised. Utilizing a jeweler’s scale is suggested for weighing the sample. In cases where scalp hair is not present, a similar quantity of body hair is acceptable. References to head hair indicate only scalp hair. Conversely, body hair pertains to all other types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of drug test outcomes is broken down into four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial step of integrating a sample into a laboratory’s system. This process includes verifying the sample's sealing and shipment conditions, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any supplementary data entry not supplied by an electronic chain of custody framework.

Screening provides a preliminary rapid assessment for drugs of misuse. While Screening serves as a budget-friendly approach to negate drug consumption for most samples, court admissibility demands confirmation of any positive screen. Samples yielding a presumptive positive at the Screening stage necessitate further confirmation.

In cases where a sample receives a presumptive positive at the Screening stage, additional hair is extracted from the primary specimen for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), explaining why hair drug screening is the most challenging methodology.

Positive screening outcomes undergo confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, any presumptive positive samples receive washing as required. The entire lab process from Accessioning through to Confirmation undergoes review under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug testing can reveal drug usage for as long as 90 days, unlike urine tests, which offer a shorter detection period.
• Resistance to deceit: It is exceptionally tough to falsify the results of a hair drug test, therefore improving result reliability.
• Historical usage insight: It presents a pattern of drug consumption over time instead of solely recent use.

Limitations:

• Inability to detect recent use: Drugs require roughly 5-7 days post-use before becoming detectable in hair.
• Expense: Hair drug testing is typically pricier compared to other testing methods.
• Result variability: Elements like hair color and individual growth differences can influence drug metabolite concentration in hair.

Note: Commonly mentioned as "hair follicle tests," the analysis concentrates on the hair strand, excluding the hair 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.
