Hair Follicle Drug Testing - Stockwell, IN

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair strands hold onto biomarkers within their fibers over time, offering an extended history of substance use. If cut near the scalp, hair can present a detection timeframe of up to around three months for alcohol and drugs. Collecting hair is straightforward, hard to tamper with, and easy to ship.

A 1.5-inch portion of roughly 200 hair strands (comparable in thickness to a #2 pencil) closest to the scalp provides 100mg of hair, the optimal amount for testing and verification. For EtG, special requests, or tests beyond 10 panels, a 150mg sample is advised. It's best to use a jeweler’s scale for weighing the sample. Should scalp hair be missing, a similar quantity of body hair is acceptable. "Head hair" specifically indicates scalp hair, while "body hair" encompasses all other types (e.g., facial, axillary).

Process Overview

The laboratory procedure of a drug test result consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the primary integration of a sample into a laboratory system. This incorporates ensuring the sample’s seal and shipment were correct, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data input absent from an electronic chain of custody system.

Screening involves a preliminary rapid assessment for drugs of abuse. Although Screening is an economical approach to rule out drug use in most samples, a positive result requires confirmation to be legally admissible. Samples presumed positive in Screening necessitate a secondary confirmation.

For samples presumptively positive in the Screening phase, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug screening a challenging procedure.

Confirmation of any presumptively positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation if necessary. The full laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests which have a shorter timeframe.
• Hard to cheat: It is notably challenging to falsify a hair drug test, leading to more reliable results.
• Historical insight: It can illustrate a pattern of drug use over time, rather than only recent use.

Limitations:

• Inability to identify immediate use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests generally incur higher costs than other testing techniques.
• Result variability: Aspects like hair color and individual hair growth can alter drug metabolite concentrations in hair samples.

Note: Often termed "hair follicle tests," the actual analysis targets 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. 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.
