Hair Follicle Drug Testing - Mahomet, IL

What it is, How it works

The examination of hair has emerged as an influential method for identifying the consumption of drugs and alcohol. Hair provides an extended historical record due to the entrapment of biomarkers within the fibers of the hair as it grows. When taken from near the scalp, hair offers an approximate 90-day detection span for substances. Hair is easy to gather, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (roughly the width of a #2 pencil) closest to the scalp, yields 100mg of hair, the perfect quantity for analysis and verification. For tests involving EtG, additional elements, and panels exceeding ten, 150mg of the sample is advised. It is advisable to use a jeweler’s scale for weighing the specimen. If scalp hair is not available, a similar amount of body hair can be collected. When we mention head hair, it specifically refers to scalp hair, whereas body hair includes all other hair types (such as facial or axillary).

Process Overview

The drug test laboratory procedure includes four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a lab’s system. This process encompasses the verification that the sample was sealed and transported correctly, the allocation of a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry missing from an electronic chain of custody system.

Screening represents an initial preliminary assessment for substance misuse. Although Screening is a cost-efficient strategy to exclude substance use in most cases, a positive finding must be verified to be acceptable in legal scenarios. Samples deemed presumptively positive during Screening require additional verification.

Should a sample test presumptively positive during the Screening phase, more hair is extracted from the initial sample and readied for Extraction. In this phase, substances are withdrawn from hair at significantly lower concentrations compared to other approaches (such as urine or saliva), which demonstrates why hair drug testing is considered the most complex method.

The verification of a positive result from Screening is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before verification when necessary. The end-to-end laboratory process from Accessioning through Confirmation is inspected under the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can identify drug consumption for as long as 90 days, contrasting with urine tests which have a shorter detection period.
• Resistance to manipulation: It is notably hard to deceive a hair drug test, enhancing result reliability.
• Offers historical insight: It can deliver a pattern of drug use over an extended period, rather than only recent consumption.

Limitations:

• Inability to detect recent use: Drugs become traceable in hair approximately 5-7 days after use.
• Expense: Hair drug tests tend to be more costly than other drug testing techniques.
• Result variability: Individual factors like hair color and growth rate can influence drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", the analysis is conducted on the hair strand, not on 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.
