Hair Follicle Drug Testing - Arispe, IA

What it is, How it works

The detection of drug and alcohol use has been powerfully transformed by hair testing. As hair grows, it traps biomarkers within its strands, providing a long-term account of substance use. When sampled from near the scalp, hair can offer a detection window of up to about three months for drugs and alcohol. Collecting hair is straightforward, difficult to falsify, and easy to transport.

Securing a 1.5-inch segment of roughly 200 hair strands (comparable in thickness to a #2 pencil) close to the scalp yields 100mg of hair, the optimal amount for accurate screening and validation. For EtG extensions and/or tests exceeding 10 panels, 150mg of the specimen is advisable. We suggest using a jeweler's scale for precise measurement. If scalp hair is unavailable, equivalent amounts of body hair may be used. Here, head hair refers solely to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

Testing a drug sample in the lab follows four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the process of logging a sample into a laboratory system, which involves ensuring the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry that an electronic chain of custody system might lack.

Screening constitutes a preliminary rapid check for the presence of drugs of abuse. Although Screening is an economical method to rule out drug use in the majority of cases, a positive Screen must be confirmed for court admissibility. All samples that show presumptively positive results in Screening need a follow-up confirmation.

If a sample is found presumptively positive during Screening, additional hair is retrieved from the original sample to prepare for Extraction. Drugs are extracted at significantly lower concentrations from hair compared to other methods (such as urine or oral fluid), which explains the challenging nature of hair drug screening.

Confirming any positive Screening result is done using either GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives undergo necessary washing before Confirmation. The entire lab process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests detect substance use for up to 90 days, unlike urine tests with shorter detection periods.
• High resistance to tampering: Due to the difficulty of cheating a hair test, results tend to be more reliable.
• Captures a usage history: Hair tests can show drug use patterns over time, unlike tests that capture only recent usage.

Limitations:

• Cannot indicate recent use: Detection in hair takes about 5-7 days post-use for drugs to become noticeable.
• Cost: Compared to other methods, hair drug tests typically incur higher expenses.
• Result variations: Elements like hair color and personal differences in hair growth may impact the concentration of drug metabolites in hair.

Note: Although termed "hair follicle tests", the analysis targets the hair strand, not the follicle located 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.
