Hair Follicle Drug Testing - Canaan, NH

What it is, How it works

Hair tests have gained recognition as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term recorder of alcohol and other drugs by capturing biomarkers in the fibers of the developing hair strand. When taken from near the scalp, hair can offer nearly a 3-month timeframe for detecting alcohol and other drugs. Hair is easy to collect, relatively hard to tamper with, and straightforward to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal amount for screening and validation. For tests like EtG, add-ons, and/or those above 10 panels, 150mg is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is unavailable, a comparable quantity of body hair may be used. When we mention head hair, it refers specifically to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory handling of a drug test result primarily involves four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the primary processing of a sample into a lab's system. This entails confirming that the sample was correctly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and performing any additional data entry lacking in an electronic chain of custody system.

Screening performs an initial rapid check for substances of abuse. While Screening serves as an economical way to discard drug use in most cases, a positive result requires confirmation for legal admissibility. Any samples that test presumptively positive in Screening need a secondary confirmation.

Should a sample show a presumptive positive in Screening, more hair is drawn from the initial sample and prepared for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging approach to execute.

Any positive results from screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug screening can recognize drug use for up to 90 days, outlasting urine tests which provide a shorter detection span.
• Difficulty to cheat: It is exceptionally challenging to deceive a hair drug test, ensuring more accurate results.
• Provides historical data: It can establish a pattern of drug use over time, not just recent consumption.

Limitations:

• Cannot detect recent use: It requires approximately 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests typically incur higher costs compared to other testing approaches.
• Variations in results: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Though often called "hair follicle tests", the analysis focuses on the hair strand rather than 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.
