Hair Follicle Drug Testing - Homer, LA

What it is, How it works

The use of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of such substance intake by embedding biomarkers within the strands as they grow. When collected near the scalp, hair can show drug and alcohol use over an estimated 3-month period. This type of sample is straightforward to collect, fairly resistant to tampering, and simple to transport.

Collecting a 1.5-inch segment comprising around 200 hair strands (similar in thickness to a #2 pencil) from the scalp area yields approximately 100mg of hair, which is the preferred amount for testing and confirmation. For EtG tests, extensions, and/or tests exceeding 10 panels, a specimen amount of 150mg is advised. Using a jeweler’s scale to measure the specimen is suggested. If a person lacks scalp hair, a similar quantity of body hair can be used. When specifying head hair, we mean scalp hair solely. Body hair covers all other types such as facial or axillary hair.

Process Overview

There are four primary steps in processing a drug test result in a laboratory: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step where a sample is initially processed into the lab system. This involves confirming that the sample was correctly sealed and transported, providing a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent in an electronic chain of custody setup.

Screening entails a quick preliminary assessment for substances of abuse. Although Screening provides a cost-efficient approach to exclude drug consumption for most samples, a positive screen must undergo confirmation to be deemed valid in legal contexts. Any samples identified as presumptively positive during Screening require further confirmation through a secondary test.

If a sample appears positive during the Screening process, additional hair is extracted from the initial sample for further preparation during Extraction. This phase sees drugs being extracted from hair at concentrations lower than those found in other testing methods, such as urine or oral fluid. Hence, hair drug testing is regarded as the most complex methodology to execute.

Positive screening outcomes are validated via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing as necessary before confirmation. Each step from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter timeframe.
• Hard to manipulate: Cheating a hair drug test is very challenging, making results more reliable.
• Provides patterns of usage: It reveals drug usage trends over time rather than just recent use.

Limitations:

• Cannot detect recent consumption: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug testing is typically pricier than other testing methods.
• Result variability: Factors such as hair color and differences in individual hair growth can influence the concentration of drug metabolites in hair.

Note: Though commonly termed as "hair follicle tests", the analysis is conducted on 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.
