Hair Follicle Drug Testing - De Land, FL

What it is, How it works

Hair testing has increasingly been regarded as an effective means for detecting drug and alcohol use. Hair captures a long-term record of alcohol and drug ingestion by embedding biomarkers within the fibers of the hair as it grows. When taken from near the scalp, hair can reveal up to around a 3-month usage history for alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and easily transported.

A 1.5-inch hair sample comprising roughly 200 strands (about the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is ideal for analysis and verification. For EtG, additional tests, or those exceeding 10 panels, a 150mg specimen is advised. It's best to weigh the specimen using a jeweler's scale. If scalp hair is not accessible, a similar amount of body hair can be used. When mentioning head hair, we mean scalp hair specifically. Body hair refers to all other hair types (like facial, axillary, etc.).

Process Overview

The process of laboratory analysis for a drug test result consists of four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial reception and processing of a sample into the laboratory's system. This entails ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and entering any extra data that the electronic chain of custody system did not provide.

Screening involves an initial rapid assay for drugs of abuse. Though Screening is cost-effective for ruling out drug use in most samples, a positive screen requires confirmation to be valid in court. Any samples with a presumptive positive result in Screening require further confirmation.

Should a sample be presumptively positive in the Screening step, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than in other testing methods (such as urine or oral fluid), making hair drug testing one of the most challenging methods to perform.

Confirmation of any positive screen is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo necessary washing prior to confirmation. The complete laboratory processing from Accessioning to Confirmation undergoes review in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug testing can track drug use for up to 90 days, whereas urine testing offers a shorter detection window.
• Difficult to alter: Cheating on a hair drug test is highly challenging, ensuring more accurate results.
• Historical usage data: It provides an overview of drug usage patterns over time, rather than just recent usage.

Limitations:

• Limited recent use detection: Drugs take approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests", the test actually analyzes 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.
