Hair Follicle Drug Testing - Melbourne, IA

What it is, How it works

Hair testing is increasingly recognized as an effective means for detecting drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers within the fibers of the maturing hair strand. Hair gathered near the scalp can reveal up to nearly a 3-month timeframe for detecting alcohol and drugs. Hair is straightforward to collect, relatively resistant to tampering, and easy to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for screening and validation. For EtG, additional tests, and/or tests exceeding 10 panels, it is recommended to obtain 150mg of the sample. We advise using a jeweler’s scale to weigh the specimen. If scalp hair is unavailable, a similar quantity of body hair may be collected. When referring to head hair, we specifically mean scalp hair. Body hair refers to all other hair types (facial, axillary, etc.).

Process Overview

The central stages in the lab processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab’s system. This encompasses confirming the sample was securely sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional data not covered by an electronic chain of custody system.

Screening comprises an initial cursory inspection for drugs of abuse. Although Screening is a cost-efficient method for excluding drug use in most samples, a positive screen must be verified to be permissible in court. Any samples that test presumptively positive in Screening need further confirmation.

If a sample tests presumptively positive during Screening, additional hair is taken from the original specimen and readied for Extraction. At this phase, drugs are separated from the hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging methodology to perform.

Verification of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is reviewed per the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection duration: Hair drug tests can identify drug use for up to 90 days, unlike urine tests, which have a shorter detection span.
• Challenging to manipulate: It is notably difficult to deceive a hair drug test, enhancing result accuracy.
• Offers historical insights: It provides a usage pattern over time, not just recent use.

Limitations:

• Cannot identify recent use: It requires approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally cost more than alternative drug testing approaches.
• Result variability: Elements such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although commonly referred to as "hair follicle tests", the test actually assesses the hair strand and not the hair 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.
