Hair Follicle Drug Testing - Cecilia, LA

What it is, How it works

Hair testing is recognized as an effective technique for identifying drug and alcohol consumption. The hair traps biomarkers within the strands, providing an extended history of alcohol and drugs. When gathered near the scalp, hair offers a detection window of up to 3 months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.

To obtain an ideal specimen for testing, collect a 1.5-inch piece containing about 200 hairs (equivalent to the width of a #2 pencil) from the scalp, yielding roughly 100mg of hair. For tests including EtG, additional tests, and those over 10 panels, 150mg is preferred. We suggest using a jeweler's scale for accuracy. If scalp hair isn't available, an equivalent amount of body hair can be used. When mentioning head hair, it pertains solely to scalp hair. Body hair denotes all other types (facial, axillary, etc.).

Process Overview

The primary stages in lab analysis of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample enters the lab system. This step verifies correct sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any data missing from an electronic chain of custody.

Screening provides a preliminary check for drug presence. Though cost-effective and able to rule out drug usage in many cases, positive screenings necessitate confirmation for legal acceptance. All presumptive positive screenings require further confirmation.

If a sample tests presumptively positive during Screening, more hair is extracted and prepared for the Extraction stage. Drugs are extracted from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening particularly challenging.

Confirmation of positive screens is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed before confirmation when needed. The process from Accessioning to Confirmation is reviewed according to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests detect drug use for up to 90 days, unlike urine tests with a shorter window.
• Hard to manipulate: The difficulty in tampering with hair tests ensures greater result accuracy.
• Tracks usage history: Offers insights into drug use patterns over time, not just recent consumption.

Limitations:

• No recent use detection: Drugs become detectable in hair after about 5-7 days.
• Expense: Generally costlier compared to other testing methods.
• Result variations: Factors like hair color and individual hair growth differences can influence metabolite concentration.

Note: Although termed "hair follicle tests", they analyze the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
