Hair Follicle Drug Testing - Ricketts, IA

What it is, How it works

Hair testing has gained recognition as an effective means for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering a lengthy history of alcohol and drug use. When trimmed close to the scalp, hair provides a detection window of up to roughly three months for alcohol and drugs. It is easy to collect, challenging to tamper with, and simple to mail.

A 1.5-inch sample totaling about 200 hair strands (comparable to a #2 pencil's width) nearest to the scalp can supply 100mg of hair, the perfect quantity for both screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample with a jeweler's scale. In the absence of scalp hair, a similar volume of body hair may be gathered. When mentioning head hair, we specifically mean scalp hair alone. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four essential phases in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the sample's initial processing into a laboratory system. This phase includes confirming the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody system.

Screening initiates with a quick drug abuse check. This is a cost-efficient method to eliminate drug usage for most samples, though a positive screen must be validated for court admissibility. Any samples with a presumptive positive from Screening must undergo a secondary confirmation.

Should a sample show presumptively positive during the Screening phase, additional hair is extracted from the sample for preparation in the Extraction process. In this phase, drugs are obtained from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology to execute.

Positive screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All presumptive positives are cleaned before needed confirmation. The comprehensive laboratory procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a more limited detection window.
• Difficulty to cheat: Cheating on a hair drug test is notably difficult, thereby ensuring more accurate results.
• Provides historical data: These tests can illustrate drug use patterns over time, beyond just recent use.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Cost: Generally, hair drug tests are pricier than other drug testing methods.
• Variations in results: Aspects like hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: Though commonly called "hair follicle tests", the examination focuses 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.

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.
