Hair Follicle Drug Testing - Harlan, IA

What it is, How it works

Hair testing is increasingly recognized as a strong method for detecting drug and alcohol consumption. Hair captures long-term evidence of alcohol and other drug use by embedding biomarkers within the hair strand as it grows. When sampled close to the scalp, hair offers up to a roughly 3-month detection period for alcohol and drugs. Hair is straightforward to collect, not easily tampered with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (around the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is the perfect sample amount for both screening and confirmation. For EtG, additional analyses, and/or tests beyond 10 panels, 150mg of the specimen is suggested. Using a jeweler’s scale to weigh the specimen is advisable. If scalp hair cannot be collected, a comparable amount of body hair can be utilized. References to head hair specifically denote scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The laboratory process for producing a drug test result includes four key steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample undergoes initial processing within a laboratory’s system. This involves confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not covered by an electronic chain of custody system.

Screening entails an initial rapid assessment for substances of abuse. Although Screening is a cost-efficient method to rule out drug use for the majority of samples, a positive screen requires confirmation to be legally valid. Samples that yield a presumptive positive result in Screening need secondary confirmation.

When a sample is presumptively positive during Screening, additional hair is extracted from the original sample and readied for Extraction. In this stage, drugs are extracted at a considerably lower concentration than in other techniques (e.g., urine or oral fluid), positioning hair drug testing as among the most challenging methodologies to conduct.

Any positive screening result is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The complete laboratory operation from Accessioning to Confirmation is reviewed per both CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests which offer a shorter detection window.
• Difficulty to cheat: Cheating a hair drug test is extremely difficult, ensuring more accurate results.
• Provides historical data: It can outline a pattern of drug use over an extended timeframe, rather than just recent use.

Limitations:

• Cannot detect recent use: Detecting drugs in hair requires about 5-7 days.
• Cost: Generally, hair drug tests tend to be more costly compared to other drug testing methods.
• Variations in results: Influences such as hair color and personal differences in hair growth can alter the concentration of drug metabolites in the hair.

Note: Although often known as "hair follicle tests", the analysis concerns 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.

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.
