Hair Follicle Drug Testing - Cresco, IA

What it is, How it works

Hair analysis has emerged as an effective mechanism to identify drug and alcohol consumption. Hair acts as a long-term record for alcohol and drugs by encapsulating biomarkers within the fiber of the hair as it grows. Hair sampled from close to the scalp can reveal drug and alcohol usage for approximately up to a 3-month duration. Hair collection is straightforward, relatively resistant to tampering, and convenient for shipping.

A 1.5-inch sample, comprising around 200 hair strands (comparable to the girth of a #2 pencil) from the scalp will provide 100mg of hair, optimal for screening and confirmation. For EtG, additional evaluations, and/or tests exceeding 10 panels, a 150mg specimen is advised. It is recommended to measure the weight of the specimen using a jeweler’s scale. If scalp hair is inaccessible, an equivalent portion of body hair can be utilized. When mentioning head hair, it strictly refers to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four primary steps in the laboratory analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial phase of incorporating a sample into a laboratory’s system. It includes confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening encompasses an initial rapid assessment for drugs of abuse. Although Screening is an economical method for excluding drug usage on most samples, a positive screen necessitates confirmation to be valid in court. Any specimens yielding presumptive positive results in Screening demand additional confirmation.

When a sample shows presumptive positivity during the Screening stage, more hair is extracted from the original specimen and made ready for Extraction. During this phase, drugs are retrieved from hair at concentrations significantly lower than other methods (e.g., urine or oral fluid), which accounts for the complexity of performing hair drug screening.

Verification of any positive screening outcome is executed using GC/MS, GC/MS/MS or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as required. The full laboratory process from Accessioning to Confirmation undergoes assessment under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Lengthened detection period: Hair drug assessments can identify drug consumption for as long as 90 days, contrary to urine tests which offer a shorter detection duration.
• Challenging to deceive: The difficulty in tricking a hair drug test enhances the precision of the results.
• Historical usage data: It yields a historical pattern of drug use spanning a timeframe, as opposed to only current use.

Limitations:

• Inability to spot recent use: Detectable drug levels in hair require about 5-7 days.
• Expense: Typically, hair drug assessments incur higher costs than alternative drug testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests," the examination focuses on analyzing 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. 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.
