Hair Follicle Drug Testing - Conrad, IA

What it is, How it works

Hair analysis has become recognized as a potent instrument for detecting drug and alcohol consumption. It offers a prolonged history of substance use by capturing biomarkers within the fibers of the growing hair strand. When sourced near the scalp, hair can deliver a detection window of roughly up to 3 months for substances. It is straightforward to collect, relatively hard to tamper with, and simple to dispatch.

A sample length of 1.5 inches comprising approximately 200 strands (roughly the diameter of a #2 pencil) near the scalp will yield 100mg, the optimal sample size for screening and verification. For EtG, additional panels, or tests exceeding 10 panels, a 150mg specimen is advisable. We suggest measuring the specimen using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent amount of body hair may be collected. When referring to head hair, it pertains solely to scalp hair. Body hair refers to all other types (facial, axillary, etc.).

Process Overview

The four primary stages in a laboratory drug test process include Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the preliminary processing of a sample into the laboratory system. This process ensures the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry absent from an electronic chain of custody system.

Screening provides an initial rapid assessment for substances of abuse. Screening is a cost-effective approach to exclude drug usage in most cases; however, a positive screen must be verified to be legally acceptable. Any samples that test presumptively positive in Screening require further confirmation.

If a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. In this step, drugs are retrieved from hair at substantially lower concentrations compared to other methods (e.g., urine or oral fluids), making hair drug testing one of the most challenging methodologies.

Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo a wash prior to confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests that have a limited detection period.
• Cheating difficulty: Cheating a hair drug test is very challenging, enhancing result accuracy.
• Provides historical insights: It can show a pattern of drug use over an extended timeframe, not just recent use.

Limitations:

• Cannot detect recent use: It takes around 5-7 days for drugs to become traceable in hair.
• High cost: Hair drug tests generally incur higher expenses compared to other drug testing methods.
• Result variations: Differences in hair color and individual hair growth rates can influence the concentration of drug metabolites in hair.

Note: While commonly termed as "hair follicle tests", the analysis itself concentrates on 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.
