Hair Follicle Drug Testing - Union City, MI

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the strands, hair offers an extended timeline of alcohol and drug usage. When gathered near the scalp, a hair sample can reveal up to roughly three months of alcohol and drug history. Hair collection is straightforward, fairly resistant to tampering, and convenient for shipping.

An optimal 1.5-inch section comprising about 200 hair strands (analogous to the thickness of a #2 pencil) near the scalp equates to 100mg of hair, perfect for testing and confirmation. For EtG, supplementary, and/or tests surpassing 10 panels, a sample weighing 150mg is advisable. We suggest weighing the sample using a jeweler’s scale. Absent scalp hair, an equivalent volume of body hair can be obtained. Head hair pertains exclusively to scalp hair. In contrast, body hair encompasses other types like facial or axillary.

Process Overview

The key procedures in processing a drug test outcome in the lab include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a specimen is initially processed into the lab system. This step ensures the sample's seal and shipment integrity, assigns a random LAN (Laboratory Accessioning Number), and fulfills any remaining data input not handled by an electronic custody chain.

Screening is a preliminary assessment for drugs of abuse. It is a cost-efficient method to exclude drug use in most specimens, yet a positive finding in Screening must be substantiated for court validity. Presumptive positives necessitate secondary verification.

Upon a presumptive positive result in Screening, additional hair is drawn from the original sample to be prepared for Extraction. At this phase, drugs are sourced from hair at concentrations markedly lower than other methods (e.g., urine or oral fluid), underscoring the challenge of hair drug analysis.

Verification of positive screening results utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before verification as necessary. The comprehensive lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests reveal drug consumption up to 90 days, unlike urine tests which cover a shorter period.
• Hard to manipulate: Cheating a hair drug test is nearly impossible, resulting in more dependable outcomes.
• Reveals usage patterns: It displays a timeline of drug use, rather than just recent usage.

Limitations:

• Unable to identify recent use: Drugs are not detectable in hair until approximately 5-7 days post-consumption.
• Expense: Generally, hair drug tests are pricier than other drug testing methods.
• Result variability: Factors like hair color and individual hair growth variance can influence drug metabolite concentration in hair.

Note: Though commonly termed "hair follicle tests," the test evaluates 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.
