Hair Follicle Drug Testing - Hudson, IA

What it is, How it works

Hair examinations are now recognized as an effective method for identifying usage of alcohol and drugs. The strands of hair offer an extended timeline of drug and alcohol usage by capturing biomarkers within the hair's structure as it grows. When sampled from near the scalp, hair can yield detection results for alcohol and drugs over an approximately 3-month timeframe. Hair samples are effortless to gather, relatively resistant to tampering, and straightforward to transport.

Collecting a 1.5-inch piece, consisting of about 200 hair strands (comparable in size to a #2 pencil) closest to the scalp, provides 100mg of hair, the perfect amount for both screening and confirmation. For EtG, additional markers, or tests exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler’s scale for weighing the sample is suggested. If scalp hair cannot be obtained, a similar quantity of body hair is acceptable. Note that head hair refers exclusively to scalp hair, while body hair includes all other forms (facial, axillary, etc.).

Process Overview

The four fundamental steps of processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is first entered into a lab's system. This phase entails confirming that the sample was securely sealed and transported correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening is an initial, rapid evaluation for drugs of abuse. Though cost-effective for ruling out drug use in most samples, a positive screen must undergo confirmation to be legally defensible. Any samples with a presumptive positive in Screening require follow-up confirmation.

In cases where a sample is determined as presumptively positive during Screening, extra hair is retrieved from the original sample for preparation in the Extraction phase. Here, drugs are isolated from hair at notably lower concentrations than in other procedures (such as urine or saliva), making hair drug screening challenging to execute.

For any positive screening outcomes, Confirmation is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and adheres to ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug use up to 90 days, as opposed to the shorter period for urine tests.
• High resistance to manipulation: Hair drug tests are notably challenging to falsify, enhancing result accuracy.
• Reveals usage trends: It reflects a pattern of drug use over an extended period, not solely recent consumption.

Drawbacks:

• Inability to detect recent use: It typically takes 5-7 days for drugs to become evident in hair.
• Higher expenses: Hair drug tests are usually more costly than other testing methods.
• Result fluctuations: Elements like hair color and personal variations in hair growth can impact drug metabolite levels in hair.

Note: Commonly termed "hair follicle tests", this procedure assesses the hair shaft, not the follicle under the skin.

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.
