Hair Follicle Drug Testing - Mitchell, IL

What it is, How it works

Hair testing is increasingly regarded as a robust instrument for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug intake by embedding biomarkers within the strands of growing hair. When collected near the scalp, hair can offer up to an approximately 3-month detection timeframe for alcohol and various drugs. Hair collection is straightforward, relatively challenging to tamper with, and easy to transport.

A hair sample measuring 1.5 inches, consisting of roughly 200 strands (akin to a #2 pencil's width), collected closest to the scalp, yields 100mg of hair, which is ideal for screening and confirmation. For tests such as EtG, add-ons, or those exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent amount of body hair may be gathered. In reference to head hair, we mean scalp hair exclusively. Body hair includes all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary incorporation of a sample into a laboratory's system. This involves ensuring that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not furnished by an electronic chain of custody system.

Screening provides an initial rapid assessment for drug abuse. While cost-efficient for ruling out drug usage in most samples, a positive screen must be confirmed for courtroom admissibility. Any samples deemed presumptively positive during Screening necessitate a confirmatory test.

When a sample shows a presumptive positive result in Screening, additional hair is taken from the initial sample and prepared for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology to execute.

Confirmation for any positive screening finding is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed as needed before confirmation. The entire process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for up to 90 days, whereas urine testing offers a shorter detection period.
• Challenging to deceive: Cheating a hair drug test is extremely difficult, enhancing the accuracy of results.
• Reveals usage history: It can show a drug use pattern over time, not just recent usage.

Limitations:

• Fails to detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests tend to be pricier than other drug testing methods.
• Result variance: Factors like hair color and individual growth differences can influence drug metabolite levels in hair.

Note: Though often termed "hair follicle tests," the analysis is conducted on the hair strand rather than the follicle under 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.
