Hair Follicle Drug Testing - Homewood, IL

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair offers a lengthy record of alcohol and drug use by encasing biomarkers in the strands of growing hair. When collected near the scalp, hair can reveal drug and alcohol use over a period of up to three months. It is easy to collect, hard to tamper with, and convenient to transport.

A hair sample of 1.5 inches, consisting of approximately 200 strands (roughly the diameter of a #2 pencil) nearest to the scalp, is required to obtain 100mg of hair, the optimal sample for testing and validation. For tests involving EtG, extra substances, and/or more than 10 panels, a sample weighing 150mg is advised. The sample should be measured on a jeweler's scale. If scalp hair cannot be gathered, an equal volume of body hair can be used. "Head hair" specifically pertains to scalp hair, while "body hair" includes all other hair types (such as facial and axillary hair).

Process Overview

The core steps in analyzing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails initially integrating a sample into the lab’s system. This step ensures the sample has been correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and fills in any missing data not provided by an electronic chain of custody system.

Screening is a preliminary assessment to check for drug usage. While Screening is a cost-efficient method to exclude drug use in the majority of samples, to be legally valid, a positive screen must be confirmed. Any sample showing potential positives in Screening requires a subsequent validation.

If Screening indicates potential positivity, further hair is extracted from the initial sample and prepared for Extraction. At this stage, drugs are extracted from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening complex to conduct.

Validation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before validation as necessary. The complete lab procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug usage for up to 90 days, unlike urine tests which cover a shorter span.
• Difficult to deceive: Cheating a hair drug test is notably challenging, ensuring more reliable results.
• Historical insight: Offers a pattern of drug usage over time, not merely recent consumption.

Limitations:

• Inability to detect new usage: Drugs only become detectable in hair after about 5-7 days.
• Expense: Hair drug testing tends to be costlier than other methods of drug testing.
• Result variability: Factors like hair color and personal differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Although often termed as "hair follicle tests", the test targets 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.
