Hair Follicle Drug Testing - Lake Bluff, IL

What it is, How it works

Hair evaluations have emerged as an effective means for identifying drug and alcohol consumption. Hair archives a prolonged history of alcohol and other substances by embedding biomarkers within the strands during growth. When procured near the scalp, it can offer a detection span of around 3 months for alcohol and drugs. The collection process for hair is straightforward, not easily altered, and convenient for transportation.

A sample of a 1.5-inch section comprising about 200 hair strands (comparable to a #2 pencil's width) taken nearest to the scalp provides 100mg of hair, which is the preferred quantity for both screening and verification. For EtG, additional tests, and/or panels exceeding 10, a specimen amount of 150mg is advised. It is suggested to measure the specimen using a jeweler’s scale. If scalp hair is inaccessible, an equal portion of body hair may be taken. "Head hair" references scalp hair only, while "body hair" denotes all other varieties (facial, axillary, etc.).

Process Overview

The laboratory procedure for obtaining a drug test result entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is concerned with the initial integration of a specimen into the laboratory's system. This encompasses verifying proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic chain of custody system.

Screening carries out an initial, efficient assessment for substance misuse. Though Screening is a low-cost option to exclude drug usage for most samples, a positive finding necessitates confirmation to be valid in legal proceedings. Samples that test presumptively positive during Screening must undergo further confirmation.

If Screening indicates a presumptive positive, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are retrieved from the hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), highlighting the complexity of performing hair drug screening.

Confirmation of positive results from screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The complete laboratory sequence from Accessioning to Confirmation adheres to the standards prescribed by both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal drug use up to 90 days, unlike urine tests which require a shorter window.
• Challenging to manipulate: It's highly challenging to evade detection with a hair test, enhancing result accuracy.
• Presents historical patterns: It unveils drug usage trends over time, not merely recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs become detectable in hair approximately after 5-7 days.
• Expense: Generally, hair tests cost more than alternative drug testing techniques.
• Result variability: Factors like hair color and individual hair growth rates can influence drug metabolite levels in hair.

Note: Although often called "hair follicle tests", the assessment examines the hair strand, not 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.
