Hair Follicle Drug Testing - Desert View Highlands, CA

What it is, How it works

Hair analysis has gained recognition as a potent method for identifying substance and alcohol consumption. Hair retains a prolonged record of alcohol and drug use by embedding biomarkers within the hair's growing strands. When samples are taken near the scalp, they can reveal a detection window for substances lasting up to roughly three months. Collection is straightforward, hard to tamper with, and easy to transport.

A sample measuring 1.5 inches with roughly 200 hair strands (comparable to the diameter of a #2 pencil) taken at the scalp can yield 100mg of hair, the optimal quantity for testing and confirmation. For EtG, additional tests, and/or examinations exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample with a jeweler’s scale. If no scalp hair is present, a similar portion of body hair can be gathered. By head hair, we mean only scalp hair, while body hair includes all other forms (facial, axillary, etc.).

Process Overview

The laboratory drug test processing involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where a sample is incorporated into a lab's system. This encompasses ensuring the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any other data entry absent from an electronic chain of custody.

In the Screening phase, a rapid initial examination for illicit substances occurs. While Screening is a cost-efficient method to eliminate drug use in the bulk of samples, a positive result must be verified for court validity. Samples with presumptive positives from Screening necessitate secondary verification.

When a sample indicates a presumptive positive during Screening, additional hair from the initial sample undergoes preparation for Extraction. In this phase, substances are drawn from hair at a significantly reduced concentration compared to other techniques (e.g., urine or oral fluid), making hair drug screening the most intricate methodology.

Any positive screening outcomes are validated using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed ahead of confirmation as required. The entire lab process, from Accessioning to Confirmation, undergoes review under CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug usage spanning up to 90 days, in contrast to urine tests with shorter detection spans.
• Resistance to tampering: Dishonesty in hair drug tests is extremely challenging, ensuring higher accuracy.
• Historical usage data: They reveal patterns of substance consumption over time, not just recent activity.

Limitations:

• Inability to detect immediate use: It takes about 5-7 days before drugs become detectable in hair.
• Expense: Hair drug testing is often pricier than alternative testing techniques.
• Result inconsistencies: Factors like hair color and individual hair growth rates can influence the concentration of drug metabolites within hair.

Note: Commonly miscalled "hair follicle tests", the test actually 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.
