Hair Follicle Drug Testing - Rocky, OK

What it is, How it works

Hair testing is widely recognized as an effective means for identifying alcohol and drug use. It offers a prolonged record by securing biomarkers within the fibers of a growing hair strand. When harvested near the scalp, hair can indicate alcohol and drug usage for up to about 3 months. Collection is straightforward, tampering is somewhat challenging, and shipping is hassle-free.

A 1.5-inch segment of roughly 200 hairs (approximately the diameter of a #2 pencil) nearest the scalp provides 100mg, an optimal amount for both screening and verification. For EtG, extended panels, or tests beyond 10 panels, a 150mg sample is preferable. It is advisable to use a jeweler’s scale to measure the specimen. If scalp hair is not available, a similar quantity of body hair is acceptable. By "head hair," we specifically mean scalp hair. "Body hair" encompasses all other hair types, such as facial or axillary hair.

Process Overview

Drug test processing in a laboratory involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to integrating a sample into a lab’s system initially. This step entails ensuring the proper sealing and shipping of the sample, assigning it a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.

Screening represents an initial evaluation for drugs of abuse. Although it offers an economical way to negate drug use in most samples, a positive screen needs subsequent confirmation for court admissibility. Any presumptively positive screen necessitates further affirmation through confirmation.

Should Screening yield a presumptively positive result, additional hair is extracted from the original sample for the Extraction stage. Here, drugs are extracted at a concentration far lower than other methods (such as urine or oral fluid), making hair drug screening particularly challenging.

Verification of a positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing prior to confirmation, as needed. The laboratory process is meticulously reviewed from Accessioning through Confirmation, adhering to the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditations.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug use up to 90 days back, unlike the relatively brief detection period offered by urine tests.
• Resistance to tampering: Hair drug tests are difficult to alter, thereby enhancing accuracy.
• Historical patterning: These tests can trace drug use patterns over time, not solely recent activity.

Limitations:

• Inability to detect recent consumption: It typically requires 5-7 days for drugs to be discernible in hair.
• Expense: Hair drug tests often incur higher costs than other testing methodologies.
• Result variability: Differing factors like hair color and individual hair growth variations can alter drug metabolite concentrations in the hair.

Note: While often termed "hair follicle tests", these tests evaluate the hair strand itself, excluding 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.
