Hair Follicle Drug Testing - Sedgewickville, MO

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair preserves an extended history of substances by capturing markers within the fibers of the growing strand. When taken near the scalp, this type of sample can offer almost a three-month detection period for substances. Hair collection is easy, hard to tamper with, and convenient to transport.

A sample cut close to the scalp, 1.5 inches long and with roughly 200 strands (equivalent to a #2 pencil in size), yields 100mg of hair, which is the right amount for both screening and verification. For EtG, add-ons, and tests requiring more than 10 panels, a sample weighing 150mg is advised. It is suggested to weigh the sample with a jeweler’s scale. In cases where scalp hair is absent, a same-sized batch of body hair can be used. The term head hair refers solely to scalp hair, whereas body hair includes other types (such as facial and axillary hair).

Process Overview

The drug testing laboratory process involves four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first stage where the sample is logged into the lab system. This entails checking that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any required data entry that wasn't included by an electronic chain of custody system.

Screening performs an initial check for drugs of abuse. While it's a cost-efficient means to rule out drug use in most samples, any positive result needs to be verified for court relevance. Any samples screening presumptive positive require a confirmatory test.

For any samples deemed presumptively positive during Screening, additional hair is taken from the initial sample for the Extraction stage. Here, substances are extracted from hair at reduced levels compared to other techniques (such as urine or oral fluid), showcasing why hair drug screenings are challenging to execute.

Confirmation of positive screening results employs GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing prior to confirmation if needed. Each step from Accessioning to Confirmation is inspected according to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter time frame.
• Hard to manipulate: Hair drug tests are difficult to deceive, thus ensuring accuracy in results.
• Tracks historical data: This testing offers a view of drug use patterns over time, not just recent activity.

Limitations:

• Incapable of detecting recent use: There is roughly a 5-7 day delay before drugs appear in hair.
• Expense: Hair drug tests typically cost more than other methods.
• Result variations: Drug metabolite levels in hair can be influenced by factors such as hair color and individual growth differences.

Note: The term "hair follicle test" is often used, but the analysis is actually conducted on the hair strand rather than the follicle itself.

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.
