Hair Follicle Drug Testing - Kelly, LA

What it is, How it works

Hair analysis is recognized as an effective means for detecting substance use. Hair retains a historical record of alcohol and drug usage by embedding biomarkers within its fibers. When gathered near the scalp, hair can offer an approximate 3-month detection window for substances. The collection process is straightforward, it's relatively tamper-resistant, and shipping is uncomplicated.

A sample measuring 1.5 inches, consisting of around 200 hair strands (roughly the thickness of a #2 pencil), is ideal and provides 100mg of hair, suitable for screening and confirmation purposes. For tests such as EtG, add-ons, or those above 10 panels, 150mg is recommended. It's advisable to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be utilized. "Head hair" refers exclusively to scalp hair, whereas "body hair" includes all other types (like facial, axillary, etc.).

Process Overview

The laboratory procedure for drug testing involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a specimen in the lab's system. This step confirms the sample is sealed and transported correctly, assigns it a random Laboratory Accessioning Number (LAN), and completes any additional data entry that an electronic chain of custody system does not provide.

Screening offers an initial assessment for drug abuse indications. As a cost-efficient measure, Screening can dismiss drug usage in most samples but requires confirmation of positive results for court admissibility. Any samples with a presumptive positive in Screening demand secondary confirmation.

When a specimen tests presumptively positive during Screening, additional hair is extracted from the initial sample to prepare for Extraction. Drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), highlighting the complexity of conducting hair drug screening.

Confirmation of positive screening results is accomplished using methods like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed based on necessity. The complete laboratory process, from Accessioning to Confirmation, is subject to scrutiny under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests can identify drug use for as long as 90 days, which is longer than urine tests.
• Challenge to falsify: It's very challenging to manipulate a hair drug test, thus enhancing result reliability.
• Provides a usage pattern: It offers a historical pattern of substance use over time, not just recent use.

Limitations:

• Lacks detection for recent usage: Drugs are detectable in hair approximately 5-7 days post-use.
• Higher cost: Hair drug tests tend to be costlier than alternative drug testing methods.
• Result variability: Factors like hair color and individual hair growth variance can influence drug metabolite concentrations in hair.

Note: Often labeled as "hair follicle tests," these tests actually analyze the hair strand itself, excluding the follicle under 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.
