Hair Follicle Drug Testing - Carson, IA

What it is, How it works

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol usage. By capturing biomarkers within the fibers of the growing hair strand, hair provides an extensive historical record of substance use. Collecting hair close to the scalp can yield a detection window of around 3 months for substances. Hair collection is straightforward, relatively tamper-resistant, and simple to transport.

A 1.5-inch segment consisting of approximately 200 hair strands (similar in size to a #2 pencil) closest to the scalp provides 100mg, which is considered the ideal sample size for screening and confirmation procedures. However, for tests involving EtG, additional add-ons, or panels exceeding 10, a specimen size of 150mg is advised. It's best to use a jeweler’s scale to weigh the specimen. Should scalp hair be unavailable, a comparable quantity of body hair is acceptable. References to "head hair" denote exclusively scalp hair, whereas "body hair" encompasses all other hair types (such as facial or axillary).

Process Overview

The drug test laboratory procedure primarily involves four steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample undergoes initial processing within the laboratory's system. This process ensures that the sample was both sealed and shipped correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry not captured by an electronic chain of custody system.

Screening serves as an initial, rapid assessment for substance abuse. While cost-efficient, a positive Screening result must be verified to be legally admissible. Samples that test presumptively positive during Screening require a confirmatory follow-up.

If Screening yields a presumptive positive, additional hair is extracted from the original sample for the Extraction stage. Here, the concentration of drugs is extracted from the hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting why hair drug testing is considered more challenging.

Any positive Screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are washed prior to Confirmation as needed. The laboratory process from Accessioning to Confirmation is rigorously reviewed under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for up to 90 days, surpassing the shorter window of urine testing.
• Resistance to tampering: Cheating on a hair drug test is exceedingly challenging, thereby enhancing result accuracy.
• Historical insight: Provides a comprehensive pattern of substance usage over time, as opposed to merely recent usage.

Limitations:

• Inability to detect immediate past use: Detection of drugs in hair takes about 5-7 days.
• Higher costs: Generally, hair drug tests entail greater expense compared to other drug-testing methods.
• Result variability: Hair color and individual growth differences can influence drug metabolite levels in hair.

Note: While commonly termed "hair follicle tests", the analysis is conducted on the hair strand itself, 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.
