Hair Follicle Drug Testing - Holton, KS

What it is, How it works

Hair analyses are increasingly recognized as an effective means of identifying drug and alcohol consumption. Hair captures long-term records of substances by embedding biomarkers within the hair strand's fibers. When cut near the scalp, hair samples can offer nearly a 3-month timeframe for detecting alcohol and drugs. Hair is easy to collect, relatively hard to tamper with, and simple to transport.

A 1.5-inch section consisting of around 200 strands (roughly the diameter of a #2 pencil) near the scalp yields 100mg of hair, considered an optimal sample for analysis and confirmation. For EtG, extra tests, and/or panels exceeding 10, 150mg of the sample is suggested. Utilizing a jeweler’s scale for specimen weighing is advisable. If scalp hair is not an option, a comparable amount of body hair can be used. When mentioning head hair, we solely refer to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The principal stages involved in a lab's drug test processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial handling of a sample in a laboratory setup. It verifies the sample was adequately sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and concludes any extra data entry absent from an electronic chain of custody system.

Screening comprises an initial brief examination for drugs of concern. While Screening is a cost-efficient approach to dismiss drug presence in most samples, any positive results must undergo confirmation to be legally valid. Presumptive positive samples in Screening necessitate subsequent confirmation.

If a sample is presumptively positive at the Screening phase, additional hair is taken from the initial sample for Extraction preparation. During this step, drugs are withdrawn from hair at markedly lower levels than other techniques (e.g., urine or oral fluids), underscoring why hair drug testing is notably complex to execute.

GC/MS, GC/MS/MS, or LC/MS/MS is employed for validating any positive screening outcomes. All presumptive positive samples undergo washing before confirmation as deemed necessary. The complete lab sequence from Accessioning through Confirmation operates under the CAP (College of American Pathologists) Hair guidelines and adheres to ISO / IEC 17025 standards for accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can reveal drug use for up to 90 days, surpassing the shorter detection periods of urine tests.
• Enhanced accuracy: Hair drug analysis is tough to deceive, enhancing result accuracy.
• Historical insights: It offers a timeline of drug usage over time, not solely recent consumption.

Limitations:

• Inability to identify recent use: Drugs become apparent in hair approximately after 5-7 days.
• Expense: Hair drug analyses generally incur higher costs than alternative drug testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite concentrations within the hair.

Note: Although frequently labeled as "hair follicle tests", the test examines the hair strand, not the hair 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.
