Hair Follicle Drug Testing - Goshen, CA

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. Hair offers an extended record of alcohol and drug intake by capturing biomarkers within the fibers of the hair shaft as it grows. When hair is taken from near the scalp, it can reveal drug and alcohol use over a span of up to about 90 days. Hair is straightforward to gather, relatively resistant to tampering, and straightforward to transport.

A sample measuring 1.5 inches and comprising approximately 200 hair strands (roughly the width of a #2 pencil) from the scalp will provide 100mg of hair, the ideal amount for screening and confirmation. For EtG tests, additional tests, or panels exceeding 10, 150mg of the sample is recommended. It is advisable to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair can be collected. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other types of hair (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result is comprised of four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial intake of a sample into a laboratory’s database. This step ensures that the sample was securely sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any further data entry absent from an electronic chain of custody protocol.

Screening serves as a preliminary swift evaluation for drugs of abuse. While it provides a cost-efficient method to eliminate drug use in most samples, any positive findings from Screening must be confirmed to be legally admissible. Samples showing presumptive positive results in Screening need additional confirmation.

When a sample presents a presumptive positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. This step entails extracting drugs from the hair at significantly lower concentrations compared to other methods (for example, urine or oral fluid), underscoring the complexity of conducting hair drug screening.

The Confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo a washing process prior to Confirmation as necessary. The entire lab process, from Accessioning through to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests which offer a shorter detection period.
• Difficulty in deception: Cheating a hair drug test is exceedingly difficult, thus enhancing result accuracy.
• Provides a historical overview: It furnishes a pattern of drug consumption over time, not just recent activity.

Limitations:

• Inability to detect recent usage: Drugs become detectable in the hair after approximately 5-7 days.
• Higher cost: Hair drug tests typically incur higher costs than alternative drug testing methods.
• Result variability: Factors like hair color and individual hair growth patterns can influence the concentration of drug metabolites present in the hair.

Note: Despite being commonly termed "hair follicle tests", the analysis is conducted on the hair strand and not the follicle located 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.
