Hair Follicle Drug Testing - Vidal, CA

What it is, How it works

Hair testing is recognized as an effective means for detecting drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug use by embedding biomarkers in the strands of hair as they grow. When collected near the scalp, hair can reveal drug and alcohol use for up to around three months. It is straightforward to collect, relatively hard to tamper with, and easy to send.

A hair sample measuring 1.5 inches and consisting of approximately 200 strands (similar to a #2 pencil's thickness) closest to the scalp offers 100mg of hair, the recommended amount for both screening and verification. For EtG, supplemental tests, or tests exceeding 10 panels, 150mg of hair is advised. It is suggested to use a jeweler’s scale to weigh the sample. If scalp hair isn’t available, an equivalent amount of body hair can be used. “Head hair” is referred to specifically as scalp hair. The term "Body hair" applies to other types of hair (like facial, axillary, etc.).

Process Overview

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

Accessioning is the first step where the sample is processed into a lab’s system. It involves ensuring the sample is properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing additional data entry tasks not provided electronically.

Screening acts as a preliminary check for illicit drug use. While it is a cost-efficient method for most samples to determine drug usage, results showing positive must be confirmed to be valid in legal contexts. Samples with presumptive positives undergo secondary confirmation.

For a presumptive positive during Screening, extra hair is taken from the initial sample for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than other tests (e.g., urine or oral fluid), demonstrating the complexity of hair drug screening.

Any positive found in the screening process is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a cleaning process before confirmation if required. The entire lab routine from Accessioning through Confirmation is evaluated based on both the CAP (College of American Pathologists) Hair category and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests detect drug presence for up to 90 days, whereas urine tests have a shorter timeframe.
• High resistance to subversion: It is challenging to manipulate a hair drug test, thus ensuring more precise outcomes.
• Chronological data availability: Offers data on drug use patterns over time, beyond just recent usage.

Limitations:

• Incapacity to detect immediate use: Detection in hair takes about 5-7 days post initial drug use.
• Expense: Hair drug tests tend to be pricier than other methods.
• Result variability: Hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: The term "hair follicle tests" is commonly used, but the analysis actually involves the hair strand, 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.
