Hair Follicle Drug Testing - Pendleton, CA

What it is, How it works

Hair examination is now recognized as a potent approach for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and various substances by embedding biomarkers within the fibers of the developing hair thread. When collected near the scalp, hair offers a detection timeframe of up to around 90 days for alcohol and different substances. Hair collection is easy, mildly challenging to tamper with, and straightforward to transport.

A 1.5-inch segment of about 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair, the optimal sample size for screening and verification. For EtG, additional tests, and/or assays exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair can be collected. When indicating head hair, we are referring solely to scalp hair. Body hair denotes all other hair varieties (facial, axillary, etc.).

Process Overview

The four key steps in processing a drug test result in the laboratory are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial handling of a sample into a lab's system. This process involves checking that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and filling any additional data entries that aren't available in an electronic chain of custody system.

Screening involves an initial rapid evaluation for drugs of abuse. Though Screening offers a cost-efficient means to rule out drug consumption for most samples, a positive screening result demands confirmation to be court-admissible. Samples that test preliminarily positive in Screening require further confirmation.

If a sample tests presumptively positive at the Screening stage, more hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are extracted from hair at a significantly reduced concentration compared to other methodologies (such as urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are preliminarily positive are cleansed before confirmation if necessary. The full laboratory procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the certification to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection timeframe: Hair drug tests can identify drug usage up to 90 days, compared to urine tests which have a briefer detection period.
• Hard to deceive: It is extremely challenging to falsify a hair drug test, enhancing result accuracy.
• Offers historical information: It can illustrate a pattern of drug usage over time, not merely recent consumption.

Limitations:

• Cannot identify recent consumption: It takes about 5-7 days for drugs to be detectable in hair.
• Expense: Hair drug tests are typically costlier than other drug testing techniques.
• Result variability: Factors like hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: While often termed as "hair follicle tests", the actual analysis is of the hair strand and 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.
