Hair Follicle Drug Testing - Crescent Mills, CA

What it is, How it works

Hair analysis is now recognized as an effective method for detecting drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use, embedding biomarkers within its growing strands. When taken near the scalp, hair offers an approximate 3-month detection period for alcohol and drugs. The collection process is straightforward, hard to tamper with, and easy to send.

A 1.5-inch portion consisting of around 200 hair strands (comparable to a #2 pencil) near the scalp yields 100mg of hair, which is the ideal sample for testing and confirmation. For EtG, additional tests, and tests beyond 10 panels, 150mg of sample is advised. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair isn’t accessible, an equivalent amount of body hair can be used. When mentioning head hair, it indicates only scalp hair. Body hair includes all other hair types (e.g., facial, axillary).

Process Overview

The entire laboratory drug testing process consists of Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step in integrating a sample into the lab's system. This step ensures the sample’s seal and shipment are intact, allocates a random LAN (Laboratory Accessioning Number), and finalizes any other data entries missing from the electronic chain of custody.

Screening involves a preliminary assessment for abusive substances. Though Screening is a budget-friendly option to exclude drug consumption in most samples, a positive screening outcome needs verification for legal admissibility. Samples with initial positive results in Screening require further confirmation.

Should a sample show initial positive results in the Screening phase, an extra amount of hair is taken from the original sample for Preparation. At this point, drugs are extracted from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug tests the toughest to conduct.

For confirmation of any initial positive results, tests like GC/MS, GC/MS/MS, or LC/MS/MS are utilized. Samples with preliminary positive outcomes are cleansed before confirmation where necessary. The entire lab procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation as well as ISO / IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use for up to 90 days, whereas urine tests detect for a shorter span.
• Resistance to manipulation: Manipulating a hair drug test is extremely challenging, assuring more precise outcomes.
• Provides usage trends: It gives a pattern of drug consumption over a duration, unlike detecting just recent intake.

Limitations:

• Cannot detect recent intake: It takes around 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests typically cost more than other testing techniques.
• Variability in outcomes: Aspects like hair color and individual hair growth variations can influence drug metabolite levels in hair.

Note: Often called "hair follicle tests", this test examines the hair strand, not the beneath scalp hair follicle.

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.
