Hair Follicle Drug Testing - Waterford, CA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair provides an enduring record of alcohol and other substances by capturing biomarkers within the growing hair strand's fibers. When collected from near the scalp, hair can offer up to a roughly 3-month detection period for these substances. It is straightforward to collect, relatively hard to tamper with, and simple to send.

A 1.5-inch section comprising around 200 hair strands closest to the scalp provides 100mg of hair, the optimal amount for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg specimen is advised. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair can't be obtained, a comparable amount of body hair might be used. Referring to head hair denotes only scalp hair. Body hair covers all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a laboratory’s framework. This involves confirming the sample's seal and proper shipment, assigning an arbitrary LAN (Laboratory Accessioning Number), and finishing any extra data input absent in an electronic chain of custody system.

Screening comprises an initial rapid assessment for abused drugs. Although Screening is an economical method to exclude drug use in most samples, a positive result must be validated to be acceptable in court. Samples appearing positive in Screening require a subsequent confirmation.

If a sample tests presumptively positive at the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.

Confirmation for any positive screening is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, whereas urine tests offer a shorter detection timeframe.
• Challenges in deception: Cheating a hair drug test is notably challenging, enhancing the reliability of the results.
• Delivers historical data: It offers a pattern of drug use over time, beyond just recent usage.

Limitations:

• Not for detecting recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests typically cost more than other drug testing methods.
• Result variations: Elements such as hair color and individual differences in hair growth might influence the concentration of drug metabolites in hair.

Note: Even though often referred to as "hair follicle tests", the test assesses the hair strand instead of 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.
