Hair Follicle Drug Testing - Starks, LA

What it is, How it works

Hair testing is widely recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the hair strand’s growing fibers. When taken near the scalp, hair samples can offer roughly a 3-month detection range for substances such as alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.

A 1.5-inch segment comprising approximately 200 hair strands (similar in size to a #2 pencil) closest to the scalp results in 100mg of hair, which is optimal for initial screening and subsequent validation. For EtG, add-ons, and/or tests exceeding 10 panels, it’s advisable to gather 150mg of hair. We suggest weighing the sample using a jeweler’s scale. If scalp hair isn’t accessible, a comparable amount of body hair could be utilized. When we mention head hair, it pertains solely to scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).

Process Overview

The key stages in processing a laboratory drug test result consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample within a laboratory framework. This step ensures the sample was appropriately sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and finalizes any missing data not incorporated via an electronic chain of custody system.

Screening involves a preliminary, rapid assessment for substance misuse. Though Screening is economical for dismissing drug use in most samples, a positive result necessitates additional verification to be defensible in legal settings. Samples yielding presumably positive results during Screening must undergo confirmatory testing.

If Screening indicates a presumptive positive, more hair is extracted from the initial sample and readied for Extraction. This phase involves withdrawing drugs from hair at much lower concentrations than other methods (such as urine or oral fluid), hence why hair drug testing is considered challenging.

Confirming any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if needed. The processing from Accessioning through to Confirmation is examined in accordance with the CAP (College of American Pathologists) Hair procedure and meets the ISO / IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, as opposed to urine tests which have a shorter detection span.
• Hard to deceive: It's extremely arduous to manipulate a hair drug test, resulting in more precise findings.
• Offers historical insight: It reveals a pattern of drug consumption over time, rather than merely current usage.

Limitations:

• Inability to identify recent use: Drugs take around 5-7 days to become detectable in hair.
• Price: Hair drug tests are typically pricier than alternative drug testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can influence the level of drug metabolites in hair.

Note: Although often termed as "hair follicle tests", the analysis actually examines 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.
