Hair Follicle Drug Testing - Ladonia, TX

What it is, How it works

Hair testing is now considered a robust method for detecting drug and alcohol usage. Hair captures a long-term usage history by storing biomarkers in its growing fibers. Collected near the scalp, hair samples can cover a detection period of up to 3 months for alcohol and other substances. Hair is easy to gather, quite challenging to tamper with, and straightforward to transport.

A sample of 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil in size) near the scalp provides around 100mg of hair, an ideal amount for both screening and confirmation. For expanded tests such as EtG, add-ons, and tests over 10 panels, a 150mg sample is advised. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair isn't available, an equal quantity of body hair may be gathered. When the term head hair is used, it refers specifically to scalar hair, whereas body hair encompasses all other hair types (e.g., facial, axillary).

Process Overview

The primary steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial sample processing into the lab's system. This procedure verifies the proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not covered by an electronic chain of custody system.

Screening performs a preliminary assessment for substances of abuse. Although cost-effective for ruling out drug usage in most samples, a positive screen must be confirmed for legal admissibility. Presumptively positive samples in Screening do necessitate a secondary confirmation.

Should a sample be presumptively positive during the Screening phase, additional hair is extracted from the initial specimen and prepared for Extraction. In this phase, substances are removed from hair at notably lower concentrations than in other techniques (e.g., urine or oral fluid), which explains why hair drug screening is the most challenging methodology.

Confirmation of any positive Screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if necessary. The entire lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which cover a shorter span.
• Hard to manipulate: Cheating a hair drug test is extremely difficult, thus ensuring more accurate outcomes.
• Offers historical insight: It presents a usage pattern over time, not just recent consumption.

Limitations:

• Inability to detect immediate use: Drugs require approximately 5-7 days to be detectable in hair.
• Expense: Hair drug tests are generally pricier than other testing methods.
• Result variability: Factors like hair color and personal variations in hair growth may affect drug metabolite concentrations in hair.

Note: Although often termed as "hair follicle tests," the test 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.
