Hair Follicle Drug Testing - Center Point, LA

What it is, How it works

Hair analysis has gained recognition as a potent means for detecting substance usage. Hair records a prolonged history of alcohol and drug presence by embedding biomarkers within its fibers as it grows. When sourced near the scalp, hair offers up to around a 3-month detection period for substances like alcohol. It is convenient to collect, challenging to tamper with, and straightforward to transport.

A 1.5-inch segment of roughly 200 hair strands (approximately the width of a #2 pencil) nearest the scalp yields 100mg of hair, an ideal quantity for both screening and confirmation. For EtG, supplementary tests, and/or panels beyond 10, a 150mg sample is advisable. It is recommended to measure the sample with a jeweler's scale. Should scalp hair be unavailable, an equivalent body hair quantity might be used. When mentioning head hair, it implies scalp hair exclusively. Body hair encompasses all alternate hair types (facial, axillary, etc.).

Process Overview

The key stages in lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary input of a specimen into a lab's system. This involves checking that the specimen was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any extra data input not covered by an electronic chain of custody system.

Screening entails an initial brief assessment for substance misuse. Though Screening is economical for negating drug use in most samples, a positive outcome necessitates confirmation for legal admissibility. Any samples that appear positive at Screening must undergo secondary confirmation.

If Screening shows a sample as potentially positive, additional hair is extracted from the initial sample for Extraction. In this stage, drugs are isolated from hair at much lower concentrations than in methods like urine or oral fluid, making hair drug analysis the most complex methodology.

Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing potential positivity are cleansed before confirmation as required. From Accessioning to Confirmation, the entire laboratory procedure undergoes scrutiny under both the CAP (College of American Pathologists) Hair standard and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can identify substance use for up to 90 days, unlike urine tests with a shorter detection period.
• Challenging to manipulate: Hair drug tests are hard to tamper with, resulting in more reliable outcomes.
• Offers historical insight: It reveals a usage pattern over time, rather than just recent use.

Limitations:

• Unable to detect recent usage: Drugs become traceable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests typically cost more than other substance testing methods.
• Result variations: Factors like hair color and personal hair growth differences can influence the drug metabolite concentration in hair.

Note: Commonly called "hair follicle tests", the test itself examines the hair strand rather than 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.
