Hair Follicle Drug Testing - Antonia, LA

What it is, How it works

Hair testing is regarded as a substantial method for identifying drug and alcohol usage. Hair captures a long-term timeline of substance consumption by embedding biomarkers in the strands' fibers. When sampled near the scalp, hair can trace alcohol and drugs within up to a 3-month span. Hair is straightforward to collect, relatively resistant to tampering, and convenient for transport.

A sample of 1.5 inches consisting of about 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp is optimal, offering 100mg of hair for thorough analysis. For EtG, additional tests, and/or panels surpassing 10, a specimen of 150mg is advised. It is suggested to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, a comparable measure of body hair is acceptable. "Head hair" exclusively refers to scalp hair, while "body hair" encompasses all other variants (such as facial and axillary hair).

Process Overview

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

Accessioning is the preliminary procedure for integrating a sample into a lab’s framework. This entails confirming that the sample was properly sealed and dispatched, generating a unique LAN (Laboratory Accessioning Number), and filling in any additional data not captured by an electronic chain of custody setup.

Screening serves as an initial check for substances of misuse. Although Screening offers an economical approach to dismiss drug use in most cases, a positive finding necessitates confirmation for legal acceptance. Samples deemed presumptively positive during Screening must undergo an additional confirmation phase.

Should a sample indicate a presumptive positive outcome in Screening, further hair is extracted from the initial specimen for the Extraction phase. This step involves isolating drugs from hair at notably lower concentrations than alternative approaches (e.g., urine or oral fluid), illustrating the complexity of hair drug screening.

Confirmation for any positive outcome in screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo a cleansing process before confirmation as applicable. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug examinations can uncover drug use for up to 90 days, unlike urine tests which have a briefer detection period.
• Hard to falsify: It's exceedingly challenging to manipulate the outcomes of a hair drug test, ensuring more precise results.
• Yields historical insight: The test can reflect a drug usage trend over time, not merely recent use.

Limitations:

• Incapable of detecting recent usage: Drugs take roughly 5-7 days to become detectable in hair.
• Expensive: Hair drug tests generally incur higher costs in comparison to other testing methods.
• Result variability: Elements like hair color and differences in individual hair growth can sway the concentration of drug residues in hair.

Note: Despite being popularly termed as "hair follicle tests", the analysis actually focuses on the hair strand rather than the follicle itself under 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.
