Hair Follicle Drug Testing - San Leanna, TX

What it is, How it works

Hair testing is increasingly recognized as a robust method for detecting drug and alcohol consumption. Hair captures a comprehensive history of alcohol and other drugs by trapping biomarkers within the growing hair strand’s fibers. When collected near the scalp, hair enables up to a 3-month detection period for alcohol and drugs. It's straightforward to collect, challenging to tamper with, and simple to ship.

A 1.5-inch segment of roughly 200 strands of hair (equivalent to a #2 pencil's diameter) nearest to the scalp yields 100mg of hair, the optimal sample for screening and verification. For EtG, add-ons, and/or tests beyond 10 panels, a specimen weight of 150mg is advisable. Use a jeweler’s scale to weigh the specimen. In cases where scalp hair isn’t available, a comparable quantity of body hair can be gathered. When we mention head hair, we specifically mean scalp hair alone. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial processing of a sample into a laboratory’s system. This process includes ensuring the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening offers a preliminary quick assessment for drugs of abuse. While Screening is a cost-efficient technique to exclude drug use in most samples, a positive screen must be verified to be legally acceptable. Any samples with presumptively positive Screening results necessitate subsequent confirmation.

If a sample appears to be positive during Screening, additional hair is drawn from the original specimen and prepared for Extraction. This phase extracts drugs from hair at a much lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The end-to-end laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can track drug use for up to 90 days, offering a longer detection period than urine tests.
• Difficulty to cheat: Cheating on a hair drug test is quite challenging, which enhances result accuracy.
• Provides historical data: It reveals a history of drug usage over time, rather than only recent use.

Limitations:

• Cannot detect recent use: Drugs take about 5-7 days to become detectable in hair.
• Cost: Hair drug tests are typically more costly compared to other drug testing methods.
• Variations in results: Influences like hair color and individual hair growth rate can impact the drug metabolites' concentration within the hair.

Note: While frequently called "hair follicle tests", the test itself 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. 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.
