Hair Follicle Drug Testing - Junction City, LA

What it is, How it works

The utilization of hair testing has gained recognition as an effective method to detect drug and alcohol consumption. Hair captures a comprehensive record of alcohol and drug intake by embedding biomarkers within the fibers of its developing strands. When harvested near the scalp, hair can reveal alcohol or drug consumption within roughly a 90-day window. Hair is easy to collect, relatively hard to tamper with, and straightforward to transport.

A sample consisting of 1.5 inches of approximately 200 hair strands (roughly resembling the thickness of a #2 pencil) closest to the scalp equates to 100mg, which is optimal for both screening and confirmation purposes. For tests involving EtG, additional panels, and/or those exceeding 10 panels, a 150mg specimen is preferable. Utilizing a jeweler’s scale to measure the sample is advised. Should scalp hair not be available, an equivalent amount of body hair may be obtained. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for drug test results comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample undergoes initial processing into the lab's system. This entails confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not included by an electronic chain of custody system.

Screening provides an initial rapid assessment for drug abuse. Although Screening is a cost-efficient strategy to exclude drug use in most samples, a positive result requires confirmation to be legally acceptable in court. Samples that test presumptively positive during Screening necessitate a secondary confirmation.

If Screening suggests a positive result, further hair is extracted from the original sample to prepare for Extraction. In this phase, drugs are isolated from hair at far lower concentrations than other techniques (e.g., urine or oral fluid), reinforcing hair drug screening as the most challenging methodology to execute.

Confirmation of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples are cleansed before confirmation as required. The whole process from Accessioning to Confirmation is audited per both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to three months, unlike urine tests which have a limited detection timeframe.
• Reduced probability of deceit: Hair drug testing is exceptionally challenging to compromise, making the findings more credible.
• Displays past usage: It offers a timeline of drug use over extended periods, not just recent consumption.

Limitations:

• Cannot identify current usage: Detection in hair requires approximately 5-7 days post-drug use.
• Expense: Hair drug tests are typically pricier than alternative testing methods.
• Result variability: Elements like hair color and growth differences across individuals can influence drug metabolite concentrations in hair.

Note: Despite often being called "hair follicle tests", the analysis focuses on 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.
