Hair Follicle Drug Testing - Waterloo, AR

What it is, How it works

Hair testing is recognized as a significant resource for identifying the use of drugs and alcohol. Hair offers an extended timeline of drug and alcohol history by capturing biomarkers in the strands of hair as they grow. When taken from near the scalp, hair can indicate alcohol and other drug use for up to a 3-month period. It is easy to gather hair, challenging to tamper with, and straightforward to transport.

A sample measuring 1.5 inches containing roughly 200 hair strands (about the circumference of a #2 pencil) nearest to the scalp delivers 100mg of hair, which is the optimal sample quantity for both screening and confirming tests. For EtG, extended panels, or tests exceeding ten panels, a specimen weighing 150mg is ideal. We suggest utilizing a jeweler's scale to weigh the sample. If scalp hair cannot be obtained, a comparable quantity of body hair can be used. When discussing head hair, it is specifically scalp hair. Body hair includes all other types (such as facial, axillary, etc.).

Process Overview

The laboratory process for analyzing drug test results involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where a sample is entered into the lab's system. This process entails verifying the sample’s seal and shipment integrity, generating a random Laboratory Accessioning Number (LAN), and completing any supplementary data entry not covered by an electronic chain of custody process.

Screening is a preliminary test to identify drugs of abuse. Though Screening is economical for negating drug use in most samples, any positive result requires confirmation to be valid in legal contexts. Presumptive positives in Screening necessitate a further confirmation step.

If a sample tests presumptive positive during Screening, an additional portion of the original specimen is utilized for Extraction. This phase involves extracting drugs from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening more complex.

Confirmation of positives from Screening occurs via techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positive results are washed before confirmation as required. The comprehensive lab procedure from Accessioning through Confirmation receives oversight under both the CAP (College of American Pathologists) Hair designation and certification aligned with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal substance use up to 90 days back, unlike urine tests which offer a shorter detection timeframe.
• Reduced likelihood of cheating: Cheating on a hair drug test is quite difficult, which enhances the accuracy of results.
• Provides use history: It can map out a consumption pattern across months, as opposed to only recent intake.

Limitations:

• Inability to detect recent consumption: Detectable drug presence in hair takes roughly 5-7 days.
• Expense: Hair drug testing tends to be pricier compared to alternative testing methods.
• Result variability: Elements such as hair color and personal hair growth differences can impact drug metabolite concentration in hair.

Note: Though frequently termed "hair follicle tests," the analysis is conducted on 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.
