Hair Follicle Drug Testing - Big Pool, MD

What it is, How it works

Hair testing has emerged as an effective instrument for identifying drug and alcohol usage. Hair captures a prolonged history of substance use by embedding biomarkers within the strands' fibers. When gathered close to the scalp, hair can offer a detection period of up to about three months for alcohol and drugs. Collecting hair is straightforward, relatively hard to tamper with, and convenient for shipping.

An optimal sample involves a 1.5-inch portion of roughly 200 hair strands (approximately the width of a #2 pencil) near the scalp, providing 100mg of hair ideal for screening and verification. For EtG, additional tests, and/or tests beyond 10 panels, a 150mg sample is suggested. Using a jeweler’s scale for weighing the hair sample is advisable. If scalp hair is lacking, a similar quantity of body hair may be used. 'Head hair' refers to scalp hair exclusively, while 'body hair' encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning is the initial phase where a sample is processed into the lab's system. This process checks that the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry not covered by an electronic chain of custody.

Screening offers an initial swift assessment for drugs of abuse. Though Screening is cost-efficient for excluding drug use in most samples, a positive result requires confirmation to be valid in legal settings. Presumptively positive samples during Screening necessitate subsequent confirmation.

In cases where Screening shows a presumptive positive, extra hair is taken from the original sample for Extraction. At this juncture, drugs are isolated from hair at considerably lower concentrations than with other methods (such as urine or oral fluids), highlighting the complexity of hair drug testing.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleaned as needed. The entire lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can identify drug use for up to 90 days, versus the shorter detection frame of urine tests.
• Resistance to cheating: Cheating on a hair drug test is very challenging, thus enhancing result accuracy.
• Historical insight: It can reveal a pattern of drug consumption over a duration, rather than just recent usage.

Limitations:

• Lacks recent use detection: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug evaluations tend to be pricier than other drug testing alternatives.
• Result variability: Elements like hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Triumphs Over Urine Testing in Big Pool, MD is clear: hair tests provide an extended detection window with high reliability. Unlike urine tests, hair follicle assessments can trace drug usage up to 90 days, giving a comprehensive history of substance intake.

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.
