Hair Follicle Drug Testing - Cordova, TN

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drugs by embedding biomarkers within the fibers of the growing strand. Collected near the scalp, hair offers up to a 3-month window for detecting alcohol and drugs. It is straightforward to collect, relatively hard to doctor, and simple to ship.

A sample of 1.5 inches of approximately 200 hair strands (comparable to the size of a #2 pencil) closest to the scalp provides 100mg of hair, the optimal quantity for evaluation and validation. For EtG, add-ons, and/or tests surpassing 10 panels, a specimen weight of 150mg is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, an equivalent amount of body hair may be collected. By head hair, we mean scalp hair only. Body hair includes all other types of hair (facial, axillary, etc.).

Process Overview

The fundamental steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the initial processing of a sample into a lab’s system. It consists of verifying that the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any additional information that an electronic chain of custody system does not provide.

Screening involves an initial rapid examination for drugs of abuse. Although Screening is an economical way to exclude drug use in most samples, a positive result must be confirmed to be accepted in court. Any samples that show presumptive positivity in Screening necessitate a secondary confirmation.

If a sample indicates presumptive positivity during Screening, more hair is extracted from the initial specimen and prepared for Extraction. At this stage, drugs are isolated from hair at a much lower concentration than with other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies to execute.

Confirmation of any positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is reviewed based on both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Hard to cheat: It is very challenging to deceive a hair drug test, resulting in more accurate outcomes.
• Offers historical data: It demonstrates a pattern of drug usage over time, not just recent consumption.

Limitations:

• Limited ability to detect recent use: It requires about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are usually costlier than other drug testing approaches.
• Variability in results: Factors like hair color and individual hair growth can affect the concentration of drug metabolites in hair.

Note: Often called "hair follicle tests", the examination actually assesses 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.
