Hair Follicle Drug Testing - Santa Cruz, AZ

What it is, How it works

The use of hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair serves as an enduring record of substance use by embedding biomarkers within the strands of hair as they grow. When collected near the scalp, hair can offer a detection period of up to three months for substances like alcohol. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A sample consisting of 1.5 inches of hair (approximately 200 strands, similar to a #2 pencil in thickness) from near the scalp provides 100mg, which is the optimal quantity for both screening and verification. For tests such as EtG, add-ons, or beyond 10-panel, 150mg is advised. It's recommended to weigh the sample with a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair can be used. Reference to head hair specifically indicates scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning involves the initial integration of the sample into the laboratory's system, which encompasses checking that the sample was properly sealed and dispatched, assigning a Laboratory Accessioning Number (LAN) randomly, and completing any requisite data entry absent from an electronic chain of custody system.

Screening is a preliminary examination for substance abuse. Although screening is a cost-efficient method to eliminate drug use in most samples, a positive screen requires confirmation to hold up in a legal setting. Any samples marked presumptively positive during Screening necessitate secondary confirmation.

Should a sample test presumptively positive during Screening, additional hair from the original sample is prepared for Extraction. In this phase, drugs are extracted at concentrations much lower than other methods (e.g., urine or oral fluid), illustrating why hair drug screening is the most complex methodology to execute.

The confirmation of any positive screen result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Samples that test presumptively positive undergo washing prior to confirmation if required. The entire laboratory process, from Accessioning through Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair standards and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, whereas urine tests provide a shorter detection period.
• Resistance to manipulation: Hair drug tests are exceedingly challenging to rig, enhancing result accuracy.
• Historical insight: Offers a timeline of drug use, rather than pinpointing just recent use.

Limitations:

• Inefficient for recent use: Drugs become detectable in hair within 5-7 days post-consumption.
• Expense: Hair drug tests are typically pricier than alternative drug testing methods.
• Result variability: Factors like hair color and individual hair growth can influence drug metabolite concentrations.

Note: Although commonly called "hair follicle tests," the analysis focuses on the hair strand itself rather than the follicle under 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.
