Hair Follicle Drug Testing - Delhi, LA

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair offers an extended historical record of alcohol and other drugs by encasing biomarkers within the strands during growth. When sourced close to the scalp, hair can offer up to an approximate 3-month detection period for alcohol and various substances. Hair collection is straightforward, relatively tamper-proof, and simple to transport.

A 1.5-inch sample comprising about 200 hair strands (approximating the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is the preferred quantity for analysis and verification. For EtG, additional tests, or panels exceeding 10, 150mg is advisable. Using a jeweler’s scale to weigh the sample is suggested. Should scalp hair be unavailable, a similar quantity of body hair can be used. It's important to note that 'head hair' pertains exclusively to scalp hair, while 'body hair' encompasses all other hair types (facial, axillary, etc.).

Process Overview

The procedure for processing a drug test result in a laboratory consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase, where a sample is entered into the lab’s system. This involves confirming the sample’s proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any data entry omitted by an electronic chain of custody protocol.

Screening offers a preliminary assessment for substances of abuse. Although Screening is an economical means to rule out drug use in most cases, positively screened samples need confirmation for legal admissibility. Any samples preliminarily positive in Screening require additional validation.

In cases of preliminary positive results during Screening, additional hair is extracted from the initial specimen and prepared for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than those in other testing methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging method to execute.

Confirmation of positive screening outcomes is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with assumed positive results undergo washing prior to confirmation as necessary. The complete laboratory sequence from Accessioning to Confirmation is reviewed in accordance with both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption up to 90 days, whereas urine tests provide a shorter detection frame.
• Resistance to manipulation: Cheating a hair drug test is notably challenging, enhancing result reliability.
• Historical insight: It delivers a drug usage pattern over time, beyond just recent activity.

Limitations:

• Incapability for recent detection: Drugs become identifiable in hair roughly 5-7 days post-consumption.
• Expense: Hair drug tests generally incur higher costs compared to other methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in the hair.

Note: Although often termed "hair follicle tests", the procedure evaluates 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
