Hair Follicle Drug Testing - Moonshine Hill, TX

What it is, How it works

Hair testing is increasingly recognized as a robust method for drug and alcohol detection. By trapping biomarkers within the fibers of the hair as it grows, hair offers a long-term account of drug and alcohol use. When sourced near the scalp, hair can offer roughly a 3-month detection period for substances. Collection of hair is straightforward, relatively hard to tamper with, and convenient to send.

A 1.5-inch sample with approximately 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or analyses exceeding 10 panels, a specimen of 150mg is suggested. We advise the use of a jeweler's scale for determining specimen weight. If scalp hair cannot be obtained, a similar quantity of body hair may be gathered. “Head hair” specifically refers to scalp hair. “Body hair” indicates other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test encompasses four main stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing within a laboratory's system. This process verifies the proper sealing and shipping of the sample, issues a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry not covered by an electronic chain of custody system.

Screening entails a preliminary evaluation for drugs of abuse. Screening is a cost-effective method to exclude drug usage in the majority of cases, but positive results must be validated for courtroom admissibility. Samples deemed positive during Screening require confirmatory testing.

When a sample is found presumptively positive in Screening, additional hair is extracted from the original sample and prepared for Extraction. At this stage, drugs are removed from the hair at a significantly lower concentration than with other methods (e.g., urine or oral fluid), making hair drug screening amongst the most challenging methodologies to execute.

To confirm any positive screening outcomes, GC/MS, GC/MS/MS, or LC/MS/MS is utilized. All samples with presumptive positive results are pre-washed before confirmation as necessary. The cumulative lab process from Accessioning through Confirmation undergoes a review under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests have the capability to detect drug usage up to 90 days, unlike urine tests which have a more limited detection timeframe.
• Cheating deterrence: Given the difficulty to deceive hair drug tests, the results are more reliable.
• Insight into drug history: It offers a chronological pattern of drug usage over time, beyond recent usage.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug testing tends to be pricier than alternative drug testing methods.
• Result variability: Elements such as hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Despite the common reference to "hair follicle tests," the test examines the hair strand rather than the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
