Hair Follicle Drug Testing - Argyle, MO

What it is, How it works

Hair testing has gained recognition as an effective method for detecting drug and alcohol consumption. Hair captures biomarkers within the strands as it grows, offering a detailed view of alcohol and drug usage over an extended period. When collected near the scalp, hair allows for a detection window of up to around 3 months for alcohol and drugs. Hair is easy to collect, not easily tampered with, and simple to transport.

For an optimal screening and confirmation, a 1.5-inch segment from about 200 hair strands (approximately the thickness of a #2 pencil) close to the scalp is required for a 100mg sample. For EtG tests, add-ons, and tests exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale for weighing is suggested. If scalp hair isn’t available, an equivalent amount of body hair can be gathered. "Head hair" specifies scalp hair exclusively, while "body hair" encompasses all other hair types (e.g., facial, axillary).

Process Overview

The laboratory processing for a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial introduction of a sample into a lab’s system, including verifying that the sample is sealed and shipped correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing additional data entry not captured by an electronic chain of custody.

Screening provides a quick preliminary check for substances. Though cost-effective for ruling out drug use in numerous samples, a positive screen requires confirmation to be court-admissible. Those samples that test positive in Screening need a subsequent confirmation.

If Screening results in a presumptive positive, additional hair is taken from the original sample for Extraction, where drugs are isolated from hair at lower concentrations compared to other methods (e.g., urine, oral fluid), making hair drug testing particularly challenging.

Positive Screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo washing prior to confirmation if necessary. The entire process from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug testing allows detection of drug use over a 90-day period, whereas urine tests offer a shorter detection timeframe.
• Difficulty to tamper: Tampering with hair drug test results is notably challenging, enhancing accuracy.
• Historical insight: The test reveals drug use patterns over time, not just recent consumption.

Limitations:

• Misses recent use: Drugs only become detectable in hair after approximately 5-7 days from usage.
• Expense: Hair drug tests generally incur higher costs than alternative testing methods.
• Result variability: Factors like hair color and growth individualities can influence drug metabolite concentrations in hair.

Note: Although referred to as "hair follicle tests," the actual analysis targets 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. 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.
