Hair Follicle Drug Testing - Oyster Creek, TX

What it is, How it works

Hair is recognized as a potent means for detecting drug and alcohol consumption. It offers an extended historical view of substance use by capturing biomarkers in the strands as they grow. Sampling hairs close to the scalp can provide approximately a 3-month period of detection for alcohol and drugs. The collection process is straightforward, tamper-resistant, and easy to transport.

A sample size of 1.5 inches, consisting of roughly 200 strands (comparable to a #2 pencil), should yield 100mg of hair—the optimal amount for both screening and confirmation purposes. For EtG, additional tests, or those exceeding 10 panels, a sample weighing 150mg is advisable. Using a jeweler's scale for weighing is recommended. In the absence of scalp hair, an equivalent weight of body hair is acceptable. When discussing head hair, it specifically means scalp hair, while body hair encompasses other types like facial or axillary hair.

Process Overview

The drug test result process in a lab comprises four stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the laboratory system. The step includes ensuring proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any data entry not managed by an electronic chain of custody.

Screening acts as the first rapid assessment for substances of abuse. While it's economical for excluding drug use in most samples, a positive screen needs confirmation for legal admissibility. Presumptive positive Screening samples require further Analysis.

Samples identified as presumptively positive during Screening undergo Extraction, where additional hair is prepared from the primary sample. Extraction involves concentrating the drugs from the hair at a lower level compared to other methods (e.g., urine or oral fluid), making hair drug screening notably challenging.

Confirmation of any positive outcome from Screening is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleansed prior to confirmation if necessary. The complete lab process, from Accessioning through Confirmation, undergoes oversight according to the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditations.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can point to drug use for up to 90 days, whereas urine tests have a more limited detection span.
• Challenging to manipulate: Hair drug testing is difficult to deceive, ensuring more reliable results.
• Shows usage trends: It can exhibit a timeline of drug use over an interval, unlike tests that only indicate recent consumption.

Limitations:

• Unavailable for recent usage: Drugs take around 5-7 days to emerge as detectable in hair.
• Cost: Generally, hair drug tests come at a higher cost compared to other testing methods.
• Result variability: Elements such as hair color and personal hair growth can influence drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", the examination itself analyzes the actual 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.
