Hair Follicle Drug Testing - Sleepy Hollow, CA

What it is, How it works

Hair testing is increasingly valued as an effective method for detecting alcohol and drug consumption. Hair encapsulates long-term history of alcohol and drug usage by embedding biomarkers within the fiber of the hair as it grows. When collected from near the scalp, it provides detection capability for alcohol and drugs over roughly a three-month span. The collection of hair is straightforward, less prone to tampering, and convenient to transport.

Collecting a 1.5-inch segment consisting of approximately 200 hair strands (similar to a #2 pencil's width) close to the scalp results in a 100mg sample, ideal for screening and confirmation processes. For EtG, additional tests, and those exceeding 10 panels, a 150mg sample is preferable. It is advisable to weigh the specimen using a jeweler's scale. If scalp hair is unobtainable, an equivalent volume of body hair may be utilized. "Head hair" pertains solely to scalp hair, whereas "body hair" encompasses all other varieties (facial, axillary, etc.).

Process Overview

The lab process for drug test results comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into the lab's system. This step ensures the sample is sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry absent from an electronic chain of custody.

Screening performs an initial, expedient assessment for substances of abuse. Though cost-effective for ruling out drug use in most instances, a positive screen requires confirmation for legal admissibility. Samples with presumptive positives in Screening necessitate further confirmation.

Should a sample show presumptive positivity in Screening, additional hair is taken from the original sample for Extraction. At this stage, drugs are extracted from hair at concentrations substantially lower than other methods (e.g., urine or oral fluids), substantiating hair drug screening as the most challenging methodology.

Confirmation for any positive screen is facilitated via GC/MS, GC/MS/MS, or LC/MS/MS. Necessary presumptive positives are washed preceding confirmation. The lab process from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and accreditation adhering to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Capable of identifying drug intake for as long as 90 days, while urine tests exhibit a narrower detection time frame.
• High resistance to evasion: The probability of compromising a hair drug test is minimal, ensuring more trustworthy outcomes.
• Historical use data: Offers insight into drug use patterns over durations extending beyond immediate use.

Limitations:

• Inability to identify recent use: Drugs require an estimated 5-7 days before being traceable in hair.
• Expense: Hair drug tests typically incur higher costs than alternative drug testing methodologies.
• Result variability: Elements such as hair color and individual hair growth differences might influence drug metabolite concentrations within hair.

Note: Although sometimes called "hair follicle tests," the examination focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Sleepy Hollow, CA, hair follicle testing outshines urine testing due to its extended detection window. While urine tests capture recent drug use, hair tests reveal a much broader history, offering employers greater insight into an individual's substance use patterns.

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.
