Hair Follicle Drug Testing - Thurston, NE

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair encapsulates a comprehensive history of substance usage by integrating biomarkers into the strands as they grow. When extracted close to the scalp, it offers up to three months of detection capability for alcohol and other drugs. Hair collection is straightforward, resistant to tampering, and easy to transport.

A sample size of 1.5 inches consisting of roughly 200 hairs (approximately the thickness of a #2 pencil) taken closest to the scalp will yield 100mg of hair, the preferred sample size for analysis. For tests like EtG, additional screenings, or panels exceeding 10, a 150mg specimen is advised. It is suggested to use a jeweler’s scale for weighing the sample. If scalp hair is unavailable, the same quantity of body hair can be used. When head hair is mentioned, it specifically refers to scalp hair only, whereas body hair includes all other hair types (facial, axillary, etc.).

Process Overview

There are four key phases in the lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first phase, involving integrating the sample into a lab system. This process ensures that the sample was securely sealed and correctly delivered, allocates a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry not covered by an electronic chain of custody system.

Screening is a preliminary examination for substances of abuse. While Screening is a cost-efficient method to exclude drug consumption in most cases, a positive screen must be verified to be valid in legal proceedings. Samples deemed presumptive positive during Screening require a follow-up confirmation.

When a sample is flagged as presumptive positive in Screening, more hair is extracted from the original sample and prepped for Extraction. During this stage, substances are extracted from hair at significantly lower levels than other methods (e.g., urine or oral fluid), underscoring the challenges of hair drug screening.

Validation of a positive result discovered during Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked as presumptive positive are cleaned before confirmation if necessary. The complete lab process, from Accessioning to Confirmation, is vetted against both the CAP (College of American Pathologists) Hair standards and compliance with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests have the capacity to detect drug use for up to 90 days, a longer timeframe compared to urine tests.
• Resilience against tampering: Manipulating results in a hair drug test is notably challenging, thus enhancing accuracy.
• Chronological data: It offers insight into drug usage over time rather than just recent ingestion.

Limitations:

• Inability to detect recent intake: Drugs require about 5-7 days to become detectable in hair strands.
• Expense: Hair drug tests generally entail higher costs than other testing approaches.
• Result fluctuations: Elements like hair color and individual hair growth differences can influence metabolite concentrations.

Note: Despite often being termed as "hair follicle tests," the analysis targets the hair strand, not the follicle beneath the scalp.
