Hair Follicle Drug Testing - Nevada City, CA

What it is, How it works

Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. Hair captures long-term traces of alcohol and drugs by trapping biomarkers in the strands as they grow. When cut close to the skin, hair can offer up to a 3-month detection timeline for both alcohol and drugs. Collecting hair is effortless, challenging to falsify, and simple to transport.

A 1.5-inch batch of around 200 hair strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg, the optimum amount for testing and verification. For EtG, supplemental tests, or analysis exceeding 10 panels, 150mg of sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is not available, an equivalent portion of body hair can be used. When discussing head hair, we mean scalp hair specifically. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test involves four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial registration of a sample into a lab’s database. This step verifies that the sample was properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.

Screening conducts an initial rapid evaluation for drug abuse. Although Screening is a cost-effective means to dismiss drug use in the majority of samples, a positive result requires confirmation to be legally valid. Any samples preliminarily positive in Screening necessitate a secondary verification.

During the Screening stage, if a sample is tentatively positive, additional hair is extracted from the initial sample and prepped for Extraction. Here, drugs are extracted from hair at a much lower concentration compared to other methods (like urine or oral fluid), which makes hair drug screening a complex method to execute.

Confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples presumed positive are cleansed before confirmation as necessary. The full lab method from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair directive and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can reveal drug use up to 90 days, in contrast to urine tests with a briefer detection span.
• Cheating difficulty: It is quite tough to deceive a hair drug test, enhancing result precision.
• Historical data provision: It offers a drug usage pattern over time, rather than just recent use.

Limitations:

• Inability to identify recent use: It generally takes 5-7 days for drugs to be discernible in hair.
• Expense: Hair drug tests are typically pricier than other drug testing approaches.
• Result variations: Elements including hair color and personal differences in hair growth can influence the drug metabolite concentration in hair.

Note: Although frequently called "hair follicle tests", the test actually examines the hair strand and not the subcutaneous hair follicle
