Hair Follicle Drug Testing - Cazadero, CA

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the hair strand's fibers as it grows, hair delivers a prolonged history of alcohol and drugs. When taken from near the scalp, hair can reveal alcohol and drug use for up to roughly 3 months. It is easy to collect, not easily tampered with, and straightforward to transport.

A 1.5-inch section consisting of around 200 hair strands (similar in size to a #2 pencil) from close to the scalp is needed to obtain 100mg of hair, the perfect sample for preliminary and confirmatory testing. For EtG, additional assessments, and/or evaluations beyond 10 panels, a sample weighing 150mg is advised. It is suggested to use a jeweler’s scale for measuring the specimen. If head hair is not available, equivalent body hair may be used. Head hair refers only to scalp hair, while body hair encompasses all other types of hair (such as facial and axillary).

Process Overview

The key steps in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the primary step of incorporating a sample into the lab's system. This step ensures the sample was properly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and completes any remaining data entry missing from an electronic chain of custody.

Screening provides an initial rapid assessment to detect substances of abuse. While Screening is a cost-effective measure to eliminate drug use in most samples, a positive outcome must be validated for court acceptance. Any samples showing a presumptive positive in Screening need follow-up confirmation.

If a Screening test shows a presumptive positive, additional hair is collected from the original sample for Extraction. Here, drugs are separated from hair at much lower concentrations than in other techniques (such as urine or oral fluid), leading to hair drug tests being the most challenging to conduct.

Confirmation of a positive screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positivity undergo a washing process prior to confirmation if necessary. The entire lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and follows ISO / IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug analysis can determine drug use up to 90 days back, offering a larger window than urine tests.
• Hard to manipulate: Hair drug tests are tough to manipulate, increasing the accuracy of results.
• Shows historical usage: Offers a record of drug usage patterns over time, not just recent intake.

Limitations:

• Inability to detect recent intake: Drugs need roughly 5-7 days post-consumption to become traceable in hair.
• Expense: Typically, hair drug testing is pricier compared to other drug testing approaches.
• Result variability: Elements like hair color and personal hair growth differences may alter the drug metabolite levels in hair.

Note: Although called "hair follicle tests", this test examines the hair strand itself, not the follicle beneath the skin.
