Hair Follicle Drug Testing - Primera, TX

What it is, How it works

With the rise of hair testing, it has established itself as an effective means for identifying drug and alcohol consumption. Hair captures a lasting account of alcohol and drug use by embedding biomarkers in the hair strand's fibers as it grows. Hair gathered near the scalp can provide a detection period of up to around three months for alcohol and drugs. It's straightforward to gather, challenging to tamper with, and easy to transport.

A sample measuring 1.5 inches with roughly 200 hair strands (akin to a #2 pencil) nearest to the scalp provides 100mg of hair, which is optimal for testing and verification. For tests with EtG, additional panels, or above 10 panels, 150mg is suggested. It's advised to weigh the sample using a jeweler’s scale. In cases where scalp hair is not accessible, an equivalent portion of body hair may be used. By head hair, we mean only scalp hair. Body hair includes facial, axillary, and other such hair types.

Process Overview

The drug testing procedure in a lab encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning phase incorporates the sample into the lab's system. It involves ensuring the sample is securely sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and executing any extra data input needed outside the electronic chain of custody system.

Screening serves as a preliminary assessment for drugs of abuse. While it is a cost-efficient method to exclude drug use in most samples, any positive results must undergo confirmation for legal admissibility. Presumed positive samples during Screening require secondary validation.

Should a sample show presumptive positivity during the Screening stage, additional hair is extracted from the original sample and prepped for Extraction. Here, drugs are removed from hair at concentrations much lower compared to other methods (such as urine or oral fluid), making hair drug testing one of the most complex methods to conduct.

Any positive Screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation if needed. The whole lab process from Accessioning to Confirmation undergoes evaluation under CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection: Hair drug tests trace drug use for up to 90 days, surpassing the shorter window of urine tests.
• Challenges in falsification: It is notably hard to falsify a hair drug test, thus enhancing result accuracy.
• Offers historical insights: It provides an account of drug use patterns over time, beyond just recent activity.

Limitations:

• Inability to detect immediate use: Drugs take about 5-7 days to become detectable in hair.
• Expenditure: Hair drug tests generally incur higher costs compared to other testing methods.
• Result variances: Attributes such as hair color and individual hair growth changes can influence drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests", these tests analyze the hair strand itself and not the follicle beneath the scalp.
