Hair Follicle Drug Testing - Callahan, CA

What it is, How it works

Hair analysis is widely recognized as a robust method for identifying drug and alcohol consumption. It captures an extended timeline of substance use by securing biomarkers within the strands of developing hair. When hair is harvested near the scalp, it can offer a detection timeframe of roughly up to three months for both drugs and alcohol. Collection is straightforward, manipulation is relatively challenging, and transportation is uncomplicated.

A sample of around 1.5 inches, consisting of about 200 strands (approximately the thickness of a #2 pencil) sourced closest to the scalp, yields 100mg, which is an optimal amount for both screening and validation. For EtG, additional tests, or assessments exceeding 10 panels, 150mg is suggested. It’s advisable to measure the sample using a jeweler’s scale. If scalp hair is missing, an equivalent quantity of body hair can be used. When mentioning head hair, it pertains solely to scalp hair. Body hair includes all other types (such as facial and axillary hair).

Process Overview

The laboratory procedure for processing drug test results involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial sample processing within a lab’s system. Steps include verifying proper sealing and shipping of the sample, assigning a LAN (Laboratory Accessioning Number), and completing additional data entry if not provided by an electronic chain of custody system.

During Screening, there is an initial rapid assessment for drugs of abuse. Although Screening offers a cost-efficient method for ruling out drug use in most samples, any positive result must be confirmed for legal admissibility. Samples that are presumptive positives in Screening mandate subsequent confirmation.

If a sample returns a presumptive positive during the Screening phase, more hair is extracted from the original sample and prepared for Extraction. During Extraction, drugs are isolated at a much lower concentration compared to other methods (like urine or oral fluid), making hair drug testing one of the more challenging methodologies to execute.

The Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The entire process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the standards of ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests that offer a shorter period of detection.
• Hard to manipulate: Cheating a hair drug test is notably difficult, ensuring more reliable results.
• Offers temporal usage pattern: It unveils a timeline of drug use over time, not merely recent consumption.

Limitations:

• Incapacity to detect recent intake: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Hair drug testing usually costs more than other methods.
• Result variability: Elements like hair color and individual growth rates may influence drug metabolite concentration in hair.

Note: Although frequently labeled as "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
