Hair Follicle Drug Testing - Pacifica, CA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair offers an extended historical record of substance use by encasing biomarkers within the hair shaft's fibers as it grows. When gathered near the scalp, hair can yield a detection timeframe of up to about three months for alcohol and substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A sample size of 1.5 inches, approximately 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp will provide 100mg of hair, the optimal amount for both screening and verification. For EtG, additional tests, and/or assessments beyond 10 panels, 150mg of the specimen is suggested. It's advisable to weigh the sample using a jeweler's scale. If scalp hair is lacking, an equivalent quantity of body hair is acceptable. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory steps for processing a drug test outcome are broadly categorized into Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary handling of a specimen within a lab's system. This step includes ensuring the specimen's seal and shipment were handled correctly, generating a random LAN (Laboratory Accessioning Number), and finalizing any additional information entries not covered by an electronic chain of custody system.

Screening is an initial methodical test for detecting drug abuse. Although Screening is an economical approach to exclude drug use in the majority of samples, a positive result from Screening needs verification to stand in legal settings. Samples that show potential positivity in Screening necessitate further confirmation.

If a specimen registers potential positivity during Screening, additional hair is extracted from the original sample and set for Extraction. Drugs are isolated from the hair at notably lower concentrations compared to other methods (such as urine or oral fluid), which contributes to the complexity of hair drug analysis.

Verification of any positive Screening results utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleansed prior to Confirmation as required. The full laboratory process from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can identify drug intake up to 90 days, unlike urine tests with shorter detection durations.
• Challenging to falsify: Hair drug tests are notably resistant to deception, thereby ensuring result precision.
• Yields historical patterns: It offers insights into substance use patterns over time, rather than solely recent usage.

Limitations:

• Incapable of spotting recent consumption: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Generally, hair drug analyses are pricier compared to other testing techniques.
• Result variability: Aspects like hair color and individual hair growth variances can influence the level of drug metabolites in hair.

Note: Despite being commonly termed "hair follicle tests", the procedure examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Pacifica, CA, provides a significant edge over traditional urine tests, thanks to superior detection accuracy and reliability. Where urine tests might miss earlier consumptions, hair tests offer a longer detection period, providing a fuller picture of substance use history. Employers find this detailed insight valuable for maintaining a safe and productive working environment.

Unlike urine tests, which might be influenced by evasion tactics, hair tests collected under observation ensure that results remain tamper-proof. This reliability makes hair tests an essential tool for enforcing zero-tolerance policies effectively.
