Hair Follicle Drug Testing - Indianola, CA

What it is, How it works

The process of hair testing is increasingly acknowledged as an effective measure for detecting drug and alcohol consumption. Hair strands capture biomarkers within the fibers as they grow, providing a comprehensive timeline of substance use. Collected from near the scalp, hair offers an extended detection period of roughly three months for substances. Hair collection is straightforward, relatively tamper-proof, and easy to transport.

A segment measuring 1.5 inches, containing approximately 200 hairs (comparable in size to a #2 pencil), yields 100mg of hair, the preferred quantity for both screening and confirmation. For EtG, additional items, and tests surpassing 10 panels, a larger sample of 150mg is suggested. It's advisable to weigh the hair using a jeweler’s scale. If scalp hair isn't available, an equivalent volume of body hair can be used. "Head hair" specifically designates hair from the scalp, whereas "body hair" encompasses all other types (including facial and axillary hair).

Process Overview

Drug test processing at the laboratory involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, samples undergo initial processing within a lab’s system, ensuring they are sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any outstanding data entries absent from an automated chain of custody.

Screening provides an initial assessment for potential drug abuse, offering a budget-conscious method to exclude drug use in most samples. However, a positive result from Screening necessitates confirmation for court acceptability. Any samples indicating a positive result in Screening require further confirmation.

Should a sample show preliminary positive results during Screening, further hair is extracted from the initial sample for Extraction. This involves retrieving drugs from hair at notably lower concentrations than in other testing methods (e.g., urine or saliva), highlighting the complexity of hair drug testing compared to other methodologies.

Positively screened results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as necessary. The entire procedure—from Accessioning through to Confirmation—is rigorously evaluated under the CAP (College of American Pathologists) Hair classification and is compliant with ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection period: Hair tests can identify drug usage for as long as 90 days, surpassing the shorter period detected by urine tests.
• Hard to manipulate: Cheating a hair test is exceedingly challenging, ensuring precise outcomes.
• Reveals historical drug use: Offers insight into a sustained pattern of drug use instead of merely recent activities.

Drawbacks:

• Inability to identify recent use: Drugs only become detectable in hair after roughly 5-7 days.
• Expense: Hair tests often incur higher costs compared to alternative drug testing techniques.
• Variable outcomes: Drug metabolite concentrations in hair can vary due to factors such as hair color and individual hair growth rates.

Note: Although commonly termed "hair follicle tests", the examination focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Indianola, CA, hair follicle testing presents clear advantages over urine tests. Their capacity for superior detection accuracy makes them a preferred choice. Hair tests capture a wider history of drug use, offering employers and legal entities a robust tool for analysis. Unlike urine tests, hair samples eliminate the risks of short detection windows, thus enhancing credibility.

Extended Detection Window

With a testing window extending up to 90 days, hair follicle analyses in Indianola, CA provide a comprehensive examination of a subject's prior substance use. This extended period allows employers to scrutinize longer histories, offering insights that urine tests cannot match. Gaining such a complete view enhances decision-making processes significantly, securing informed choices for potential hires.

Tamper-Resistant Testing Method

Hair follicle testing in Indianola, CA, offers a testing method that substantially minimizes chances of sample tampering. Unlike urinalysis, hair samples are difficult to manipulate or alter. The nature of hair testing involves a stringent collection process that ensures the integrity of the samples, thus delivering conclusive and trustworthy results.
