Hair Follicle Drug Testing - Jarreau, LA

What it is, How it works

The utilization of hair testing has emerged as a potent method for uncovering drug and alcohol consumption. Hair acts as a repository for a long-term record of substance use by embedding biomarkers within the fibers as the hair strand develops. When gathered near the scalp, hair samples can reveal alcohol and drug usage for about three months. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.

A segment measuring 1.5 inches, comprising roughly 200 hair strands (approximating the thickness of a #2 pencil) closest to the scalp, will yield 100mg of hair, the recommended quantity for initial and confirmatory testing. For comprehensive tests such as EtG add-ons or those exceeding 10 panels, it is advised to collect 150mg of hair. We suggest verifying the specimen weight using a jeweler's scale. Should scalp hair be unavailable, an equivalent portion of body hair is an acceptable alternative. The term "head hair" specifically denotes scalp hair, while "body hair" pertains to other types such as facial or underarm hair.

Process Overview

The drug testing process in a laboratory is composed of four critical phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, samples are initially integrated into the laboratory’s workflow. This includes confirming that the sample was appropriately sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any manual data entry not captured by electronic chain of custody systems.

Screening serves as a preliminary assessment for drug presence. While it is a cost-efficient method to dismiss drug use in most cases, any positive screenings require validation to be officially recognized in legal settings. Therefore, secondary confirmation is essential for samples testing positive in Screening.

When a sample tests positive in the Screening phase, additional hair is extracted from the original sample to undergo Extraction. At this point, drugs are isolated from hair in much smaller concentrations compared to alternative methods (e.g., urine or saliva tests), making hair drug testing a particularly challenging technique to execute.

Verification of any Screening positives occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as necessary. The entire sequence from Accessioning to Confirmation is conducted with oversight from both the CAP (College of American Pathologists) Hair designation and accredited in line with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests can reveal drug intake over a span of 90 days, in contrast to urine tests which offer a shorter detection timeframe.
• Resistance to tampering: Hair drug tests are notoriously hard to compromise, which enhances the accuracy of the findings.
• Chronological usage insight: This testing can sketch a timeline of substance usage patterns, not merely recent consumption.

Limitations:

• Non-detection of recent intake: Drugs typically take 5-7 days before becoming traceable in hair.
• Expense: Hair drug tests incur more costs relative to alternative testing techniques.
• Result variability: Factors like hair color and individual hair growth differences can influence the drug metabolite concentrations in hair.

Note: Although commonly described as "hair follicle tests," the procedure analyzes the hair strand rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Jarreau, LA, hair follicle testing is proving to be more advantageous compared to traditional urine testing. Hair tests offer superior detection accuracy, capturing a wider window of drug use, often up to 90 days. Urine tests, commonly employed, fail to provide the same level of reliability when tracking long-term substance use. With hair tests, employers gain a more comprehensive view of an individual’s substance history, reassuring them of the test's precision.

Extended Detection Window

Offering an extended detection window of up to 90 days, hair follicle testing in Jarreau, LA, allows employers to garner a detailed history of an individual's substance use. Unlike urine tests, which only reveal recent drug use, hair tests give a broader perspective. This comprehensive approach aids in making informed hiring decisions, highlighting prolonged substance use that might otherwise go unnoticed with standard tests.

Tamper-Resistant Testing Method

Hair follicle tests in Jarreau, LA, lead the way in reducing sample adulteration risks. This method ensures that the results are trustworthy and credible. Unlike other testing methods, it is nearly impossible to tamper with a sample, providing companies and individuals peace of mind regarding test integrity. These tamper-resistant attributes make hair testing a reliable choice, ensuring results are reflective of true substance use.
