Hair Follicle Drug Testing - Lucas, TX

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. Hair captures a prolonged history of substance use by embedding biomarkers within the strands of the hair as it grows. When collected near the scalp, hair can offer up to a three-month window of detection for various substances. Hair is straightforward to gather, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches of approximately 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, a specimen of 150mg is advisable. It's recommended to weigh the specimen using a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair can be collected. When we mention head hair, we're specifically referring to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The main stages in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step in entering a sample into a lab's system. This process involves ensuring the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and finishing any remaining data entry that isn’t covered by an electronic chain of custody system.

Screening is a preliminary and rapid evaluation for drug abuse. Although Screening is an economical method to eliminate drug presence in the majority of samples, a positive result must be confirmed for it to be valid in legal settings. Any samples that test positive during Screening will require further confirmation.

Should a sample yield a presumptive positive during the Screening phase, additional hair is extracted from the initial sample for further analysis during the Extraction phase. Here, drugs are extracted from the hair at concentrations much lower than those found in other methods like urine or oral fluid. Hence, hair drug testing is considered one of the most challenging methods to execute.

Confirmation of any positive results obtained in Screening is conducted through GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples that show presumptive positive results undergo cleaning before confirmation, as necessary. The complete lab process from Accessioning to Confirmation is checked under both the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, whereas urine tests have a shorter detection duration.
• Hard to falsify: Cheating is very difficult, resulting in more reliable results.
• Offers historical insight: It reveals a timeline of drug use over an extended period, not just recent consumption.

Limitations:

• Unable to identify recent usage: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug assessments tend to be costlier than alternative testing methods.
• Result variability: Factors such as hair color and individual differences in hair growth can influence the drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests," the analysis actually examines the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When compared to traditional urine tests, hair testing in Lucas, TX offers superior accuracy and reliability. Despite the prevalence of urine testing, hair analysis extends an unmatched detection window. Why do hair follicle tests stand out? Because they efficiently uncover drug use patterns up to 90 days back, offering a broader picture of an individual's substance usage history. This is why many employers favor hair testing, ensuring stricter adherence to zero-tolerance policies.

Extended Detection Window

One of the defining advantages of hair follicle tests in Lucas, TX is their extended detection window. These tests can trace drug usage over the past 90 days, providing employers with a comprehensive understanding of a person’s substance habits. Such an extensive timeline is invaluable for organizations committed to maintaining a drug-free environment. Therefore, these tests are particularly favorable for roles requiring utmost accountability and responsibility.

Tamper-Resistant Testing Method

The inherent design of hair follicle testing makes it an exceptional choice in Lucas, TX for tamper-resistant testing. The challenge of adulterating or manipulating a hair sample means results are more trustworthy than those from urine tests. Employers and legal entities rely on the certainty provided by hair testing, minimizing risks associated with drug test cheating.
Thus, hair follicle tests are favored for their reliability and near-impossibility of sample substitution.
