Hair Follicle Drug Testing - Millican, TX

What it is, How it works

Hair analysis has emerged as an effective means for identifying substance use, including drugs and alcohol. Hair can trap biomarkers within the fibers of the growing strands, providing a lengthy history of substance intake. When clipped near the scalp, hair offers a detection window of up to three months for alcohol and drugs. Collection is straightforward, has a low chance of tampering, and is convenient to transport.

A 1.5-inch segment of roughly 200 strands (equivalent in size to a #2 pencil) nearest the scalp equals 100mg, constituting an optimal amount for screening and validation. For EtG, additional tests, or assays beyond 10 panels, a 150mg quantity is preferable. We recommend using a jeweler’s scale for accurate measurement. If scalp hair is unavailable, a similar volume of body hair is acceptable. "Head hair" refers strictly to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

Drug test results in the lab undergo four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial incorporation of a sample into the laboratory system. This step ensures the sample was well-sealed and properly transported, assigns a random Laboratory Accessioning Number (LAN), and completes any necessary information not provided electronically.

Screening provides a preliminary check for substance abuse. While a cost-efficient method to discount drug use among most samples, any positive screenings must be substantiated for legal acceptance. Samples yielding positive screening results need further verification.

Should a screening indicate a potential positive, more hair is extracted from the original sample for the Extraction phase. At this stage, drugs are isolated at lower concentrations from hair compared to other methods (e.g., urine or oral fluid), making hair drug testing particularly challenging.

Positive screening confirmations employ GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive are washed before confirmation if required. The entire validation procedure from Accessioning to Confirmation adheres to both the College of American Pathologists (CAP) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests reveal drug use up to 90 days prior, while urine tests provide shorter detection timeframes.
• Difficult to manipulate: Cheating a hair drug test is challenging, enhancing result accuracy.
• Chronological use data: Offers insights into usage patterns over time rather than just recent consumption.

Limitations:

• Inability to detect recent use: Drugs only become discernible in hair approximately 5-7 days post-ingestion.
• Expense: Generally higher costs are associated with hair drug testing compared to other methods.
• Result variability: Variables such as hair color and individual growth rates can influence drug metabolite levels in hair.

Note: Despite the common terminology "hair follicle tests", the analysis actually examines the strands, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Millican, TX, hair follicle testing surpasses urine tests with enhanced detection accuracy. While urine tests are standard, hair examinations offer superior reliability, identifying substance use over extended periods, which urine tests may not efficiently cover.

Hair testing's longer detection period provides a more comprehensive view of drug usage histories. This increased accuracy ensures more dependable outcomes compared to the traditional urine testing approach.

Extended Detection Window

Millican, TX employers benefit from hair testing's extended detection window. This method highlights drug use over an up to 90-day period, offering a more thorough view of a person's substance history compared to shorter-range testing methods.

The longer detection span enables comprehensive assessments of any applicant or employee's long-term drug use, promoting better-informed hiring and monitoring decisions.

Tamper-Resistant Testing Method

Hair follicle tests in Millican, TX offer robust tamper resistance. Unlike urine tests, they are significantly less vulnerable to adulteration, thus delivering consistent and credible results, securing the integrity of the testing process.
