Hair Follicle Drug Testing - Garner, TX

What it is, How it works

Hair analysis has emerged as an effective resource for identifying alcohol and drug consumption. Hair strands offer an extended timeline for detecting alcohol and drug use by encapsulating biomarkers within the fiber of the growing strand. Hair samples collected near the scalp can provide an approximately 3-month detection span for alcohol and drugs. The sample collection is straightforward, challenging to tamper with, and convenient for transport.

A 1.5-inch segment containing roughly 200 hair strands (comparable to the thickness of a #2 pencil) from near the scalp yields 100mg, which is optimal for both screening and confirmation analyses. For EtG, add-ons, or tests that exceed 10 panels, a 150mg sample is advisable. Using a jeweler's scale to measure the specimen is recommended. If scalp hair is not available, body hair of equivalent weight can be utilized. "Head hair" specifically denotes scalp hair, while "body hair" encompasses other hair types, including facial and axillary hair.

Process Overview

The laboratory processing for a drug test result is divided into four critical phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the preliminary integration of a sample into the laboratory’s system. This process includes verifying the sample's seal and shipping integrity, generating a random LAN (Laboratory Accessioning Number), and completing any further data input that an electronic chain of custody system did not provide.

Screening entails an initial expedited evaluation for drug abuse. While it's a cost-efficient strategy for ruling out drug usage in most samples, a positive screening result requires confirmation to be court-admissible. All samples that record presumptive positives during screening require follow-up confirmation.

Should a sample record a presumptive positive at the Screening stage, additional hair is extracted from the initial sample for the Extraction phase. This stage involves retrieving drugs from hair at significantly lower concentrations compared to alternate methods (e.g., urine or oral fluid), which makes hair analysis the most challenging drug testing technique.

The Confirmation of any presumptively positive outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives undergo a cleansing process before confirmation if necessary. The entire laboratory procedure, from Accessioning to Confirmation, is assessed under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Lengthy detection window: Hair tests can recognize drug usage for up to 90 days, versus the shorter scope of urine tests.
• Cheating is complex: The difficulty in deceiving a hair drug test enhances result accuracy.
• Historical usage data: It outlines a timeline of drug usage over time, not merely recent consumption.

Limitations:

• Recent use detection issue: 5-7 days are necessary before drugs are traceable in hair.
• Expense: Hair drug testing tends to be pricier than other drug evaluation methods.
• Result variability: Variables like hair color and individual growth rates can influence drug metabolite concentrations within hair.

Note: While commonly labeled as "hair follicle tests", the examination is conducted on the hair strand itself, and not on the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Garner, TX, hair follicle testing is superior to urine testing for its higher accuracy. Hair tests cover a wider window of detection and offer results that are difficult to dispute. Beyond simply confirming presence of substances, this testing method provides a long-term overview. In contrast, while urine tests are suitable for recent detections, they miss the longer history afforded by hair analysis.

Extended Detection Window

The extended detection window available through hair follicle testing offers a significant edge in Garner, TX. It allows for tracking drug use up to 90 days prior, offering employers comprehensive insight into an individual's substance history. This capability empowers more informed decision-making in hiring, and it ensures consistency in maintaining a drug-free environment in the workplace.

Tamper-Resistant Testing Method

Hair follicle testing in Garner, TX is renowned for its tamper resistance, greatly reducing concerns of adulteration. Unlike other methods, altering hair samples is near impossible, thus guaranteeing the reliability and authenticity of test results. This assurance of uncompromised data makes hair testing an excellent choice for those requiring verified results.
