Accredited Drug Testing offers comprehensive hair follicle drug screenings in La Feria, Texas. If you're seeking a hair substance or alcohol test, we specialize in hair examinations and have facilities nationwide for such tests. Typically, 1.5 to 2 inches of head or body hair is necessary. These tests can detect drugs, alcohol/ETG, or be customized for other analyses.

Recently, drug testing methods increasingly involve a hair follicle drug test. Many employers, judicial systems, and Substance Abuse experts now prefer hair tests over urine tests. These tests support zero-tolerance policies of employers, probationary monitoring by courts, and provide advantages like the extended detection window, accuracy, and a secure collection method, although urine tests remain the best for recent use detection.

What it is, How it works

Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. Hair acts as a historical record for substance intake, capturing biomarkers within the strands as they grow. A sample gathered near the scalp can reveal drug and alcohol use for up to about three months. Hair sampling is straightforward, hard to tamper with, and convenient for shipping.

A sample size of 1.5 inches consisting of roughly 200 hairs (similar in size to a #2 pencil) from near the scalp yields a 100mg sample, which is optimal for testing and verification. For tests such as EtG, addons, or those exceeding 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale for accurate measurement. In cases where scalp hair isn’t available, a similar quantity of body hair can be taken. By head hair, we mean only scalp hair. Body hair encompasses all other hair varieties (e.g., facial, axillary, etc.).

Process Overview

The primary steps in lab processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes entering samples into the lab's system. This step verifies proper sealing and shipping of samples, assigns a LAN (Laboratory Accessioning Number), and completes missing data entry not provided electronically.

Screening gives an initial, rapid assessment for drugs. While it is a cost-effective method to rule out drug use in many samples, any positive screen must be confirmed for court acceptability. Presumptive positive samples from the Screening must undergo a secondary verification.

If during Screening, a sample returns a presumptive positive, additional hair is taken from the original sample for Extraction. In this phase, drugs are isolated from the hair at much lower levels than other methods like urine or oral fluid testing, making hair analysis particularly challenging.

Verification of positive results occurs through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positives are washed as necessary before confirmation. The entire lab process, from Accessioning through to Confirmation, is inspected according to the CAP (College of American Pathologists) Hair category and ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug evaluations can spot drug use up to 90 days prior, unlike urine tests with shorter detection ranges.
  • Hard to manipulate: Cheating on a hair drug test is quite tough, ensuring more reliable outcomes.
  • Historical usage data: Provides an overview of drug consumption over time, not merely recent activity.

Limitations:

  • Inability to detect recent usage: Drugs take about 5-7 days to be discernible in hair.
  • Expense: Hair drug tests typically cost more than other testing methods.
  • Potential result variability: Drug metabolite levels can be influenced by attributes like hair color and personal hair growth differences.

Note: Despite being colloquially termed "hair follicle tests", the actual test examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in La Feria, TX, is grounded in its superior detection accuracy and reliability.
